The i7-8700K is Intel’s latest, top of the range, 8th generation Coffee Lake processor. Like Kaby Lake and Sky Lake before that, Coffee Lake is based on Intel’s 14nm architecture which has been slightly optimized on each iteration. Following AMD’s modus operandi, Intel has upped the cores and threads across the range of their CPUs. In previous generations, a 6-core processor would have been a high-end desk-top (HEDT) processor, however the i7-8700K is the first Intel CPU with 6 cores and 12 threads to be classified (and priced) as a mainstream consumer processor. Specifically, the i7-8700K features a base clock speed of 3.7 GHz which boosts to 4.7 GHz (4.5 GHz for the previous generation i7-7700k), 12MB of smart (L3) cache and 2 channels of DDR4 RAM. The majority of the performance improvements over the 7th generation stem from the higher core count which results in a 50% increase in multi-core speed between the i7-7700k and i7-8700k. A new motherboard will need to be factored into the budget when upgrading to the 8700K as it requires a new Intel Z370 chipset which has supposedly been designed to better deliver power to CPUs with a greater number of cores. Also available in this latest release of CPUs is the 6 core 6 thread i5-8600k which is a more rational option (around $100 cheaper) for the vast majority of users that don’t require hyper-threading. Sandy bridge owners can finally justify an upgrade but with the next iteration of AMD's Zen architecture just around the corner the CPU market will be a lot faster moving now that Intel, once again, has to compete. [Sep '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]
