CPU Comparison
Intel Core i3-10100 vs Intel Core i3-10300
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.
The 8MB cache provides a noticeable uplift in applications that are sensitive to L3 cache size compared to 6MB retail parts.
Gaming
Can handle 1080p gaming with a mid-range GPU, though it will bottleneck newer titles compared to 12th-gen alternatives.
Better than a retail i3-10100 due to the extra cache, but OEM PCs with this chip rarely include a capable dedicated GPU.
Virtualization
Can run a single light VM, but 4 cores and 8 threads limit serious virtualization use.
The extra cache helps in VM context switching, but 8 threads is still a hard limit.
Efficiency
The 14nm process is less power-efficient than modern 10nm alternatives, drawing more power for less performance.
The 90W PL2 is inefficient for a 4-core chip, but OEMs typically lock this down, resulting in standard 65W operation.
Specialized Performance
AI / ML
- No AI acceleration hardware
- Lacks AVX-512 support found on mobile Tiger Lake chips
- Not suitable for AI workloads
- No dedicated AI hardware
- Extra cache does not significantly impact AI inference
Content Creation
Gaming
- Playable in older and e-sports titles with a dedicated GPU
- Will bottleneck GPUs above the GTX 1660 Super / RX 580 tier in modern games
- Lacks the single-thread speed of newer architectures
- Rarely found in systems with adequate GPUs
- Cache uplift helps minimally in gaming compared to retail i3s
- UHD 630 is not suitable for 3D gaming

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The i3-10100 was a solid budget chip in 2020 thanks to the return of Hyper-Threading, but it is now outdated, held back by PCIe 3.0, DDR4-2666 limits, and an aging 14nm process.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 However, for any new build, it is obsolete.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 OEM-only chip that is slightly better than its retail counterparts thanks to 8MB of L3 cache, though its 90W PL2 is an oddity for a 4-core part that most OEM coolers cannot handle.
Best for: Pulling one from a scrapped OEM PC to use in a cheap LGA 1200 build, taking advantage of the 8MB cache.
