The i5-7600K targets high end gamers, it sits just behind the flagship i7-7700K in Intel’s Kaby Lake lineup. The 7600K will likely be the most popular gaming CPU of 2017 (some competition from AMD’s upcoming Zen/Ryzen CPUs, would be very welcome). Comparing the 7600K and 6600K shows that the two processors are very closely matched and comparing the 7600K vs the hyper-threaded 7700K highlights the relative strength of the 7700K for workstation performance. There are no significant architectural differences between Kaby Lake and Skylake so, when fully overclocked, the two generations should perform similarly but Kaby Lake offers faster base clocks, improved speed shift technology which helps CPU responsiveness, and better integrated graphics[Jan '17 CPUPro]


The Ryzen Threadripper 1920X is a 12 core 24 thread CPU, currently second only to the 1950X (16 cores, 32 threads) in AMD’s latest Zen-based line for high end desktop processors. Similarly to the 1950X, it has a base clock speed of 3.5 GHz (3.4 GHz for the 1950X) which can boost to a maximum of 4.0 GHz and features quad channel DDR4 and 64 PCI Express lanes. Also, like the other Threadripper CPUs, the 1920X sits on the latest X399 platform. Intel has a number of processors which outperform the 1920X, such as the i5-7600K which is a quarter of the price and offers around 25% better performance than the 1920X for single and quad core usage (most games only use a maximum of four cores). However, the 1920X is squarely aimed at offering value for money to multi-core workstation users and in this category, the 1920X is closer to competing with Intel’s 15% dearer 10 core, 20 thread i9-7900X. The 8 core, 16 thread 1900X, will shortly be available as the third product in the Threadripper line, featuring a slightly higher base clock of 3.8 GHz. [Aug '17 CPUPro]
