Intel Core i7-6700K

Intel 6700K

The Intel Core i7-6700K is a high-end quad-core desktop processor based on the Skylake architecture, which was announced in August 2015. The CPU, which is manufactured in a 14 nm process, runs at 4.0 up to 4.2 GHz (2 cores: 4.0 GHz, 3 cores: 4.0 GHz, 4 cores: 4.0 GHz) and can execute up to 8 threads simultaneously thanks to Hyperthreading. Being a so called "K"-model, the Core i7-6700K has a free multiplier and can be easily overclocked. 

Performance

Even though the Core i7-6700K has a slightly lower clock than the old i7-4790K (4.0 GHz - 4.4 GHz), the performance is slightly better compared to the Haswell predecessor. Depending on the application, the per-MHz performance was increased by roughly 5-10 %. Even the most demanding applications and games are no problem for the high-end CPU.

Graphics

Graphics are handled by the integrated Intel HD Graphics 530 with 24 EUs (Execution Units), which is clocked at 350 - 1150 MHz. Compared to the HD Graphics 4600 (Haswell, 20 EUs), the performance is increased by around 25 percent. The overall GPU performance is still low-end, so modern games can, if at all, only be played smoothly with low settings. 

Power Consumption

The TDP was slightly raised from 88 to 91 Watts compared to the predecessor.
