Instruction set: SSE4.1, SSE4.2, AVX2
Virtualization: VT-x, VT-x EPT, VT-d
Intel Xeon E5 v3 processors for the LGA 2011-3 socket can provide up to 22 CPU cores plus hyperthreading and are therefore among the fastest processors from Intel. Mainboards for the LGA 2011 socket can accommodate up to 2 CPUs at the same time, so setups with 44 physical plus 44 "virtual" cores (HT) are possible, which in total allows the simultaneous processing of 88 threads.

The Xeon E5 v3 dominated the picture in pretty much every benchmark and were consistently at the top of Passmark, Cinebench 11.5 and Geekbench 3. The top model Intel Xeon E5-2699 v4 has 22 CPU cores, which operate at 2.2 GHz in the base are clocked. The processor can increase its clock frequency to up to 3.6 GHz (when only one CPU core is loaded) via Turbo mode. Up to 2.8 GHz are possible with simultaneous load on several cores. Since the Intel Xeon E5 family is purely a server product, it cannot be overclocked.

All Intel Xeon E5 processors support the error correction ECC of the main memory. The top model, Intel Xeon E5-2699 v4, can address RAM up to DDR4-2400 in four memory channels (quad-channel). Using quad-channel mode quadruples the server's memory bandwidth and can have a positive effect on computing-intensive applications. The Intel Xeon E5-2699 v4 is specified with a TDP of (only) 145 watts, which is relatively human considering the 22 CPU cores. The processor benefits from the stable Intel 14 nm manufacturing and the newer Broadwell EP architecture.

The Intel Xeon E5 processors were discontinued in 2017. Intel now offers newer server processors in the Intel Xeon Silver (formerly Intel Xeon E3), Intel Xeon Gold (formerly Intel Xeon E5) and Intel Xeon Platinum (formerly Intel Xeon E7) families.
