What the Xeon E7-8870 v3 is
The Xeon E7-8870 v3 is a balanced 18 core Haswell-EX part on LGA 2011-1 for dense 8S virtualization. Intel set 18 cores and 36 threads at 2.1 GHz base with turbo to 2.9 GHz. Forty five megabytes of last level cache feed many guests. Power is 140 W on 22 nm from the second quarter of 2015.
Eighteen cores maximize threads per socket for consolidation across eight sockets. Lower base clocks trade latency for density versus frequency tuned parts. Three QPI links at 9.6 GT/s mesh the system. The 140 W envelope fits 8S racks better than 165 W flagships.
DDR4 and DDR3 ECC over four channels to 1.5 TB per socket scale to 12 TB per system. Buyers pick the 8870 v3 where 144 cores per 8S system must fit power and license plans.
Socket and motherboard compatibility
The 8870 v3 fits LGA 2011-1 on Brickland 8S boards with dense firmware builds. E7-8800 validates to eight sockets. Check vendor stepping lists before expanding half populated systems.
ECC memory is DDR3 or DDR4 per system. The Socket vs chipset: what decides whether a CPU works guide covers ideas, vendor 8S manuals decide DIMM and QPI topologies.
Memory, PCIe and cooling
Memory to 1.5 TB per socket with ECC suits 8S consolidation. DDR4 preferred for bandwidth per thread. Even populations across eight sockets protect NUMA fairness.
PCIe 3.0 with 32 lanes per socket serves fabrics and storage. Dense VMs need network throughput. Placement should respect socket locality.
Cooling uses 140 W 8S heatsinks with managed airflow. Eighteen cores run hot under all core loads. Inlet control protects base clocks.
Upgrade paths
On the same socket the Intel Xeon E7-8860 v3 at 16 cores below saves cost, while the Intel Xeon E7-8890 v3 at 18 faster cores lifts clocks above. All share LGA 2011-1 where listed.
A v4 move needs Broadwell-EX firmware. The 8870 v3 holds balanced 18 core 8S where density per watt matters.
