Intel Core i5-6600K vs Intel Core i3-6100

Last updated:
The Intel Core i5-6600K is a 6th generation (Skylake S architecture) desktop processor from Intel, manufactured using the 14 nm process and aimed at mainstream users, gamers, and overclocking enthusiasts.

It features four physical cores, four threads, and 6 MB of Level 3 Cache, complemented by PCIe 3.0, 34 GB/s memory bandwidth, and the integrated Intel HD Graphics 530. In performance tests, it shows significantly higher single-core and multi-core performance, making it ideal for demanding applications and gaming.

Its TDP is 91 watts, which means higher power consumption. Priced higher, it offered compelling performance and flexibility. It is recommended for users with high performance demands. The Intel Core i3-6100 is also a 14 nm Skylake S 6th generation desktop processor from Intel, designed for budget-conscious systems and basic office or home tasks.

It has two physical cores and four threads thanks to Hyper-Threading, accompanied by 3 MB of Level 3 Cache. Like the Intel Core i5-6600K, it offers PCIe 3.0, 34 GB/s memory bandwidth, and the Intel HD Graphics 530. Its single-core and multi-core performance is solid for everyday tasks, but noticeably lower than that of the Intel Core i5-6600K.

For gaming, it is more suitable for less demanding titles. With a low TDP of 51 watts, it is very energy-efficient, enabling cool and quiet systems. It was a more cost-effective option with good price/performance ratio for its area of use and is recommended for basic applications.
