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]
