Haswell (microarchitecture)
open-in-new
<p>Haswell is the <a href="/facts/List_of_Intel_codenames/bHsKcU7u">codename</a> for a <a href="/facts/Central_processing_unit/Jxp1bqMV">processor</a> <a href="/facts/Microarchitecture/NFRd4NUL">microarchitecture</a> developed by <a href="/facts/Intel/SMF0gJJX">Intel</a> as the "fourth-generation core" successor to the <a href="/facts/Ivy_Bridge_(microarchitecture)/VklHpEK1">Ivy Bridge</a> (which is a <a href="/facts/Die_shrink/fgJ8nL4b">die shrink</a>/<a href="/facts/Tick%25E2%2580%2593tock_model/CeKPeLur">tick</a> of the <a href="/facts/Sandy_Bridge/os1WwI9l">Sandy Bridge microarchitecture</a>). Intel officially announced <a href="/facts/CPU/Jxp1bqMV">CPUs</a> based on this microarchitecture on June 4, 2013, at <a href="/facts/Computex_Taipei/lmhhc4df">Computex Taipei</a> 2013, while a working Haswell chip was demonstrated at the 2011 <a href="/facts/Intel_Developer_Forum/vIoThJxk">Intel Developer Forum</a>. Haswell was the last generation of Intel processor to have socketed processors on mobile. With Haswell, which uses a <a href="/facts/22_nm_process/zr0VI9w6">22 nm process</a>, Intel also introduced low-power processors designed for convertible or "hybrid" <a href="/facts/Ultrabooks/zYdlujhX">ultrabooks</a>, designated by the "U" suffix. Haswell began shipping to manufacturers and <a href="/facts/Original_equipment_manufacturer/hmUhIWaS">OEMs</a> in mid-2013, with its desktop chips officially launched in September 2013. </p><p>Haswell CPUs are used in conjunction with the <a href="/facts/Intel_8_Series_chipsets/1YD0bNRr">Intel 8 Series chipsets</a>, <a href="/facts/Intel_9_Series_chipsets/1YD0bNRr">9 Series chipsets</a>, and <a href="/facts/Intel_Xeon_chipsets/FDJleJF6">C220 series chipsets</a>. </p><p>At least one Haswell-based processor was still being sold in 2022 — the Pentium G3420. <a href="/facts/Windows_7/tldLdbnX">Windows 7</a> through <a href="/facts/Windows_10/be9IHehJ">Windows 10</a> were released for the Haswell microarchitecture. </p>
