Skylake is Intel's codename for its sixth generation Core microprocessor family that was launched on August 5, 2015, succeeding the Broadwell microarchitecture. Skylake is a microarchitecture redesign using the same 14 nm manufacturing process technology as its predecessor, serving as a tock in Intel's tick–tock manufacturing and design model. According to Intel, the redesign brings greater CPU and GPU performance and reduced power consumption. Skylake CPUs share their microarchitecture with Kaby Lake, Coffee Lake, Whiskey Lake, and Comet Lake CPUs.

Skylake is the last Intel platform on which Windows versions earlier than Windows 10 are officially supported by Microsoft, although enthusiast-created modifications are available that disabled the Windows Update check and allowed Windows 8.1 and earlier to continue to receive Windows Updates on this and later platforms.

Some of the processors based on the Skylake microarchitecture are marketed as sixth-generation Core.

Intel officially declared end of life and discontinued Skylake LGA 1151 CPUs (except i3-6100, i5-6500, and Xeon E3 v5) on March 4, 2019.
