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 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 '17 CPUPro]
