AMD vs Intel: Which CPUs Are Better in 2021?

(Image credit: Tom's Hardware)

If you're looking for the best CPUs for Gaming or the best workstation CPU, there are only two choices to pick from – AMD and Intel. That fact has spawned an almost religious following for both camps, and the resulting AMD vs Intel flamewars, making it tricky to get unbiased advice about the best choice for your next processor. But in many cases, the answer is actually very clear. In fact, for most users, it's now a blowout win in Intel's favor, as you can see in our CPU Benchmarks Hierarchy. That's an amazing reversal of fortunes for the chipmaker after its decade of dominance was completely overturned by AMD's Ryzen 5000 chips.

This article covers the never-ending argument of AMD vs Intel desktop CPUs (we're not covering laptop or server chips). We judge the chips on seven criteria based on what you plan to do with your PC, pricing, performance, driver support, power consumption, and security, giving us a clear view of the state of the competition. We'll also discuss the lithographies and architectures that influence the moving goalposts. Overall, there's a clear winner, but which CPU brand you should buy depends mostly on what kind of features, price, and performance are important to you.

If you're looking for the fastest chip on the market, you should look to Intel's potent new Alder Lake series. Intel's Alder Lake chips take the gaming crown from AMD, and also rival or beat AMD in all meaningful performance metrics, like single- and multi-threaded productivity workloads. You can see the disruptive results in our Intel Core i9-12900K and Core i5-12600K review, and we've also added both our Windows 10 and 11 testing to our CPU benchmark database. We've also thrown in results with both DDR4 and DDR5 memory for good measure. We're working to add in a more expansive update to some of the text below, but rest assured that Intel has retaken the lead in several of the categories. Here's how that looks in several key faceoffs in important price bands:

You can see how all of these processors stack up in our AMD vs Intel CPU Benchmarks Hierarchy, but the landscape had changed in the wake of AMD's newest processors, the Ryzen 9 5950X and Ryzen 9 5900X, not to mention the Ryzen 5 5600X. At their debut, the Ryzen 5000 series were the highest-performing chips on the market and beat Intel in every metric that matters, including gaming, application performance, power consumption, and thermals. Intel now has the edge with the Alder Lake chips, but AMD's Ryzen lineup certainly remains competitive in a few key areas. For more info, you can head to our expansive in-depth coverage of the Ryzen 5000 series, including pricing, benchmarks, and availability.

Intel's Alder Lake has completely redefined x86 desktop PC chips with a new hybrid architecture that delivers amazing levels of performance. Not to be upstaged, AMD has its new CPUs with 3D V-Cache headed to production later this year. Those chips will bring up to 15% more gaming performance courtesy of up to an almost-unthinkable 192MB of L3 cache bolted onto a souped-up Zen 3 processor. That means the AMD vs Intel battle could shift towards the tail end of the year, but this is the tale of the tape for the current state of the market.

Here are the results of our analysis and testing. In the following sections, we'll go over the in-depth details of how we came to our conclusions for each category.

AMD's relentless onslaught with its Zen-based processors has redefined our expectations for both the mainstream desktop and the HEDT markets, originally catching Intel flatfooted as it remained mired on the 14nm process and Skylake architectures. The past several years have seen AMD CPUs go from value-focused and power hungry chips to leading-end designs that deliver more cores, more performance, and lower power requirements.

Intel fought back by slowly adding features and cores across its product stack, but that also resulted in negative side effects, like more power consumption and heat generation. That only served to highlight the company's struggles on the design and fabrication side of its operation.

The AMD vs Intel CPU conversation has changed entirely, though, as Intel has now undercut AMD's price-to-performance ratio entirely with the Alder Lake chips. Additionally, Alder Lake comes with the most disruptive change to Intel's CPU overall SoC design methodology, not to mention core architectures, that we've seen in a decade. They also come with the new 'Intel 7' process that has proven to be exceptionally competitive. That shifted our rankings from a 7-to-4 advantage for AMD to a 7-to-5 advantage in Intel's favor.

However, Intel still hasn't eased its draconian segmentation policies that limit features, like overclockability, to pricey chips and motherboards. Intel's tactic of squeezing every penny out of every feature had allowed AMD to offer a more compelling value story across the full breadth of the consumer desktop CPU market. Alder Lake's low chip pricing and performance advantages now offset those upcharges, but Intel's decision to only bring its pricey Z-series motherboards to market at first does mean those lower chip prices will still be hampered by a 'motherboard tax' — at least until the cheaper B- and H- 600-series boards launch in the coming months. 

Given AMD's current mix of price, performance, and value, it will have to drop pricing on its Ryzen 5000 chips soon in order to remain competitive. AMD has its new CPUs with 3D V-Cache headed to production later this year, bringing up to 15% more gaming performance than the current Ryzen chips due to an almost-unthinkable 192MB of L3 cache bolted onto a souped-up Zen 3 processor. We'll have to wait and see how that works out in the real world, though, but be aware that AMD does have a response coming. 

