Intel's four-core eight-thread Core i3-12100 comes with an incredibly competitive $129 price tag that earns a spot on our list of best CPUs for gaming and Best Cheap CPUs as Intel finally addresses what has become the most ignored part of the PC market — the sub-$200 segment. That's not to mention that the chip also comes as a $104 F-series Core i3-12100F that Intel ships with deactivated integrated graphics for $25 less than the full-featured model. In fact, with no clear current-gen competitor from AMD and stellar performance for its price point, the Core i3-12100 easily leads our CPU benchmark hierarchy in the $105 to $130 bracket.

Intel refreshed its Comet Lake Core i3 lineup when it released its 11th-Gen Rocket Lake chips in 2020, but those models didn't come with a new architecture or any meaningful performance improvements. Rather, they came as refreshed 10th-Gen models with a paltry 100 MHz clock speed increase. Not that it mattered — given the realities of the chip shortages, we rarely saw those chips at retail anyway.

Speaking of chips that don't really exist, AMD's last budget model came as the incredibly impressive Ryzen 3 3300X that landed back in 2020. The quad-core 3300X brought an unheard-of level of performance for a $120 chip, promising new levels of gaming performance for budget builds. Unfortunately, that didn't come to fruition as the chip was a ghost and never appeared in any meaningful volume at retail.

Things haven't improved in the interim, either. AMD abandoned the sub-$200 market when it launched its Ryzen 5000 processors, leaving its older 3000-series processors to hold the line. However, as you'll see in our benchmarks below, they aren't relevant. AMD's lowest point of entry into its Zen 3-powered Ryzen 5000 series comes in the form of the $259 Ryzen 5 5600G. At twice the price of the 12100, it's a non-factor for lower-end gaming rigs unless you plan to use integrated graphics.

That leaves Intel unchecked in the budget segment, adding to the company's newfound dominance with the Alder Lake chips that even outperform more expensive Ryzen 5000 chips. Intel's advantages also extend to the motherboard ecosystem too, with B660 and H610 motherboards providing a great pairing for the Core i3-12100. So even though these boards do cost more than we're accustomed to for the lowest-end models, they provide plenty of connectivity for budget systems.

Alder Lake's performance advantages come even without its support for DDR5 memory and PCIe 5.0 interfaces (both of which Intel brought to market first). As such, you can use standard DDR4 memory and PCIe 4.0 devices and still have superior performance and connectivity options over AMD's aging AM4 platform. There are also plenty of B- and H-series boards that leverage less-expensive DDR4 memory, which is a saving grace given the ongoing DDR5 shortages.

Alder Lake also brings another innovation — the hybrid x86 design. The higher-end Alder Lake chips have big and fast Performance cores (P-cores) for latency-sensitive work paired with clusters of small and powerful Efficiency cores (E-cores) that chew through background processes. The Golden Cove architecture powers the 'big' P-cores, while the 'little' E-cores come with the Gracemont architecture.

However, the Core i3-12100 doesn't have a hybrid architecture, instead coming with a more traditional design with only four Golden Cove P-Cores active. That means this four-core eight-thread processor doesn't need Intel's new Windows 11-exclusive Thread Director technology to place workloads on the correct cores. As a result, unlike Intel's hybrid models, the 12100 is just as potent in Windows 10 as it is in Windows 11.

As you'll see in our benchmarks below, the Core i3-12100 doesn't have a similarly-priced competitor from AMD. However, despite a total lack of competition, it still brings impressive generational performance gains to the table. In fact, in 1080p gaming, the $129 Core i3-12100 delivers 88% of the $299 Core i5-12400's performance, but for 56% less cash. The Core i3-12100 also trails the previous-gen $262 Core i5-11600K by a mere 3% in gaming, but at half the price. 

Overall, the quad-core i3-12100's potent combination of price, performance, and improved stock cooler dominates the $100 to $130 price range while punching up against more expensive competitors. 

