Intel Xeon E7-8893 v3 socket: LGA 2011-1

What the Xeon E7-8893 v3 is

The Xeon E7-8893 v3 is the top clock Haswell-EX part on LGA 2011-1 for single thread 8S databases. Intel set 4 cores and 8 threads at 3.2 GHz base with turbo to 3.5 GHz. Forty five megabytes of last level cache is vast for four cores. Power is 140 W on 22 nm from the second quarter of 2015.

Four fast cores with huge cache suit single thread ERP steps at 8S scale. High base clocks lead all E7 v3 parts. Three QPI links tie eight sockets for memory scale rather than thread scale. Per core licenses favor few cores with maximum speed.

DDR4 and DDR3 ECC over four channels to 1.5 TB per socket give exceptional bandwidth per core. Buyers pick the 8893 v3 where four fast cores with 45 MB of cache beat any dense part on response time.

Socket and motherboard compatibility

The 8893 v3 fits LGA 2011-1 on Brickland 8S boards with 140 W support. E7-8800 validates to eight sockets. Firmware must list the 4 core stepping. Verify power and cooling for 140 W at high clocks.

ECC memory is DDR3 or DDR4 per system. The Socket vs chipset: what decides whether a CPU works guide covers concepts, vendor docs decide DIMM use for few core configs.

Memory, PCIe and cooling

Memory to 1.5 TB per socket with ECC suits 8S memory scale with few compute cores. Four cores share four channels for top per thread bandwidth. DDR4 preferred.

PCIe 3.0 with 32 lanes per socket serves fabrics for distributed queries. Single thread systems need network speed for scale out steps. NUMA tuning still matters at 8S.

Cooling uses 140 W 8S heatsinks with strong airflow. Four hot cores need cool inlets to hold 3.2 GHz. No retail cooler exists.

Upgrade paths

On the same socket the Intel Xeon E7-8891 v3 with 10 cores at 2.8 GHz to 3.5 GHz nearby adds threads for similar clocks, while the Intel Xeon E7-8890 v3 with 18 cores covers density. All share LGA 2011-1 where listed.

A v4 move needs new firmware. The 8893 v3 remains the per core clock lead in Haswell-EX 8S.
