The FX-8370 is a top of the range black edition Vishera eight core processor based on AMD’s Piledriver architecture. It was launched in September 2014 and is both cheaper and faster than the FX-8350. The FX range offers high performance and this particular processor holds a world record for reaching an incredible 8.7 GHz when overclocked under lab conditions. For typical users however, the FX-8370 runs at 4.0/4.3 GHz (base/turbo) and typically hits 5.0 GHz when overclocked. Its effective speed is 83 which is currently only exceeded by AMD's 20% more expensive FX-9590 (scoring 85), making it relatively good value for money. Eight cores aren’t necessary for most applications, but things are changing and if you heavily rely on multi-threaded applications then the FX-8370 may be a good choice. [Dec '14 CPUPro]

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]
