'''Core i7-7820X''' is a {{arch|64}} [[octa-core]] high-performance [[x86]] desktop microprocessor introduced by [[Intel]] in mid-[[2017]].  This chip, which is based on the {{intel|Skylake|l=arch}} microarchitecture, is fabricated on Intel's enhanced [[14 nm process|14nm+ process]]. The i7-7820X operates at 3.6 GHz with a TDP of 140 W and a {{intel|Turbo Boost}} frequency of 4.3 GHz. The processor supports up to 128 GiB of quad-channel DDR4-2666 memory.
 
  
−
In addition to its {{intel|Turbo Boost}} frequency, the i7-7820X has a {{intel|Turbo Max}} frequency of {{set tbmt|4.5 GHz}}.
