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]

Kaby Lake-X CPUs is probably one of the Intel's most embarrassing release ever for their HEDT platform. Requires X299 motherboard and only offered 16 PCIe lanes whilst being only little better than i7-7700K. [Oct '19 ColdSpy]
