Core i7-8665U is a 64-bit quad-core performance x86 mobile microprocessor introduced by Intel in early 2019. This processor, which is based on an enhanced version of the Whiskey Lake microarchitecture, is manufactured on Intel's 3rd generation enhanced 14nm++ process. The i7-8665U operates at 1.9 GHz with a TDP of 15 W and Turbo Boost frequency of up to 4.8 GHz. This MPU supports up to 32 GiB of dual-channel DDR4-2400 memory and incorporates Intel's UHD Graphics 620 IGP operating at 300 MHz with a burst frequency of 1.15 GHz.

This model supports a configurable TDP of 10 W TDP-down and 25 W TDP-up.

Preliminary Data! Information presented in this article deal with a microprocessor or chip that was recently announced or leaked, thus missing information regarding its features and exact specification. Information may be incomplete and can change by final release.

Cache

Main article: Whiskey Lake § Cache

[Edit/Modify Cache Info]

Cache Organization Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory. The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC. Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies. Note: All units are in kibibytes and mebibytes.
