'''Core i7-9800X''' is a {{arch|64}} [[octa-core]] high-performance [[x86]] desktop microprocessor introduced by [[Intel]] in late [[2018]]. This chip, which is based on the {{intel|Skylake|l=arch}} microarchitecture, is fabricated on Intel's [[14 nm process]]. The i7-9800X operates at 3.8 GHz with a TDP of 165 W and a {{intel|Turbo Boost}} frequency of up to 4.4 GHz. The processor supports up to 128 GiB of quad-channel DDR4-2666 memory.

In addition to its {{intel|Turbo Boost}} frequency, the i7-9800X has a {{intel|Turbo Max}} frequency of {{set tbmt|4.5 GHz}}.
