Ivy Bridge (IVB) was Intel's microarchitecture based on the 22 nm process for desktops and servers. Ivy Bridge was introduced in 2011 as a process shrink of Sandy Bridge which introduced a number of enhancements. Ivy Bridge became Intel's first microarchitecture to use tri-gate transistors for their commercial products.

For desktop and mobile, Ivy Bridge is branded as 3rd Generation Intel Core processors. For server class processors, Intel branded it as Xeon E3 v2, Xeon E5 v2, and Xeon E7 v2.

Ivy Bridge is designed to be manufactured using 22 nm Tri-gate FinFET transistors. This is Intel's first generation of FinFET. This correlates to 8 nm Fin width and a 60 nm Fin pitch (shown below). SRAM cell is at 0.1080 µm² and 0.092 µm² for high performance and high density respectively.
