This was the ultimate niche CPU. At the time of its release, it had an optimal combination of multi-core performance without sacrificing as much single- and quad- as the higher-core CPUs, at an excellent price-point. It utilizes quad-channel RAM. If you were a content creator without external funding, had one machine in the budget, then this chip might even now in mid-2019 be what you're looking for. The higher-end Threadrippers will throw more cores at you... for up to five times the price. If you've a home studio, running a DAW on the same PC you use for everything; or you do your own video editing; or you're an independent streamer; then those extra 12 or 18 cores aren't really going to help you that much anyway, for all that extra cash - AND those CPUs have lower performance in more common applications (single- low-thread apps). Not worth it. Intel isn't even on the table, of course. If you're reading this in the future: these benchmarks have multiple categories for a reason. Read and think. Find the best combination for what you intend to do with it - not some arbitrary "the best" overall. There is no such thing, because you won't be using your computer for Overall, now will you? [Aug '19 spacefiddle]

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]
