Ivy Bridge is the codename for a line of processors based on the 22 nm manufacturing process developed by Intel. The name is also applied more broadly to the 22 nm die shrink of the Sandy Bridge microarchitecture based on FinFET ("3D") tri-gate transistors, which is also used in the Xeon and Core i7 ''Ivy Bridge-EX'' (Ivytown), ''Ivy Bridge-EP'' and ''Ivy Bridge-E'' microprocessors released in 2013. Ivy Bridge processors are backwards compatible with the Sandy Bridge platform, but such systems might require a firmware update (vendor specific). In 2011, Intel released the 7-series Panther Point chipsets with integrated USB 3.0 to complement Ivy Bridge. Volume production of Ivy Bridge chips began in the third quarter of 2011. Quad-core and dual-core-mobile models launched on 29 April 2012 and 31 May 2012 respectively. Core i3 desktop processors, as well as the first 22 nm Pentium, were announced and available the first week of September, 2012. == Overview == The Ivy Bridge CPU microarchitecture is a shrink from Sandy Bridge and remains largely unchanged. Like its predecessor, Sandy Bridge, Ivy Bridge was also primarily developed by Intel's Israel branch, located in Haifa, Israel. Notable improvements include: * 22 nm Tri-gate transistor ("3-D") technology (up to 50% less power consumption at the same performance level as 2-D planar transistors).〔(【引用サイトリンク】 Intel Reinvents Transistors Using New 3-D structure )〕 * A new random number generator and the RdRand instruction, codenamed Bull Mountain. 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「Ivy Bridge (microarchitecture)」の詳細全文を読む スポンサード リンク