However, Intel wins the CPU war overall right now. An AMD processor could still be the better choice depending on your needs, like if you prize the lowest power consumption or less-expensive motherboards. For now, if you want the best in gaming or application performance, overclocking or software support, or if you want productivity performance without buying a discrete GPU, Team Blue deserves your hard-earned dollars.  

AMD vs Intel CPU Pricing and Value

Update: The above sections have been altered to include Intel's Alder Lake. We'll update the sections below with Alder Lake-specific commentary this week. Stay tuned.

Pricing is the most important consideration for almost everyone, and AMD has generally been hard to beat in the value department. The company's Ryzen 5000 series processors mark an across-the-board $50 price hike, but the faster chips earn their higher price tags. The company offers a plethora of advantages, like full overclockability on most models, not to mention complimentary software that includes the innovative Precision Boost Overdrive auto-overclocking feature.

You also benefit from the broad compatibility of motherboards with the AM4 CPU socket that supports both forward and backward compatibility, ensuring that not only do you get the most bang for your processor buck, but also your motherboard investment (there are caveats with the 5000 series). AMD also allows overclocking on all but its A-Series motherboards (see our article on how to overclock AMD Ryzen), which is a boon for enthusiasts. And, in this battle of AMD vs Intel CPUs, we haven't even discussed the actual silicon yet. 

Processor Pricing by FamilyAMDIntel
Threadripper - Cascade Lake-X$900- $3,750$800 - $1,000 ($2,999)
AMD Ryzen 9 - Intel Core i9$434 - $799$422 - $549
AMD Ryzen 7 - Intel Core i7$294 -$449$298 - $409
AMD Ryzen 5 - Intel Core i5$149 - $299$157 - $272
AMD Ryzen 3 - Intel Core i3$95 - $120$97 - $154

The arrival of Intel's Comet Lake-S models has found the company adding more cores, threads, and features to its mainstream lineup, but without increased gen-on-gen pricing. That equated to a substantial reduction in price-per-core and price-per-thread metrics, but AMD reduced pricing in response to keep Intel on its toes. AMD currently holds the price-per-core advantage in the Ryzen 9 and 7 range (compared to Core i9 and i7), while Intel holds the lead in the Core i5 and i3 range (vs Ryzen 5 and 3).

Intel includes bundled coolers with its non-overclocking SKUs (you have to pay more to overclock), but they are flimsy and 'good enough,' at best. We've even seen cases where Intel's stock coolers don't provide full performance at stock settings. Intel did slightly bulk up its bundled coolers for several Rocket Lake-S models, but the aesthetic and slight thermal improvements aren't enough to match AMD's competent coolers, and they aren't available on all models. However, the company reportedly has newer coolers in the works for its next line of chips, including models with RGB.

Intel also doesn't throw in a cooler at all for its pricey overclockable K-series SKUs (see our article on how to overclock an Intel CPU). Be sure to budget in a cooler (and a beefy one at that) if you plan on overclocking an Intel processor. Meanwhile, most of AMD's bundled coolers are suitable for at least moderate overclocking. Still, those only came as a standard add-in with the previous-gen Ryzen 3000 series, most of which haven't been supplanted with new Ryzen 5000 equivalents yet. Only three of the first seven AMD Ryzen 5000 processors, the Ryzen 5 5600X, Ryzen 7 5700G, and Ryzen 5 5600G comes with a bundled cooler.

Intel not only charges a premium for its overclockable K-Series chips, but you'll also need to shell out for a pricey Z-Series motherboard for the privilege of overclocking your processor—Intel doesn't allow full overclocking on B- or H-series motherboards. Intel has now enabled memory overclocking on its B560 and H570 chipsets, and that works with any chip that is compatible with the platform, meaning all 10th-Gen Comet Lake, 11th-Gen Rocket Lake, and 11th-Gen Comet Lake Refresh processors. However, these changes only apply to 500-series models.

Intel also has a long history of rapid socket transitions, meaning the odds of dropping a new chip into your existing motherboard, or taking the older processor over to a newer board, aren't as high. Plan for limited forward and backward compatibility on the Intel side. Intel's Rocket Lake does finally bring support for PCIe 4.0 connectivity, but Intel's 500 series chipset doesn't support PCIe 4.0 like AMD's chipsets. That means you get 20 lanes from the processor only — 16 lanes for graphics and four lanes for a single M.2 port, limiting connectivity options. 

While AMD offers the most bang for your hard-earned dollar, as with any product, you can expect to pay a premium for the utmost performance, particularly the Ryzen 9 5950X. AMD's Ryzen 5000 series is the end of the line for the tried-and-true AM4 socket, so you shouldn't expect those chips to work in future AMD platforms.

However, AMD has its new CPUs with 3D V-Cache headed to production later this year. Those chips will bring up to 15% more gaming performance courtesy of up to an almost-unthinkable 192MB of L3 cache bolted onto a souped-up Zen 3 processor, and that means they may come to the AM4 socket. Only time will tell.

