The Intel i9-9900K is an 8 core, 16 thread, unlocked 9th generation Coffee Lake processor. It has a base / boost clocks of 3.6 / 4.7 GHz and a single-core boost of 5.0 GHz (the highest frequency achieved yet from this class of Intel CPU). It features 16 MB of cache, a 95W TDP and Intel UHD 630 graphics. The 9900K is compatible with the new Z390 chipset, and subject to a BIOS update, is also compatible with the older Z370 chipset. Aimed at users who do not wish to compromise, the i9-9900K offers the best gaming and desktop experience available at any price. Heavy workstation users should consider the Ryzen 9 3900X which is similarly priced. Comparing the overclocked 3900X shows that it is just 10% worse for gaming and desktop (sub octa-core) but around 40% better for 64-core computations. Gamers should consider the 9700K which offers identical overclocked gaming performance at a $100 USD discount. [Oct '18 CPUPro]

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]
