when did 4th generation intel processors come out
Haswell (microarchitecture) Haswell is the codename for a processor microarchitecture developed by Intel as the "fourth-generation core" successor to the Ivy 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] With Haswell, which uses a 22 nm process,[4] Intel also introduced low-power processors designed for convertible or "hybrid" ultrabooks, designated by the "Y" suffix.