AMD's new Ryzen 5000 processors also come without bundled coolers for the Ryzen 9 and 7 families, but AMD says the increased performance offsets the lack of coolers and higher pricing. Our reviews back up that assertion - the Ryzen 5000 chips still offer a compelling blend of pricing and performance, provided you can find them at retail near their recommended pricing. 

Win: AMD. When you're comparing Intel vs AMD CPUs, Team Red has a compelling value story across the full breadth of its product stack, especially when we take performance-per-dollar into account. However, if you're looking for integrated graphics paired with a processor with more than four cores, Intel is currently your only choice for chips at retail, though AMD does have its Cezanne APUs coming in August. Not that we'd recommend integrated graphics for most users, particularly if you're interested in gaming—check out our recent comparison of integrated graphics on AMD and Intel processors for more detail. 

AMD vs Intel CPU Gaming Performance

In the AMD vs Intel CPU battle, AMD holds the lead in the critical price bands, particularly right in the middle and high-end of its stack, but our benchmarks show the Intel's gaming performance is no slouch, either. Below we have a wide selection of collective gaming performance measurements for the existing chips in the different price bands. You can see a much more holistic view in our CPU Benchmarks Hierarchy.

Our first four slides encapsulate performance with the new Rocket Lake and Ryzen 5000 processors included, while the remainder of the test results gives historical context to other previous-gen processors. As you can see, AMD largely leads the gaming landscape with its Zen 3-powered Ryzen 5000 processors, which now hold the advantage in both 1080p and 1440p gaming, but Intel has shrunk the gap to make gaming a closely-contested affair. The Ryzen 9 5900X slots in as the fastest gaming chip on the market, price be damned, but the Ryzen 5 5600X offers nearly the same level of performance but at a more amenable $300 price point, making it our uncontested top pick for gaming.

Intel's Core i9-11900K is nearly as fast as the vaunted Ryzen 9 5900X, particularly after overclocking, and you'd be hard-pressed to notice the difference between the two in real-world gaming sessions. The Core i7-11700K is hard to justify for gaming, but its little brother, the Core i5-11600K, is a solid chip for affordable high-performance gaming rigs. The Core i5-11400 is perhaps the most impressive Rocket Lake gaming chip – its blend of price and performance absolutely dominates the sub-$200 market and will continue to do so until AMD fields new chips.

We have in-depth head-to-head comparisons in each of the key price brackets in the following articles: 

However, bear in mind that the performance delta between Intel and AMD's comparably-priced chips often isn't worth paying a huge premium, at least for the vast majority of enthusiasts. You'd be hard-pressed to notice the small differences in gaming performance at the top of the AMD vs Intel stack, but things are more complicated in the mid-range.

You'll need a fire-breathing high-end GPU and one of the best gaming monitors with a high refresh rate to get the most out of a small performance advantage, and you'll need to game at the mundane 1080p resolution, too. Kicking your resolution up to 1440p and beyond typically pushes the bottleneck back to the GPU, so you won't gain as much from your CPU's gaming prowess. However, a bit of extra CPU gaming performance could pay off if you plan on updating your graphics card with a newer generation while keeping the rest of your system intact. We expect most builds in the mid-range to come with lesser GPUs, which generally serve as an equalizer in terms of CPU performance.

In terms of integrated graphics performance, there's no beating AMD. The company's current-gen Picasso APUs offer the best performance available from integrated graphics, and the Renoir series builds on that advantage. Unfortunately, the Renoir chips aren't available at retail (here's a look at the Ryzen 7 4750G, though), but AMD's hotly-anticipated Cezanne APUs come in August.

Winner: Tie Both companies win this round of the Intel vs AMD CPU showdown. AMD's relentless pressure has forced a renaissance in terms of CPU performance for desktop PC gaming, spurring Intel to respond with more powerful processors of its own. Taken as a whole, both companies have extremely competitive chips in the respective price ranges — you'll often be hard-pressed to notice a difference between them in real-world gaming.

If you're a gaming fanatic that prizes every single last frame you can squeeze out, particularly if you're into overclocking, AMD's Ryzen 9 5900X is the answer on the high-end, and that leading-edge performance will also pay off if you plan to upgrade your GPU soon. Just plan to pay for the privilege.

You'll find that AMD is also often the best option in the mid-range. Unless you're running a tricked-out rig with the fastest GPUs paired with low-resolution high-refresh monitors, you won't miss the slim gaming performance deltas to be had with AMD CPUs, though. At that point, either an AMD or Intel chip will provide a more than acceptable level of gaming performance. However, it's always good to have a little extra gas in the tank for future GPU upgrades, so make sure to examine our closer head-to-head matchups for each price range before you pull the trigger.

In the non-gaming performance battle of AMD vs Intel CPUs, the picture is a lot clearer. AMD's highest-end chips take the outright win in terms of the ultimate performance in threaded productivity and content creation applications. AMD's copious slathering of cores, threads, and cache on its flagship Ryzen 9 5950X and 5900X processors also equates to a big win in the performance-per-dollar category.

