Intel socket for Xeon E5 v3 and v4 series processors (Haswell-EP, Broadwell-EP) and Core i7 Extreme. Chipsets: X99 on consumer motherboards and C612 on server motherboards. Quad-channel DDR4 memory. Physically similar to LGA 2011, but not electrically compatible — v1/v2 processors will not work here. 12 to 22-core Xeons are a convenient way to build a workstation.
