Ivy Bridge (microarchitecture)
Ivy Bridge is the codename for Intel's 22 nm microarchitecture used in the third generation of the Intel Core processors (Core i7, i5, i3). Ivy Bridge is a die shrink to 22 nm process based on FinFET ("3D") Tri-Gate transistors, from the former generation's 32 nm Sandy Bridge microarchitecture—also known as tick–tock model. The name is also applied more broadly to the Xeon and Core i7 Extreme Ivy Bridge-E series of processors released in 2013.

Ivy Bridge processors are backward 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 and SATA 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 April 29, 2012 and May 31, 2012 respectively. Core i3 desktop processors, as well as the first 22 nm Pentium, were announced and available the first week of September 2012.
Ivy Bridge is the final Intel platform on which versions of Windows prior to Windows 7 will be officially supported by Microsoft. It is also the earliest Intel microarchitecture to officially support Windows 10 64-bit (NT 10.0).
