# Intel Sandy Bridge-based Xeon microprocessors

Intel Sandy Bridge-based Xeon microprocessors (often referred to as Sandy Bridge-E) are microprocessors based on the Intel's 32 nm Sandy Bridge architecture for servers, workstations, and high-end desktops. It succeeds the six-core Gulftown/Westmere-EP processor which used the older LGA 1366 package, and uses LGA 2011, LGA 1356 and LGA 1155 socket depending on the package.

## Overview

There are five different families of Xeon processors that were based on Sandy Bridge architecture:
* Sandy Bridge-E (LGA 2011) targeted high-end desktop (HEDT) enthusiast segment. It was branded as Core i7 Extreme Edition and Core i7 processors, despite sharing many similarities with Xeon models.
* Sandy Bridge-EP (LGA 2011) branded as Xeon E5 models aimed at high-end servers and workstations. It supported motherboards equipped with up to 4 sockets.
* Sandy Bridge-EN (LGA 1356) uses a smaller socket for low-end and dual-processor servers on certain Xeon E5 and Pentium branded models.
* Sandy Bridge Xeon (LGA 1155) were mostly identical to its desktop counterparts apart from the missing IGPU despite branded as Xeon E3 processors.
* Gladden (BGA 1284) Xeon E3 models were for embedded applications.
IGPU is absent on most of these processors unless noted otherwise.