Intel's trouble moving forward to denser process nodes has left it behind in the core count race, and now AMD has offerings on both the HEDT and mainstream desktop that Intel simply can't match. Consider this: AMD has a 16-core Ryzen 9 5950X for the mainstream desktop that offers twice the cores and threads as Intel's most powerful Core i9-11900K. Meanwhile, AMD's Ryzen Threadripper 3990X comes with an insane 64 cores and 128 threads for HEDT. That's a 3.5X advantage in core counts over Intel's halo HEDT models.

However, Intel has made things a bit more interesting with its Core i7 and i5 models. These chips go toe-to-toe with AMD's Ryzen 7 and 5 models, offering nearly the same level of performance at lower price points. That makes Intel's sub-$400 Rocket Lake chips incredibly attractive if all you're looking for is performance in heavily threaded content creation applications.

Solid performance in single-threaded work equates to faster performance in all manner of workloads, particularly day-to-day applications that rely on snappy responsiveness from the processor. The Rocket Lake Core i9-11900K has taken the uncontested lead in single-threaded performance across the full spate of our benchmarks, but that's Intel's most expensive mainstream CPU. We see a more pitched battle throughout the rest of both product stacks. Each chip has comparable performance against competing chips in its price range, making this largely a wash for most users. 

Winner: AMD. For professionals on the hunt for performance in content creation and productivity applications, the winner of AMD vs Intel CPUs goes to AMD on the strength of its higher core counts. AMD's lack of integrated graphics on its 8-core and above CPUs (for now) means you'll have to stick with Intel if you want to build a rig without dedicated graphics. Still, most professionals will want a dedicated graphics card regardless.

AMD vs Intel Processor Specifications and Features

AMD has its Ryzen 3, Ryzen 5, Ryzen 7, Ryzen 9, and Threadripper lines, while Intel breaks its offerings up into the Core i3, Core i5, Core i7, Core i9, and Cascade Lake-X families. To compare Intel vs AMD CPUs based on specs and features, we could chart the entire product stacks, but for the sake of brevity, we'll focus on the top chips in the respective families. Be aware that both companies have value options within each tier, but we can get a general sense of the current competitive landscape with these (relatively) short lists. We're using both vendors' recommended pricing and street pricing to give you a sense of the current state of the market.

The high end desktop (HEDT) is the land of creative prosumers with fire-breathing multi-core monsters for just about every need. Intel has long enjoyed the uncontested lead in this segment, but while AMD's first-gen Threadripper lineup disrupted the status quo, the Threadripper 3000 lineup destroyed it.

AMD vs Intel CPUs HEDT Specs and Pricing

Core i9-10980XE$979 / $1,09918 / 363.0 / 4.824.75165W48 Gen3 Quad DDR4-2933

Here we can see that when it comes to AMD vs Intel HEDT CPUs, AMD holds the uncontested lead with 64 cores and 128 threads in its flagship Threadripper 3990X, and the 32- and 24-core Threadripper 3970X and 3960X models cement the overwhelming lead over Intel's chips.

Intel splits its highest-end lineup into two classes, with the Xeon W-3175X and W-3265 dropping into exotic LGA3647 motherboards that carry eye-watering price tags to match the chips' insane pricing. These aren't really enthusiast-class systems, though; think of these as more for the professional workstation market. 

Intel's HEDT lineup truly begins with its 18-core Cascade Lake-X Core i9-10980XE that drops into existing LGA2066 motherboards. The chip is powerful given its price point, but Threadripper's 3.5X advantage in core counts is impossible to beat, so Intel has basically ceded the top of the HEDT stack to AMD. 

You'll get more cores, cache, and faster PCIe 4.0 connectivity with AMD's Threadripper lineup, but they do come with higher price tags befitting such monstrous processors. However, when we boil it down to per-core pricing, or how much you pay for each CPU core, AMD does offer a compelling value story.

In the battle of high-end AMD vs Intel CPUs, AMD's Ryzen 9 and Ryzen 7 families square off against Intel's Core i9 and Core i7 lineup. Again, AMD holds the absolute lead with the 16-core 32-thread Ryzen 9 5950X that sets the high watermark for the mainstream desktop both in terms of core counts and performance—and price, not including a cooler. The 5950X is hard to find in stock, but the Ryzen 9 3950X is equally impressive in most facets. Although it isn't as responsive in single-threaded work or gaming as the 5950X, it's still a good fit for most users.

Intel's eight-core 16-thread Core i9-11900K pales in comparison, but based on pricing, it actually battles the Ryzen 9 5900X. We analyzed these two processors head-to-head in our Ryzen 9 5900X vs Core i9-11900K showdown, with the 5900X coming away with the win.

Here we see that AMD has both the core count and price-per-core advantage in this price bracket. The 11900K does offer impressive gaming performance and fast performance in lightly-threaded workloads, but its power consumption and thermal generation can create a bit of extra cost due to the need for a motherboard with robust power circuitry and a capable cooler.

A similar story plays out in the decidedly more mainstream Ryzen 7 and Core i7 markets. Honestly, these are the chips the majority of gamers should buy. Here AMD's Ryzen 7 5800X matches Intel's Core i7-11700K thread-for-thread, but the Ryzen 7 5800X offers a better blend of performance and future upgradeability.

