Processor E7-2800/4800/8800 v2 Product Family processors are the
next generation of 64-bit, multi-core enterprise processors built on 22-nanometer
process technology. The Intel Xeon processor E7 v2 product family implements multiple
multi-threaded (two threads) cores based upon the Intel Xeon processor E7 v2 product
family core design. A large, up to 37.5 MB, last-level cache (LLC) has been
implemented to be shared across all active cores.The Intel Xeon processor E7 v2
product family supports two on-chip memory controllers. It is designed primarily for
glueless four- or eight-socket multiprocessor systems, and features three Intel®
QuickPath Interconnects (Intel® QPI) and four Intel® Scalable Memory Interconnect
(Intel® SMI) channels.

The Intel® Xeon® E7 v2 product family-based platform supports four fully-connected
Intel Xeon processor E7 v2 product family sockets, where each Intel Xeon processor E7
v2 product family uses three Intel QuickPath Interconnects to connect to the other
sockets and can connect to the PCH via the x4 DMI Gen 2 channel. The Intel Xeon
processor E7 v2 product family maintains cache coherence at the platform level by
supporting the Intel QuickPath Interconnect source broadcast snoopy protocol.

The Intel Xeon processor E7 v2 product family is designed to support Intel QuickPath
Interconnects at speeds of 8, 7.2 and 6.4 GT/s and DDR3 - 1067, 1333 and 1600 MT/s
memory speeds. It uses a power-through-the-pins power delivery system and new
socket R1.
