CPU Comparison
Intel Core i3-10100 vs Intel Core i3-12100
A side-by-side comparison of specs, performance and value. The Intel Core i3-10100 is a 4-core, 8-thread desktop processor built on the 14nm Comet Lake architecture, bringing Hyper-Threading back to the desktop i3 tier with UHD Graphics 630 and a 65 W TDP.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Office work and web browsing are fast, but heavy multitasking will show the limitations of 4 cores.
Handles everyday office tasks and web applications with ease, but heavy multitasking will expose the 4-core limitation.
Gaming
Can handle 1080p gaming with a mid-range GPU, though it will bottleneck newer titles compared to 12th-gen alternatives.
Delivers playable 1080p frame rates in esports and older AAA titles when paired with a mid-range GPU, though 4 cores limit performance in modern CPU-heavy games.
Virtualization
Can run a single light VM, but 4 cores and 8 threads limit serious virtualization use.
Can run a single lightweight virtual machine, but lacks the core count for serious virtualization workloads.
Efficiency
The 14nm process is less power-efficient than modern 10nm alternatives, drawing more power for less performance.
Very power-efficient for a desktop processor, drawing little power at idle and scaling linearly under load.

Our Verdict on Each
The i3-10100 was a solid budget chip in 2020 thanks to the return of Hyper-Threading, but it is now outdated, held back by PCIe 3.0, DDR4-2666 limits, and an aging 14nm process.
Best for: The i3-10100 only makes sense today if you are upgrading an existing LGA 1200 system on an extremely tight budget and can find the chip used for a very low price. It can also be considered if you are repairing an office PC that already uses an LGA 1200 motherboard and you just need a drop-in replacement. However, for any new build, it is obsolete. The i3-12100 offers a massive architectural leap for a similar price, featuring PCIe 5.0, DDR5 support, and dramatically higher single-core performance. Avoid building a new system around the 10100 entirely.
Read the full reviewThe i3-12100 delivers exceptional single-threaded performance for its $122 price point, complete with an iGPU and a stock cooler, making it one of the most well-rounded budget desktop processors Intel has ever produced.
Best for: Buy the i3-12100 if you are building a budget desktop PC and want the peace of mind of having integrated graphics as a fallback, or if you do not plan to install a dedicated GPU. At its current street price, it is an excellent choice for office PCs, student workstations, and entry-level gaming rigs paired with a mid-range graphics card like the GTX 1660 Super or RX 6600. Avoid it only if you are certain you will never need the iGPU, as the 12100F offers identical CPU performance for less money.