When it comes to AMD vs Intel mid-range and budget CPUs, the Core i5 and i3 families do battle with AMD's Ryzen 5 and Ryzen 3 processors. This market segment comprises the most substantial portion of AMD and Intel's sales, so pricing and value here are paramount.

AMD's Ryzen 5 5600X matches Intel core-for-core and thread-for-thread to challenge the Core i5-11600K's clock speed and overclocking advantage. The Ryzen 5 5600X vs Core i5-11600K battle is close, but the 5600X takes the edge due to its superior gaming performance. 

AMD also shored up its defenses with a new line of graphics-less $120 Ryzen 3 3300X and $99 Ryzen 3 3100 models, too. Three years ago, Intel's flagship chips cost roughly $350 and came with four cores and eight threads, but now AMD's Ryzen 3 lineup offers the same number of cores and threads for as low as $99. The Ryzen 3 3300X also offers more performance than the 7700K and beats all of Intel's chips in the same price range. Good luck finding one, though, as these chips are rare at retail.

AMD also leans on its Ryzen 5 3600 along with the Ryzen 5 3400G and Ryzen 3 3200G APUs to fend off Intel's Core i5-11500 and i5-11400, but that's a no contest, as you can see in our Intel Core i5-11400 vs AMD Ryzen 5600 showdown. If you're looking for a sub-$200 chip for gaming, Intel wins by a vast margin. That said, AMD's APUs come with potent Vega graphics units that enable low-end gaming across a broad spate of titles. Intel's chips can't hold a candle there—you'll need a discrete GPU if you plan to do any meaningful gaming.

AMD has made its new eight-core 16-thread Ryzen 5000 "Cezanne" APUs available to OEMs and SIs for pre-built systems, but you can't buy them at retail yet. However, there is good news - the Cezanne APUs come to retail in August 2021.

Neither vendor offers integrated graphics units (iGPU) with their HEDT chips. Still, even though Intel sells its graphics-less F-Series chips for a discount, it holds the advantage of having a graphics option across the full breadth of its mainstream product stack.

In contrast, AMD only offers integrated graphics on its APU models, which means you'll need a discrete graphics card (GPU) for any retail chip that has more than four cores (or costs more than ~$150). That's a significant disadvantage for most mainstream users who aren't interested in gaming and eliminates a big chunk of the professional/OEM markets. Intel's iGPUs are mostly useless for gaming but are useful for display and QuickSync purposes, while AMD's iGPUs offer the best gaming experience, hands down. However, AMD's limited selection cuts it out a significant portion of the market.

Winner: AMD. When you compare AMD vs Intel CPU specifications, you can see that AMD offers options with more cores and/or threads, more cache, and robust PCIe 4.0 support for the mid-range and high end. From the top of the HEDT market to the high-end and mid-range, AMD has a capable Ryzen processor that offers more value than comparable Intel models. Conversely, Intel now rules the budget segment, but we could see that change with the arrival of AMD's potent APUs in the coming months. 

AMD vs Intel CPU Power Consumption and Heat

When comparing AMD vs Intel CPU power and heat, the former's 7nm process node makes a huge difference. Power consumption comes as a byproduct of design choices, like lithography and architecture, which we'll discuss below. However, higher power consumption often correlates to more heat generation, so you'll need beefier coolers to offset the heat output of greedier chips.

Intel has improved its 14nm processes to strengthen its power-to-performance ratio by more than 70% in the five long years it's been on the market, but it's no coincidence that Intel's latest chips are known for high power consumption and heat. That's because Intel has had to turn the power dial up further with each generation of chips to provide more performance as it fends off the resurgent AMD. That leads to problems with some stock coolers and also requires robust power delivery on your motherboard. Those factors combine to make Intel a notorious power guzzler.

In contrast, AMD has the benefit of TSMC's 7nm node, which is more efficient than Intel's 14nm. AMD does lose some of that advantage in its Ryzen 3000 and 5000 series processors due to a large central 14nm I/O die that comes as part of the package. Still, in aggregate, AMD's 7nm chips either consume less power or provide much better power-to-performance efficiency. As a result, you'll get more work done per watt of energy consumed, which is a win-win, and AMD's cooling requirements aren't nearly as overbearing.

In fact, the Ryzen 5000 series chips are the most power-efficient desktop PC chips we've ever tested, with the Ryzen 5 5600X offering the best efficiency. 

Winner: AMD. In judging AMD vs Intel CPU performance per watt, It's impossible to overstate the importance of having the densest process node paired with an efficient microarchitecture, and TSMC's 7nm and AMD's Zen 3 are the winning combination. The latest Ryzen processors consume less power on a performance-vs-power basis, which equates to less heat generation. That eases cooling requirements.

AMD vs Intel CPU Overclocking

(Image credit: Intel)

There's no debate when you compare Intel vs AMD CPU overclocking. Intel offers the most overclocking headroom, meaning you can gain more performance over the baseline speed with Intel chips than you can with AMD's Ryzen processors. 

