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]

The I7-7820X is the second of three new Skylake-X HEDT (high end desktop processors) released by Intel as part of their core X series (the others being the flagship 10-core i9-7900X and the 6-core i7-7800X). The 7820X is an 8-core, 16-thread CPU which will amply satisfy all but the heaviest of multi-threaded use cases. The 7820X requires a relatively expensive X299 (Basin Falls) motherboard, which costs upwards of $250. The 7820X is listed at $599 which is about $200 more than AMD's current flagship 8-core, 16 thread Ryzen 7 1800X. In addition to better IPC, the 7820X is higher clocked with base and max boost clocks of 3.6/4.5 GHz respectively, compared to 3.6G/4.0 GHz for the Ryzen 7 1800X. The additional $200 (50%) buys you around 20% more performance in both single and multi core workloads. Intel have also released several Kabylake-X HEDT CPUs: the 4-thread i5-7640X and the 8-thread i7-7740X and will shortly release of even higher spec Skylake-X processors. It's probably wise to hold off purchasing until the eagerly anticipated 16-core, 32-thread Ryzen Threadripper CPUs are launched later this month. [Jul '17 CPUPro]
