What the Xeon E7-4870 is
Intel Xeon E7-4870 is a ten core Westmere-EX server processor that Intel released in April 2011 for four socket boards. It runs at 2.4 GHz base with turbo to 2.8 GHz and includes Hyper-Threading, so 10 cores give 20 threads. Cache is 30 MB Intel Smart Cache. Power is 130 W on a 32 nm process.
Four socket boards hold 80 threads with this chip for large virtual farms. The 30 MB shared cache cuts latency for database work. Up to 512 GB of memory fits per socket on qualified boards.
There is no integrated graphics on this die. Each socket carries four DDR3 channels with ECC. The chip launched on April 3, 2011.
Socket and motherboard compatibility
The Xeon E7-4870 fits LGA 1567 in FCLGA1567 form. Four socket server boards with the Intel 7500 chipset carry it. The board BIOS must list the exact E7-4870 string.
CPUs connect over QuickPath Interconnect at 6.4 GT/s, while PCIe comes from the chipset. A board that lists E7-4800 strings is the safe choice for four socket builds.
Memory, PCIe and cooling
Memory support is DDR3, ECC registered with buffering, four channels per socket, up to 512 GB per socket on qualified boards. Fill risers in matched sets per the board manual.
QPI links run at 6.4 GT/s between sockets. PCIe comes from the Intel 7500 chipset rather than the processor.
Cooling uses board specific server heatsinks with M3 screws under data center airflow. Match the heatsink to the chassis direction.
Upgrade paths
On LGA 1567 the E7-4870 already tops the four socket range on cache, so later steps are E7 v2 parts on new boards. Memory and storage carry over only with a new platform. A same family reference is Intel Xeon E7-2850.
A platform move to a current server socket needs new boards and DDR4 memory. Keep the E7 board for database duty.
Frequently asked questions