As mentioned, you'll have to pay a premium for Intel's K-Series chips and purchase a pricey Z-Series motherboard, not to mention splurge on a capable aftermarket cooler (preferably liquid), to unlock the best of Intel's overclocking prowess. However, once you have the necessary parts, Intel's chips are relatively easy to push to their max, which often tops out at over 5 GHz on all cores with the 11th-Gen Rocket Lake processors.

Intel doesn't allow full overclocking on B- or H-series motherboards, but it has infused memory overclocking into its B560 and H570 chipsets, and that works with any chip that is compatible with the platform, meaning all 10th-Gen Comet Lake, 11th-Gen Rocket Lake, and 11th-Gen Comet Lake Refresh processors. However, these changes only apply to 500-series models. That can provide a big boost to locked chips, like the Core i5-11400 we recently reviewed.

AMD doesn't have as much room for manual tuning. In fact, the maximum achievable all-core overclocks often fall a few hundred MHz beneath the chips' maximum single-core boost. That means all-core overclocking can actually result in losing performance in lightly-threaded applications, albeit a minor amount.

Part of this disparity stems from AMD's tactic of binning its chips to allow some cores to boost much higher than others. In tandem with AMD's Precision Boost and innovative thread-targeting technique that pegs lightly-threaded workloads to the fastest cores, AMD exposes near-overlocked performance right out of the box. That results in less overclocking headroom.

However, AMD offers its Precision Boost Overdrive, a one-click auto-overclocking feature that will wring some extra performance out of your chip based on its capabilities, your motherboard's power delivery subsystem, and your CPU cooling. AMD's approach provides the best performance possible with your choice of components and is generally hassle-free. In either case, you still won't achieve the high frequencies you'll see with Intel processors (5.0 GHz is still unheard of with an AMD chip without liquid nitrogen cooling), but you do get a free performance boost.

AMD has also vastly improved its memory overclocking capabilities with the Ryzen 5000 series, which comes as a byproduct of the improved fabric overclocking capabilities. That allows AMD memory to clock higher than before while still retaining the low-latency attributes that boost gaming performance. 

Winner: Intel. When it comes to AMD vs Intel CPU overclocking, Team Blue has far more headroom and much higher attainable frequencies. Just be prepared to pay for the privilege – you'll have to buy a K-series processor. Intel has added memory overclocking to the newest B- and H-series motherboards, which is an improvement.

AMD's approach is friendlier to entry-level users, rewarding them with hassle-free overclocking based on their system's capabilities, but you don't gain as much performance. 

AMD vs Intel CPU Lithography

There are a few major underlying technologies that dictate the potency of any chip. The most fundamental rule of processors still holds true: The densest process nodes, provided they have decent power, performance, and area (PPA) characteristics, will often win the battle if paired with a solid microarchitecture. When you judge AMD vs Intel CPUs based on these criteria, AMD has the lead in both lithography and architecture.

But whether or not AMD actually owns the process lead is a topic of debate: Unlike Intel, AMD doesn't produce its processors. Instead, the company designs its processors and then contracts with outside fabs that actually produce the chips. In the case of AMD's current-gen Ryzen processors, the company uses a combination of GlobalFoundries 12nm process and TSMC's 7nm node for its chips, with the latter being the most important.

TSMC's 7nm node is used by the likes of Apple and Huawei, among many others, so it benefits from industry-wide funding and collaborative engineering. The result is what Intel itself calls a superior 7nm process compared to Intel's 10nm and 14nm chips. Intel says its process tech won't achieve parity with the industry again until 2021, and it won't retake leadership until it releases 5nm at an undefined time. 

The benefits of TSMC's 7nm node mean AMD can build cheaper, faster, and denser chips with more cores, and all within a relatively low power consumption envelope. That lends the designs a comfortable lead, provided they're combined with a decent design.

We don't have to focus on Intel's 10nm for this article: Intel has been stuck for six long years on the 14nm process for its desktop chips, which isn't changing any time soon, and its 10nm chips that have debuted in laptops are constrained by the thermal and power limitations of a laptop chassis. 

Regardless of whether AMD can lay claim to developing the 7nm node to wrest the lead from Intel, the company had the foresight to contract with TSMC to gain access to a superior process node technology. That bedrock advantage gives AMD a wonderful silicon canvas to paint its microarchitectures on, a combination that Intel is finding impossible to beat with its 14nm chips.

AMD's only concern is production capacity: While AMD has access to 7nm production, the company can't source enough silicon from TSMC, at least in the near term, to match the power of Intel's captive fabs. That leaves AMD exposed to shortages and potentially restricts market penetration. We've seen the most painful example of that weakness in the wake of AMD's Ryzen 5000 and Radeon 6000 launches. AMD's CPUs and GPUs are often almost impossible to find at retail, and even the company's older models have fallen prey to the shortages. Meanwhile, Intel has plenty of processors available. 

Winner: AMD (TSMC). Intel has been stuck on 14nm for desktop processors for six years. The company has wrung an amazing amount of performance from its aging design through a series of "+" optimizations. Still, those enhancements aren't enough to help Team Blue win the battle of AMD vs Intel CPU process nodes. Intel needs a good 10nm or 7nm desktop chip; the sooner, the better.

