What the Xeon E7-8890 v3 is
The Xeon E7-8890 v3 is the flagship 18 core Haswell-EX part on LGA 2011-1 for mission critical 8S systems. Intel set 18 cores and 36 threads at 2.5 GHz base with turbo to 3.3 GHz. Forty five megabytes of last level cache cover the largest guests. Power is 165 W on 22 nm from the second quarter of 2015.
Top base and turbo for 18 cores suit databases with strict latency goals at 8S scale. Three QPI links at 9.6 GT/s mesh eight sockets for 144 cores per system. The 165 W envelope demands flagship 8S cooling and power. Per core performance leads the 18 core line.
DDR4 and DDR3 ECC over four channels to 1.5 TB per socket scale to 12 TB per system with RAS options. Buyers pick the 8890 v3 where 8S scale cannot compromise per core speed.
Socket and motherboard compatibility
The 8890 v3 fits LGA 2011-1 on Brickland 8S flagship boards. E7-8800 validates to eight sockets. Firmware must carry the top bin stepping. Power budgets differ from lower watt 8S boards, so verify VRMs.
ECC memory is DDR3 or DDR4 per system with mirroring and sparing. The Socket vs chipset: what decides whether a CPU works guide covers concepts, vendor flagship docs decide RAS maps.
Memory, PCIe and cooling
Memory to 1.5 TB per socket with ECC and up to 85 GB/s suits flagship 8S databases. DDR4 at 1866 preferred. Full populations with RAS protect mission critical data.
PCIe 3.0 with 32 lanes per socket serves top tier fabrics and storage. Flagship I/O needs NUMA tuned placement. QPI bandwidth carries cross socket queries.
Cooling uses flagship 165 W 8S heatsinks with precision airflow. No retail cooler exists. Top clocks need the coolest inlets in the row.
Upgrade paths
On the same socket the Intel Xeon E7-8880 v3 at 150 W nearby saves power for similar threads, while the Intel Xeon E7-8891 v3 with 10 faster cores serves per core licenses. All share LGA 2011-1 where listed.
A v4 flagship move needs new firmware. The 8890 v3 remains the Haswell-EX 8S performance lead.
