RAM Benchmark Hierarchy: Fastest DDR5, DDR4 Memory Kits for AMD and Intel

RAM Benchmark Hierarchy
RAM Benchmark Hierarchy (Image credit: Tom's Hardware)

Consumers often overlook RAM (Random Access Memory), but our RAM benchmark hierarchy will help you find the fastest DDR5 and DDR4 memory kit for your system. Memory is one of the most critical pieces of hardware of any system, after all. The right or the wrong memory kit significantly impacts your system's overall performance in gaming, productivity, and (if you don't have enough of it) general sluggishness. Of course, you can always reference our Best RAM list to find the best deals on memory.

Companies regularly release new memory kits with different speeds, timings, capacities, and ranks, making sifting through seemingly endless models surprisingly time-consuming. Our RAM benchmark hierarchy aims to provide you with a simple database that ranks the best memory kits based on pure performance.

We use a geometric mean of our memory benchmarking results to keep the ranking objective and discard the intangibles, like aesthetics and overclocking headroom. We've got those details in the individual RAM reviews. Furthermore, we suspect many of you would value performance over anything else. However, the geometric means don't always tell the whole story: If you're looking for performance in a specific workload or gaming, we recommend looking at the full review of the memory kit you have in mind.

The score results originate from the geometric mean from our RAM benchmark suite consisting of scripted and real-world tests. Our tests include Microsoft Office, Adobe Photoshop, Adobe Premiere, Adobe Lightroom, Cinebench R23, Corona benchmark, 7-Zip compression and decompression, Handbrake x264 and x265 conversion, LuxMark, and Y-Cruncher.

For simplicity, we've separated the memory kits into different categories according to their densities. Then, we ranked the memory kits for each capacity from best to worst for both Intel and AMD systems.

The score on our hierarchy may differ slightly from the geometric mean in the individual review. The discrepancy is because we strive to provide you with results on the most recent and relevant Intel and AMD platforms. Keeping the metrics in the table as up-to-date as possible involves retesting every single memory kit. We rest when there's been a substantial change in either of our test systems, such as a new processor, motherboard, or graphics card (or even new firmware revisions), to name a few.

Memory pricing is very volatile. We've restrained ourselves from providing a price-to-performance value since it would only capture the pricing for one static moment in time, and memory pricing fluctuates far too much. So while you can see up-to-date pricing listed in each table below, the performance measurements don't take that pricing into account. 

If you're undecided between two particular kits, it's easy to evaluate the options on your own by dividing the real-time pricing by the geometric mean. You'll want the lowest value possible, as a lower number represents more bang for your buck.

Processors and Official Supported Memory Frequency

Once upon a time, the memory controller resided on the motherboard. As processors and motherboards evolved, chipmakers eventually moved the memory controller onto the chips. Therefore, Intel and AMD specify the official supported memory frequency supported on each generation of their processors. Unless you have an excellent sample, drifting far away from the supported frequency will require manual tweaking to get the memory to play nice with your processor. For the best plug-n-play experience, you should pick up a memory kit that doesn't surpass the supported frequency.

There are two essential things to consider if you want to run memory faster than the official specification for your processor. For starters, the quality of your processor's IMC (integrated memory controller) determines if it can handle high-speed memory. Unfortunately, since no two processors are equal, and you can't judge a chip's IMC until you test it, you're at the mercy of the silicon lottery.

Secondly, you need to ensure that the motherboard supports the frequency of the memory kit that you have in mind. Again, a quick trip to your motherboard's user manual or product page should give you the information that you need. Furthermore, the motherboard's memory QVL (Qualified Vendors List) is very helpful as it'll tell you whether a specific memory kit has been tested and validated on the motherboard. But remember that your chip's IMC still plays a more prominent role.

If you're unsure of the memory frequency that your processor supports, we've provided the different standards for the last few generations of AMD and Intel processors.

AMD's existing Zen 2 and Zen 3 processors arrive with native support for DDR4-3200 memory modules right out of the box. As you are well aware, Ryzen 3000 puts up the best performance when the Infinity Fabric clock (FCLK) is in sync with the memory clock (MCLK) in a 1:1 ratio. Therefore, it's vital to remember that asynchronous operation introduces a latency penalty. Most Ryzen 3000 processors can operate with an FCLK up to 1,800 MHz or DDR4-3600. 

Ryzen 5000 follows the same guidelines in regards to the FCLK and MCLK. However, the excellent samples can support a 2,000 MHz FCLK, which opens the door to leverage DDR4-4000 memory without any performance hit. For more information on the impact of memory frequency, capacity, and ranks on Ryzen 5000's performance, see our latest Ryzen 5000 RAM guide.

AMD's Zen 4 processors will come with DDR5 support. In addition, the chipmaker will release the Ryzen 7000 (Raphael) chips in the second half of 2022.