Intel vs AMD CPU Architecture

When comparing AMD vs Intel CPUs, we must consider that two design decisions have a big impact on performance, scalability, and performance-per-dollar: Interconnects and microarchitecture.

AMD's Infinity Fabric allows the company to tie together multiple dies into one cohesive processor. Think of this as numerous pieces of a puzzle that come together to form one larger picture. The approach allows the company to use many small dies instead of one large die, and this technique improves yields and reduces cost. It also grants a level of scalability that Intel might not be able to match with its new mesh interconnect inside its HEDT chips, and it undoubtedly takes the lead over Intel's aging ring bus in its desktop processors.

AMD first paired that advantage with its Zen microarchitecture, designed from the ground up for scalability, yielding an explosive 52% increase in instructions per clock (IPC) throughput over AMD's previous-gen 'Bulldozer' chips. The Zen 2 microarchitecture another 15% improvement to IPC. Paired with the 7nm process, AMD lunged forward another (up to) 31% in per-core performance (a mixture of frequency and IPC). Zen 3 brings another 19% jump in IPC, giving AMD its largest single step forward in the post-Bulldozer era. 

The move to the Zen 2 architecture brought AMD's processors to near-parity with Intel's finest in terms of per-core performance. That's largely because Intel is stuck on 14nm, and its architectures are designed specifically for the nodes they are built on. That means promising new Intel microarchitectures can only ride on smaller processes, like 10nm, leaving the company woefully unprepared for its prolonged issues productizing 10nm products.

Zen 3 gave AMD a sizable lead in per-core performance, an incredibly important metric that quantifies the speed of the most important building block in a chip design. Intel's Rocket Lake chips take huge steps forward in per-core performance, leaving both companies on a relatively even playing field in terms of per-core performance.

Rocket Lake features the backported Cypress Cove architecture, Intel's first new microarchitecture for the desktop PC since Skylake arrived back in 2015. Intel says this new architecture is based on Ice Lake's 'Sunny Cove' architecture and also comes with the same performant 12th-gen Intel Xe LP graphics engine found in the Tiger Lake processors. 

"Back-porting" is a method that allows Intel to take a new design built on a smaller process node, in this case, 10nm, and etch it on an older, larger node (in this case, 14nm). The chips come with a new microarchitecture, but they still leverage Intel's 14nm process, although we don't know which revision (14nm++++?). This tactic allows Intel to extend the usability of its 14nm process while moving forward on the architectural front. Still, it is merely a stopgap measure while it readies 10nm for the upcoming Alder Lake processors. You can read more about the Cypress Cove architecture here.

Meanwhile, AMD continues plowing forward. AMD's Zen 3 microarchitecture is refined and powerful - allowing the company to eclipse Intel's performance in single-threaded workloads and gaming for the first time since the days of Athlon 64. Zen 3 truly is a watershed moment for AMD, but the company isn't standing still, with new innovative 3D V-Stack versions of its Zen 3 processors coming next year that bring up to a whopping 192MB of L3 cache in a single processor. 

Winner: AMD. In judging AMD vs Intel CPU architecture, it's clear that one brand is moving faster. Intel rode its Skylake microarchitecture since 2015, and while Cypress Cove provides impressive performance uplift, it comes as a backported design on an older process node. That's far from ideal and often results in untenable levels of power consumption. AMD, fueled by rapid advances in its designs while Intel leans on a six-year-old process node, has taken the lead in many of the most important aspects of chip design.

AMD vs Intel CPU Drivers and Software

When we look at AMD vs Intel CPU software support, Team Blue has a stronger reputation. AMD has been beset by issues with its CPU chipset drivers and graphics drivers of late, a natural byproduct of its limited resources compared to its much-larger rivals. Intel isn't without its missteps on the driver front, but its reputation for stability helped earn it the top spot in the processor market, particularly with OEMs.

In terms of its established products, Intel's graphics drivers have become much better lately as the company ramps up to bring its dedicated Xe Graphics cards to market. Day-zero game drivers have become the norm for the chip producer, which by virtue of its integrated graphics on its chips, is the world's largest graphics vendor with an install base of over a billion screens—that's a billion slow screens, but who's counting? (Answer: Every PC gamer out there.)

You might be a little more cautious when approaching Intel's more exotic solutions, though. In the past, the company has developed innovative new products that have been relegated to the dustbin of history due to pricing and market forces, and long-term support for those products might not always be clear cut.

AMD still has its work cut out for it. The company has had several issues with BIOS releases that failed to expose its chips' full performance, though AMD has mostly solved those issues after a long string of updates. As a side effect of being the smaller challenger, AMD also faces a daunting challenge in offsetting the industry's incessant optimization for Intel's architectures above all others.

Upsetting the semiconductor industry is hard, particularly when you're fighting an entrenched and much-larger rival, and sometimes things get broken when you're redefining an industry. In AMD's case, those broken things consist of operating systems and applications that weren't tuned to extract the full performance of its fledgling first-gen Zen architecture, let alone the core-heavy designs of Zen 2 and Zen 3. 

