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 '18CPUPro]
These APUs are still good candidates for budget eSport gaming and most AAA titles with the sole exception of CP2077.
However, they come with a catch, as you will need to use very high clock speed RAM (DDR3 2133 or 2400 on XMP) to get decent results with the onboard graphics (Which can trade blows with a GT 730 easily), if you want decent single core performance, you will need to overclock them over 4.0GHz base, preferably at 4.5GHz, however, getting past 4.5GHz base will yield you only two overclocked cores and two at idle clockspeed (1.7GHz).
If high speed DDR3 is cheap on your location, get one of these APUs, they are certainly worth it if they are cheap. [Feb '21derwolf019]