Intel has launched the company's brand-new 12th Generation Alder Lake processors. These are the first consumer chips to support DDR5 memory and the PCIe 5.0 interface. However, Alder Lake is also compatible with DDR4 memory, and it'll depend on the motherboard manufacturer to pick the best format for their products.

Intel reworked how the memory works on Rocket Lake. The chipmaker introduced gear ratios with the memory controller and memory frequency, similar to how AMD's FCLK works. For example, gear 1 finds both running in a 1:1 balance, while Gear 2 runs the memory controller at half speed (0.5:1). Alder Lake retains this same mechanic.

Alder Lake arrives with native compatibility with DDR4-3200 and DDR5-4800. Intel 600-series motherboards will either come with DDR4 or DDR5 slots but not both due to the radical change with DDR5's voltage regulation. Alder Lake processors run DDR5 in Gear 2 mode and DDR4-3200 in Gear 1 mode by default. Nonetheless, some rare Alder Lake samples can effectively run up to DDR4-4000 in Gear 1, equivalent to the best Zen 3 chips.

DDR5 memory support on Alder Lake depends on the number of populated memory slots. On a dual-slot motherboard, Alder Lake supports DDR5-4800 regardless of the configuration. However, DDR5-4400 is the maximum data rate when you fill two slots on standard motherboards with four memory slots. Populating the four slots with single-rank or dual-rank memory drops support down to DDR5-4000 and DDR5-3600, respectively.

Finding Deals on the Best RAM

The latest TrendForce report estimates that DRAM pricing will decrease between 3% to 8% in the fourth quarter of this year. According to the firm's investigation, DRAM suppliers have enough stock for their clients. However, the latter has a surplus of inventory, so the demand is more diminutive. Nevertheless, the news is music to consumers' ears since pricing for memory kits should see a significant drop in the upcoming months.

Whether you're shopping for a memory kit that's on our list of Best RAM or one that's not on the list, you may find savings by checking out the latest Newegg promo codes, Best Buy promo codes, and Micro Center coupon codes.

    It's assuring to see that (for AMD) the very best is only 1.9% uplift over the basic 3,200 MHz @ 16-18-18-38. No need to spend more money there.

    They sort of did. Today's 2x16GB kits are typically going to provide four ranks, while the 2x8GB kits will typically provide two. That's why all of the 2x16GB kits outperformed the 2x8GB kits, with the possible exception of that one DDR4-5100 kit that managed to hold it's own against a few of them in the AMD test system. But at $900, that 5100 kit is kind of nonsensical considering it was still outperformed by some 2x16GB kits of DDR4-3600 at a fraction of the price. Going with 32GB for four ranks (whether 2x16GB or 4x8GB) will tend to benefit performance more than paying a big premium for just 16GB of enthusiast-level RAM, and if one is planning to keep their system around for a number of years, the added capacity will likely provide even more benefit down the line.

    Tom's had an article pointing this out shortly after the Ryzen 3000 series launched...

    Yes, this article basically reinforces what we already know, spending money on expensive ram doesnt make any sense, unless you have unlimited budget.

    Yes, someone has also pointed out that 4 ranks of ram is faster than 2. But, the gains are very small as well. You are better off using the budget for more cores or faster gpu.

    Yes, we do know 4 sticks is faster. But it cost more too...so its down to your budget. If you spare budget, its fine. If you, then no.

    The video compares 4x 8GB single rack against 2x8G single rank, 2x16gb Dual rank dimms have the same improvement as 4x8GB single rank, it's the total number of ranks (4) that matters.

    They missed the best memory kit for 5000 series AMD cpu Gskilll 3800 CL14 32GB (2x1GB) dual rank F4-3800C14D-32GTZN-G.SKILL International Enterprise Co., Ltd.

    I read somewhere that 1.2V is generally considered the upper limit of safe SoC voltages, particularly on Ryzen 3000CPUs.
    SOC voltage - system on a chip voltage; responsible for the voltage related to the memory controller.
    Limit: up to 1.2 V.

    DRAM boot voltage - voltage at which memory training takes place at system start-up.
    Limit: up to 1.45–1.50 V.

    VDDP voltage - voltage for the transistor that sets memory contents.
    Limit: up to 1.1 V.

    1.42V will cause degradation of the CPU
    1.38V should be max for 24/7 - 1.35V would be safer

    Why doesn't the article mention this, that higher voltage on high speed ram causes degradation of the CPU?
    All overclocking is risky business when it comes to higher than recommended voltage.

    Where is DDR5 section ?
    What is the fastest / best DDR5 Kit ?
    The title suggest that this articles also cover DDR5

    Probably too early to tell, need more DIMMs and motherboards to actually test with.
