The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [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]
