Desktop variants of Haswell draw between 8% and 23% more power under load than Ivy Bridge.Up to 5% higher single-threaded performance.Approximately 8% faster vector processing.All other versions come as dual- or quad-core variants. Due to the low power requirements of tablet and UltraBook platforms, Haswell-ULT and Haswell-ULX are only available in dual-core configurations.See also Intel HD and Iris Graphics for more details. All other models have GT3 ( Intel HD 5000 or Intel Iris 5100), GT2 (Intel HD 4200, 4400, 4600, P4600 or P4700) or GT1 (Intel HD Graphics) integrated graphics. Only certain quad-core variants and BGA R-series stock keeping units (SKUs) receive GT3e ( Intel Iris Pro 5200) integrated graphics. ULT = Ultra Low TDP ULX = Ultra Low eXtreme TDP.10 W TDP class (SoC): Haswell-ULX (for tablets and certain UltraBook-class implementations).13.5 W and 15 W TDP classes ( MCP): Haswell-ULT (for Intel's UltraBook platform).47 W and 57 W TDP classes: Haswell-H (for "All-in-one" systems, Mini-ITX form factor motherboards, and other small footprint formats).Mobile/Laptop version ( PGA socket): Haswell-MB.Desktop version ( LGA 1150 socket and the LGA 2011-v3 socket): Haswell-DT.Haswell has been launched in three major forms: The Haswell architecture is specifically designed to optimize the power savings and performance benefits from the move to FinFET (non-planar, "3D") transistors on the improved 22 nm process node. Windows 7 through Windows 10 were released for the Haswell microarchitecture. Haswell CPUs are used in conjunction with the Intel 8 Series chipsets, Intel 9 Series chipsets, and Intel C220 series chipsets.Īt least one Haswell-based processor was still being sold in 2022 - the Pentium G3420. With Haswell, which uses a 22 nm process, Intel also introduced low-power processors designed for convertible or "hybrid" ultrabooks, designated by the "U" suffix. Intel officially announced CPUs based on this microarchitecture on June 4, 2013, at Computex Taipei 2013, while a working Haswell chip was demonstrated at the 2011 Intel Developer Forum. 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).
