Intel’s Comet Lake flagship, the i9-10900K, is the fastest gaming and desktop CPU currently available. This ten-core hyperthreaded processor can easily be overclocked so that all twenty threads run at an eye-watering 5.2 GHz. Whilst its stellar performance is second to none, it comes with a premium price tag of $488 USD. The 10900K also requires a new (Z490) LGA1200 motherboard, which Intel has indicated will remain compatible with Rocket Lake CPUs which are due later this year. Whilst AMD’s competing $420 USD Ryzen 3900X and $675 USD Ryzen 3950X do have a greater number of cores, their lower clock speeds and higher memory latency handicap them in non-rendering use cases. Overall, the 10900K has a 16% effective speed advantage over both the 3900X and 3950X. Users that do a lot of rendering should investigate dedicated hardware encoders such as NVENC and Quick Sync as these are far more efficient than CPU based rendering. Comparing the 10900K and 10700K shows that, when paired with a 2060S, the 10700K offers comparable gaming performance for 20% less money.[Jun '20CPUPro]
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?
