Succession
Westmere Ivy Bridge

Sandy Bridge (SNB) was the microarchitecture for Intel's 32 nm process for desktops and servers. Sand Bridge was introduced in 2010 to replace Nehalem and become the successor to Westmere.

For desktop and mobile, Sandy Bridge is branded as 2nd Generation Intel Core processors. For server class processors, Intel branded it as 1st generation (V1) Xeon E3, Xeon E5, and Xeon E7.
