What the Xeon E5-2695 v3 is
The Xeon E5-2695 v3 is an OEM Haswell-EP fourteen core for vendor clouds on LGA 2011-v3. Intel set fourteen cores and 28 threads at 2.3 GHz base with turbo to 3.3 GHz. Thirty five megabytes of Smart Cache serve dense guests. Power is 120 W on 22 nm from September 2014. Higher clocks than the 2683 v3 suit vendor tenants that need both density and response.
Fourteen cores consolidate virtual machines per socket at strong ratios. Turbo to 3.3 GHz lifts control tasks while base holds all core work. Large cache covers many tenants. ECC DDR4 protects data. No integrated graphics exist. Fabric and NVMe storage shape throughput. Used buyers find this SKU in vendor pulls.
DDR4 ECC over four channels feeds each socket with two QPI links between dual nodes. The mix is a server socket for vendor clouds where fast fourteen cores at 120 W are wanted.
Socket and motherboard compatibility
The E5-2695 v3 fits LGA 2011-v3 on vendor C612 Grantley platforms. OEM validation may block generic boards. Confirm the system matrix before purchase. X99 desktop never accepts this OEM server part.
ECC RDIMMs over four channels carry memory. The Socket vs chipset: what decides whether a CPU works guide is desktop focused, so follow vendor rules. Cooling uses vendor 120 W heatsinks with rack airflow.
Retail high core E5 v3 offer broader support where OEM locks bind. Verify microcode first.
Memory, PCIe and cooling
DDR4 ECC quad channel per socket suits dense virtualization. Even maps protect NUMA balance. Large RDIMMs reach high counts. Speed follows population per manual.
Forty PCIe lanes per socket feed fabric HBAs and NVMe. NUMA placement across QPI links matters at fourteen cores. Vendor manuals detail slots.
Vendor 120 W cooling handles sustained loads with cool inlets. No retail cooler exists. Turbo residency follows per core states.
Upgrade paths
Within the socket the Intel Xeon E5-2683 v3 with fourteen cores is a slightly slower OEM twin on vendor systems. The Intel Xeon E5-2698 v3 with sixteen cores is a higher density retail step. Both need platform checks.
Newer sockets replace Grantley. The E5-2695 v3 covers OEM clouds where fast fourteen cores at 120 W are the pick.
