Skylake is the codename used by Intel for a processor microarchitecture which was launched in August 2015 succeeding the Broadwell microarchitecture. Skylake is a microarchitecture redesign using the same 14 nm manufacturing process technology as its predecessor Broadwell, serving as a "tock" in Intel's "" manufacturing and design model. According to Intel, the redesign brings greater CPU and GPU performance and reduced power consumption. It has been succeeded by Kaby Lake.
Skylake is the last Intel platform fully supported for versions of Windows earlier than Windows 10.
Skylake's development, as with processors such as Banias, Dothan, Conroe, Sandy Bridge and Ivy Bridge, was primarily undertaken by Intel Israel at its engineering research center in Haifa, Israel. The Haifa development team worked on the project for four years, and faced many challenges: "But by re-writing the microarchitecture and developing new concepts such as the Speed Shift Technology, we created a processor for 4.5 W to 45 W mobile devices, and up to 91 W for desktop devices." The Skylake processors will be used to power a wide range of devices, from smartphones and tablets, all the way to desktops. "Because of Skylake's features, companies will be able to release laptop PCs that are half as thick and half as heavy as those from five years ago," according to Intel.
In September 2014, Intel announced the Skylake microarchitecture at the Intel Developer Forum in San Francisco, and that volume shipments of Skylake CPUs were scheduled for the second half of 2015. Also, the Skylake development platform was announced to be available in Q1 2015. During the announcement, Intel also demonstrated two computers with desktop and mobile Skylake prototypes: the first was a desktop testbed system, running the latest version of 3DMark, while the second computer was a fully functional laptop, playing 4K video.
