Intel Sandy Bridge-based Xeon microprocessors (often referred to as Sandy Bridge-E[1]) are microprocessors based on the Intel's 32 nm Sandy Bridge architecture for servers, workstations, and high-end desktops.
There are five different families of Xeon processors that were based on Sandy Bridge architecture: IGPU is absent on most of these processors unless noted otherwise.
All models support: MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, Enhanced Intel SpeedStep Technology (EIST), Intel 64, XD bit (an NX bit implementation), TXT, Intel VT-x, Intel EPT, Intel VT-d, Intel VT-c,[2] Intel x8 SDDC,[3] Hyper-threading (except E5-1603, E5-1607, E5-2603, E5-2609 and E5-4617), Turbo Boost (except E5-1603, E5-1607, E5-2603, E5-2609, E5-4603 and E5-4607), AES-NI, Smart Cache.