Intel Alder Lake-S Core i3-12100 Specifications and Pricing

We have deep-dive coverage of the Alder Lake design and microarchitectures here, along with a broader overview in our Alder Lake all we know article. Additionally, Intel now assigns a Processor Base Power (PBP) spec instead of using the 'TDP' (Thermal Design Point) nomenclature. The company also added a secondary Maximum Turbo Power (MTP) value to represent the highest power level during boost activity. You can read more about that here.

Intel fabs Alder Lake on the 'Intel 7' process. We previously knew this 'Intel 7' manufacturing tech as 10nm Enhanced SuperFin, but Intel recently renamed its process nodes to match industry nomenclature. Technically, 'Intel 7' is the second generation of Intel's 10nm process, but it's a first for desktop PCs.

All Alder Lake chips support DDR4-3200 or up to DDR5-4800 memory, but caveats apply. PCIe support will vary by motherboard, but Alder Lake chips expose up to 16 lanes of PCIe 5.0 (technically for storage and graphics only, no networking devices) and an additional four lanes of PCIe 4.0 from the chip for M.2 storage. Intel's Alder Lake drops into Socket 1700 motherboards from the 600-series, including Z690, H670, B660, and H610.

The Core i3-12100 comes with a 60W PBP (base) and 89W MTP (peak) power rating. The chip clocks in with a 3.3 GHz base and boosts up to 4.3 GHz. It also comes with 12 MB of L3 cache.

The Core i3-12100 is a locked chip, meaning it isn't overclockable. However, Intel supports memory overclocking on Z690, H670 and B660 motherboards (Z690 doesn't make sense for this class of chip, though). Manipulating the power limits serves as a quasi-overclock that can eke out some additional performance in some gaming and threaded work, but you don't get much of a benefit with chips this far down on the low end.

Intel has revamped its stock air coolers with Alder Lake. These coolers are designed to address two major deficiencies with Intel’s stock coolers: Thermal dissipation limitations and aesthetics. AMD’s stock coolers have long beat Intel in both of these departments, so this is a sorely-needed upgrade. The Core i3-1100 ships with the Laminar RM1 cooler that comes without RGB lighting but has a decorative blue plastic ring lining the fin stack. Intel rates this cooler for ‘quiet performance’ at 3.9 BA.

We tested with both the stock heatsink and a Corsair H115i watercooler to gauge the strength of the air cooler. We didn't measure any meaningful difference between the two, so as long as you're not experiencing severe chip bowing issues, you can use the stock cooler without worry.

The standard Core i3-12100 comes with the UHD Graphics 730 engine with 24 EUs. The engine runs at 300/1400 MHz base/boost frequencies. If you're looking to save some coin, the graphics-less Core i3-12100 comes with a $25 price reduction and has the same specs as the 12100, which is incredibly attractive if you plan on using a discrete graphics card. The only difference between the standard 12100 and the 12100F is that the latter has a 58W PBP rating, so performance is identical with both models. Notably, going with the 12100F means you will lose Quick Sync capabilities and the iGPU fallback that you can use for troubleshooting in the event of an issue with a discrete GPU.

    My guess is it was reviewed before newer bios came out.

    This chart makes me think how good of a value 5600X has been all this time. Even now it performs very solidly against the latest from Intel.

    The only thing is that i3-12100 should be compared against i5-10400 (if comparing current alternatives from previous generations) instead of i3-10100, as the i5 is the one that is similarly priced and the older i3 has much lower price. Basicaly the same 30% lower price for the same performance drop.

    5600x was getting sold for over $300 a year ago. It is now getting matched by a $169 12400F. Doesn’t seem to be a good value for “all the time” when a $300 class CPU becomes a sub $170 class CPU within a year. There wasn’t much inflation when 5600X launched for AMD to jack up the Ryzen 5 price by $50. Consumer mentality like yours can make them increase the price again this year by another $50 or may even be more since now there is an inflation to blame as well.

    AMD was a little too proud of their accomplishment in Ryzen 5000 at launch for sure.

    Can we appreciate that 4 cores is still relevant in offline/single-player gaming though!

    too proud? They overcame their only rival for the first time in a decade and did so quite handily.
    I'd say they were right on the money........
