Intel Core i7-6700K vs Intel Core i3-8100

The Intel Core i7-6700K (codename Skylake S) was introduced by Intel in 2015 as a high-end processor for enthusiasts and overclockers.

Manufactured using the 14nm process, it features 4 cores and 8 threads (Hyper-Threading). Its integrated graphics unit is the Intel HD Graphics 530, the Level 3 cache is 8 MB, and the maximum memory bandwidth is 34 GB/s. In performance comparisons, it offers over 10 percent higher single-core performance and significantly higher multi-core performance than the Intel Core i3-8100, making it more advantageous for demanding applications and gaming.

Its TDP is 91W. The Intel Core i3-8100 (codename Coffee Lake S) appeared in 2017 as a mainstream processor for everyday tasks. It is also manufactured using the 14nm process but offers 4 cores and 4 threads without Hyper-Threading. Equipped with Intel UHD Graphics 630, a 6 MB Level 3 cache, and a maximum memory bandwidth of 38 GB/s, it is more energy-efficient with a TDP of 65W.

Although it has a newer architecture, its single-core and multi-core performance is below that of the Intel Core i7-6700K. Currently, both processors are mainly available on the used market. For maximum computing power in games and demanding applications, the Intel Core i7-6700K is the superior choice.

The Intel Core i3-8100 is a good option for standard tasks and energy-efficient systems.
