CPU Comparison
Intel Core i3-10100 vs Intel Core i3-10320
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 office suites and web apps well, but the 65W PL1 will cause throttling in long-running Excel macros or heavy multitasking.
Gaming
Can handle 1080p gaming with a mid-range GPU, though it will bottleneck newer titles compared to 12th-gen alternatives.
Requires a discrete GPU for gaming. The CPU itself can handle budget GPUs without severe bottlenecking at 1080p.
Virtualization
Can run a single light VM, but 4 cores and 8 threads limit serious virtualization use.
4 cores and 8 threads can run a couple of light virtual machines, but it is not ideal for dedicated lab environments.
Efficiency
The 14nm process is less power-efficient than modern 10nm alternatives, drawing more power for less performance.
The 14nm process shows its age; newer Ryzen 3 parts offer significantly better performance per watt.

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The i3-10100 was a solid budget chip in 2020 thanks to the return of Hyper-Threading, but it is now outdated, held back by PCIe 3.0, DDR4-2666 limits, and an aging 14nm process.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 However, for any new build, it is obsolete.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 reviewA capable 4-core processor for basic computing, but its OEM exclusivity and confusing 91W/65W power spec make it irrelevant for custom builders.
Best for: The Intel Core i3-10320 is not a processor you should actively seek out to build a new PC, primarily because it was never intended for the retail market. If you are upgrading an existing OEM desktop that currently houses this chip, it is generally not worth the investment to swap it out for an i5 or i7 due to motherboard BIOS restrictions common in pre-built systems. However, if you are purchasing a used office PC on the cheap that contains the i3-10320, it remains surprisingly capable for everyday tasks. Its 4 cores and 8 threads, combined with a 4.6 GHz boost clock, handle web browsing, office applications, and 1080p media consumption without breaking a sweat. Just be aware of the 65W PL1 limit, which may throttle sustained workloads, and the DDR4-2666 memory speed cap, which slightly bottlenecks the integrated UHD 630 graphics. Avoid it for any serious gaming or content creation.
