Haswell is the codename for a processor microarchitecture developed by Intel as the "fourth-generation core" successor to the Ivy Bridge (which is a die shrink/tick of the Sandy Bridge microarchitecture).[1] Intel officially announced CPUs based on this microarchitecture on June 4, 2013, at Computex Taipei 2013,[2] while a working Haswell chip was demonstrated at the 2011 Intel Developer Forum.[3] Haswell was the last generation of Intel processor to have socketed processors on mobile. With Haswell, which uses a 22 nm process,[4] Intel also introduced low-power processors designed for convertible or "hybrid" ultrabooks, designated by the "U" suffix. Haswell began shipping to manufacturers and OEMs in mid-2013, with its desktop chips officially launched in September 2013.

Haswell CPUs are used in conjunction with the Intel 8 Series chipsets, 9 Series chipsets, and C220 series chipsets.

At least one Haswell-based processor was still being sold in 2022 — the Pentium G3420.[5][6] Windows 7 through Windows 10 were released for the Haswell microarchitecture.