Winner: Intel wins the battle of AMD vs Intel CPU drivers and software. Over the last year, Intel has addressed its laggardly driver updates for its integrated graphics, and the company has an army of software developers at its disposal that help ensure its products get relatively timely support with the latest software. A decade of dominance also finds most software developers optimizing almost exclusively for Intel architectures. AMD has made amazing progress convincing the developer ecosystem to optimize for its radical new Zen architectures. However, there's still plenty of work to be done as the company moves forward.

AMD vs Intel CPU Security

The last few years have found security researchers poking and prodding at the speculative execution engine that's one of the key performance-boosting features behind all modern chips. The resulting research has spawned an almost never-ending onslaught of new vulnerabilities that threaten the safety of your system and private data. Unfortunately, these types of vulnerabilities are incredibly dangerous because they are undetectable—these tactics steal data by using the processor exactly as it was designed; thus, they are undetectable by any known anti-virus program.

The rash of fixes required to plug these holes also continues to grow, and many of them result in reduced performance. That's particularly painful for Intel because it suffers from far more of these vulnerabilities than other vendors. 

Intel currently has 242 publicly disclosed vulnerabilities, while AMD has only 16. That's a 15:1 difference in AMD's favor. It's hard to ascertain if these limited discoveries in AMD processors are due to a security-first approach to hardened processor design, or if researchers and attackers merely focus on Intel's processors due to their commanding market share: Attackers almost always focus on the broadest cross-section possible. We see a similar trend with malware being designed for Windows systems, by far the predominant desktop OS, much more frequently than MacOS, though that does appear to be changing.

Regardless, right now, AMD has had far fewer security holes to plug, and it made a few targeted in-silicon fixes for its Ryzen 5000 processors, thus lowering its exposure to the vulnerabilities. 

We've seen some of the fixes drop performance more than two or three architecture updates on Intel, which is particularly painful, and there's no end to these exploits in sight.

Winner: AMD. The gap in AMD vs Intel CPU security is just too large to ignore. As things stand, Intel is susceptible to far more vulnerabilities than AMD. That could change as AMD gains market share, and security researchers increasingly turn their microscopes on its architecture. For now, Intel processors require far more mitigations to improve their security standing. These mitigations often come with a performance penalty, and Intel tends to suffer larger performance losses than the few fixes we've seen from AMD, granting Team Red the win.

    I disagree with the overclocking section, and I would say it's either a tie or a win for AMD.

    Just because Intel sets base speeds so much lower than actually achievable speeds so they can slap on a ridiculously low TDP doesn't mean they're better overclockers, it just means Intel wants a low number to mislead people as to their efficiency.

    With AMD and Intel having all core boost speeds within a couple hundred megahertz, depending on cooling, of their single core boosts, and with both able to be manually overclocked to or past their all core boost clocks, often using less voltage than the boost voltage, it's pretty even there.

    AMD currently makes the best processor for the value. You can buy a Ryzen 5 1600 on Amazon right now for $85 brand new, which is a 6 core 12 thread processor and fully unlocked. The core i3-9100f for comparison, is $10 less than the 1600 on Amazon, but only has 4 cores, 4 threads.

    For the value of the Ryzen 5 1600 and with games and programs using more cores, it's obvious the Ryzen series is a much better value than Intel. However, with Intel finally realizing the competition from AMD, they will be making better and more affordable CPU's for consumers.

    In the end, competition is great for us!

    intel is stuck where amd was with its fx series of chips. nothing new to offer, so you just keep cranking up the spped/power and relabel it as something new.

    at least what intel is doing it with started out as a much better cpu than the fx series ever was.

    but i do agree that their listed speeds and power consumption is downright misleading. to claim "stock" speeds so low just to claim low power usage is outright fraud. they don't need to list them at 5 ghz but obviously closer in speed and power the average user can expect would go along way to not be so misleading.

    Intel actually has another reason for what they do with their low base speeds. Ever got an i5 that just wouldn't over clock? If you do one of the cores will crash? They get to sell a certain percentage of silicon this way that otherwise would go to a lower product stack or the garbage bin.

    I understand the reasoning of why all reviews are done on a clean install. Only way to compare apples to apples. However, no one games or does anything this way. So, a useless case scenario where someone is going to spend thousands on a top CPU, GPU, Whole system. And pair it with a 1080p monitor. And a clean install everytime they fire up a game, is misleading at best. But, let's assume this system exists. This gamer will be watching youtube and twitch, using discord, probably office, a HW monitoring suite, steam client, maybe streaming his awesomeness. etc. Not to mention all the other crap and registry stuff that happens to windows PC's over time. What happens to the numbers on a dirty system? Impossible to compare apples to apples in this scenario. But, an educated guess says that Ryzen with its multitasking advantages would really shine while intels CPU's would bog down. Taking away Intels one advantage it has left. Other than the one that matters most of all of course. Name recognition, and an unlimited horde of fanboys.
