Haswell is the codename for a processor microarchitecture developed by Intel as the successor to the Ivy Bridge microarchitecture. 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. With Haswell, which uses a 22 nm process, Intel also introduced low-power processors designed for convertible or "hybrid" ultrabooks, designated by the "Y" suffix. For the Intel Core processors based on Haswell, they are marketed as the 4th generation of Core i3, i5, and i7.〔http://ark.intel.com/products/family/75023/4th-Generation-Intel-Core-i7-Processors〕 Haswell CPUs are used in conjunction with the Intel 8 Series chipsets and Intel 9 Series chipsets. ==Design== 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. Haswell has been launched in three major forms: * Desktop version (LGA 1150 socket and the new LGA 2011-v3 socket): ''Haswell-DT'' * Mobile/Laptop version (PGA socket): ''Haswell-MB'' * BGA version: * * 47 W and 57 W TDP classes: ''Haswell-H'' (For "All-in-one" systems, Mini-ITX form factor motherboards, and other small footprint formats.) * * 13.5 W and 15 W TDP classes (MCP): ''Haswell-ULT'' (For Intel's UltraBook platform.) * * 10 W TDP class (SoC): ''Haswell-ULX'' (For tablets and certain UltraBook-class implementations.) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Haswell (microarchitecture)」の詳細全文を読む スポンサード リンク
