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]

MORE DETAILS

Core i7-9800X is a 64-bit octa-core high-performance x86 desktop microprocessor from Intel (late 2018). A Skylake micro-architecture chip, is fabricated on using Intel's 14 nm process. The i7-9800X operates at 3.8 GHz with a TDP of 165 W and a Turbo Boost frequency of up to 4.4 GHz and am Turbo Max Boost frequency of 4.5 GHz. The processor supports up to 128 GiB of quad-channel DDR4-2666 memory and supports 44 PCIe lanes. A strong contender to the i9-9900k, yet slightly slower, except utilizing the x299 platform allowing for more ram and PCIe lanes (44 vs 16) [Jan '19 deweycd]
