CPU Comparison
Intel Core i7-6700 vs Intel Core i3-10100
A side-by-side comparison of specs, performance and value. The Intel Core i7-6700 is a mainstream quad-core desktop processor that served as the backbone of the 6th Generation Skylake lineup. Released in 2015, it brought incremental but meaningful improvements over the previous Haswell generation, including higher IPC, improved integrated graphics, and the introduction of DDR4 memory support to the mainstream market. Operating at a base clock of 3.4 GHz and boosting up to 4.0 GHz, it delivered strong single-threaded performance ideal for gaming and everyday productivity. With four cores and eight threads, it handled the multitasking demands of the era effectively. The 65-watt TDP ensured it ran efficiently and coolly, making it a staple in millions of office and home PCs worldwide. The inclusion of Intel HD Graphics 530 allowed for smooth 4K video playback and basic media tasks without requiring a discrete GPU, cementing its reputation as a versatile, do-it-all processor for mainstream users.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles office workloads and multitasking without issues.
Office work and web browsing are fast, but heavy multitasking will show the limitations of 4 cores.
Gaming
Good for 60fps gaming with a discrete GPU, but struggles with modern high-refresh titles.
Can handle 1080p gaming with a mid-range GPU, though it will bottleneck newer titles compared to 12th-gen alternatives.
Virtualization
Capable of running 1-2 light VMs.
Can run a single light VM, but 4 cores and 8 threads limit serious virtualization use.
Efficiency
Highly efficient 65W design.
The 14nm process is less power-efficient than modern 10nm alternatives, drawing more power for less performance.

Our Verdict on Each
A reliable and efficient quad-core CPU that was the gold standard for mainstream desktop computing in 2015, still capable of basic tasks today.
Best for: Upgrading an older LGA 1151 system for budget 1080p gaming.
Read the full reviewThe i3-10100 was a solid budget chip in 2020 thanks to the return of Hyper-Threading, but it is now outdated, held back by PCIe 3.0, DDR4-2666 limits, and an aging 14nm process.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.
