What the Xeon E5-4620 v3 is
The Xeon E5-4620 v3 is a value 10 core Haswell-EP part on LGA 2011-v3 for scale out 4S servers. Intel set 10 cores and 20 threads at 2.0 GHz base with turbo to 2.6 GHz. Twenty five megabytes of Smart Cache cover workers. Power is 105 W on 22 nm from the second quarter of 2015.
Lower clocks favor throughput per watt over latency. Twenty threads handle parallel web and mid tier loads. Two QPI links at 8 GT/s tie up to four sockets. The 105 W envelope fits dense racks better than 135 W frequency parts.
No integrated graphics exist. DDR4 with ECC over four channels feeds guests. Buyers pick the 4620 v3 where socket count with modest clocks beats fewer faster cores on node budgets.
Socket and motherboard compatibility
The 4620 v3 fits LGA 2011-v3 on C612 4S Grantley boards. Firmware must list E5-4600 v3 SKUs. The socket also carries HEDT silicon, but server boards need C612 with ECC RDIMMs. Check vendor DIMM maps before populating.
Registered ECC memory is required for capacity. The Socket vs chipset: what decides whether a CPU works guide covers ideas, vendor manuals decide layouts. LGA 2011 without v3 never accepts v3 Xeons.
Memory, PCIe and cooling
DDR4 ECC over four channels to 768 GB per socket suits scale out hosts. Registered DIMMs allow large counts. Speeds follow the 1866 class on value SKUs. Fill all channels for bandwidth.
PCIe 3.0 with 40 lanes per socket serves networking and storage in x4, x8 and x16 splits. Value nodes often need network fabric more than accelerators. NUMA locality guides placement.
Cooling uses 105 W server heatsinks with front to back airflow. No retail cooler exists. Modest clocks ease thermal density in packed rows.
Upgrade paths
On the same socket the Intel Xeon E5-4627 v3 lifts to 2.6 GHz to 3.2 GHz without threads for frequency work, while the Intel Xeon E5-4610 v3 trims to 1.7 GHz fixed for lower power. All share LGA 2011-v3 where listed.
A move to v4 needs Broadwell-EP firmware. The 4620 v3 covers value 10 core Haswell-EP where threads per watt decide.
