'''Core i7-7740X''' is a {{arch|64}} [[quad-core]] high-end performance [[x86]] desktop microprocessor introduced by [[Intel]] in [[2017]]. This processor, which is based on the {{intel|Kaby Lake|l=arch}} microarchitecture, is manufactured on Intel's improved [[14 nm process|14nm+ process]]. The i7-7740X operates at 4.3 GHz with a TDP of 112 W and a {{intel|Turbo Boost}} frequency of 4.5 GHz for all cores. This MPU supports up to 64 GiB of dual-channel DDR4-2666 memory.
