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]

AMD released the FX-9590 back in July 2013 but it's not until recently that these processors have started hitting the shelves and even now prices are still extremely high. This is the first mainstream 5GHz processor but clock speed isn't the key performance indicator it once was. Comparing the 9590 to the 8350 shows that the 9590 has 16% better overall performance which is almost exactly in line with its base clock increase from 4.0 to 4.7 GHz. Despite this performance boost the 9590 still lags Intel's most recent 4770K Haswell processor by 26% and that's despite the AMD's 27% higher base clock. In terms of relative performance the AMD's strong point is Integer processing where it has 8 processing units vs just four (one per core) in the 4770K. Overall, especially at current prices, the 9590 doesn't represent good value for money. [Jan '14 CPUPro]
