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.
