The 8 core, 16 thread 1900X is the third and entry-level processor from AMD’s Threadripper series of high-end desktop (HEDT) processors. The 1900X is based on AMD’s 14nm Zen architecture and features 20MB of cache (16MB of which is L3) and quad channel DDR4, which is twice as many channels as in the Ryzen 7 series. It has a base clock of 3.8GHz increasing to a boost of 4.0 GHz and has an additional short-term boost of 0.2 GHz when thermals allow. Most impressively, the 1900X features 64 PCIe lanes which is the same of number of lanes in the nearly twice as expensive Ryzen Threadripper flagship, the 1950X. This facilitates the simultaneous high speed PCIe connection of up to seven different graphics or storage peripherals. By comparison, Intel’s similarly priced 8 core, 16 thread i7-7820X which, even though it has an 11% effective speed advantage over the 1900X, only has 28 PCIe lanes (down from 44 lanes as recently seen in the recent i9-7900X). Both upgrade options may require new, and not inexpensive motherboards, the 7820X requires an X299 (Basin Falls) chipset and the 1900X utilizes the premium X399 motherboard. Despite the considerable price tags attached to the CPUs and motherboards, never before has HEDT processing been so affordable. [Oct '17CPUPro]
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.
