What the Xeon E5-2679 v4 is
The Xeon E5-2679 v4 brings Broadwell-EP to LGA 2011-v3 for power dense racks with DDR4. It launched in October 2016 with a 2.5 GHz base and up to 3.3 GHz boost at 200 W. Intel targets nodes that need 20 cores with high clocks and strong cooling.
Fifty megabytes of Smart Cache carry guests and tables. The high base clock suits demanding tenants. Forty threads cover VMs plus agents.
There is no integrated GPU, so serial and network manage the node. The process is 14 nm. The multiplier is locked. DDR4-2400 with ECC in four channels feeds cores with up to 1.5 TB.
Buyers choose the board at order time with memory and drive tier. The 200 W rating needs robust 2U airflow with redundant fans. Two QPI links at 9.6 GT/s join paired sockets where nodes run 2S.
Socket and motherboard compatibility
The Xeon E5-2679 v4 fits LGA 2011-v3 on C612 server boards with DDR4 slots. Makers list Broadwell-EP with late 2016 BIOS builds. Early stock may need an update.
Dual socket builds are supported with two QPI links. thermal planning matters most with 200 W per socket. The Socket vs chipset: what decides whether a CPU works guide covers matching.
Rack nodes with one or two sockets are the deployment. Growth means more LGA 2011-v3 nodes. Power needs metered racks with high capacity feeds.
Memory, PCIe and cooling
DDR4-2400 with ECC in four channels suits power dense hosts. Quad channel bandwidth helps databases. Start with 256 GB for heavy hosts.
PCIe 3.0 with 40 lanes per CPU serves HBAs and NICs. Boards split lanes between risers and NVMe. Chipset lanes add SATA and USB.
Cooling follows server practice with vendor heatsinks for 200 W classes. No cooler ships in the box. Keep aisles clear and mind the 53 C case limit. ECC guards memory.
Upgrade paths
On the same socket, the Intel Xeon E5-2673 v4 gives 20 cores at 2.3 GHz base for similar racks at 135 W. The Intel Xeon E5-2698 v4 matches 20 cores at 2.2 GHz base at 135 W. Both share LGA 2011-v3 boards.
Twenty two core E5-2699 v4 suits wider hosts where listed. It needs the same boards.
Past power dense hosts move to Skylake-SP gold. The E5-2679 v4 covers late 2016 racks where 20 fast cores with ECC must deploy.
