What the Xeon E5-2670 is
Intel Xeon E5-2670 is an eight core Sandy Bridge-EP server processor that Intel released in March 2012 for performance dual socket servers. It runs at 2.6 GHz base with turbo to 3.3 GHz, with 20 MB cache and Hyper-Threading for 16 threads. Power is rated at 115 W on a 32 nm process. High base plus large cache made it the balanced choice for virtualization and database clusters.
No integrated graphics are present. Memory spans DDR3-800 to 1600 over four channels with ECC, and the chip gives 40 PCIe 3.0 lanes plus two 8.0 GT/s QPI links. Thirty-two threads per pair of sockets pack dense mixed workloads.
Boards pair it with registered DIMMs in 2U chassis. All core work near 2.6 GHz keeps throughput high under load. The How to find your CPU socket type guide shows how to confirm the socket before ordering.
Socket and motherboard compatibility
The Xeon E5-2670 fits LGA 2011 in FCLGA2011 form. Dual socket Romley boards with the C600 series controller carry it, with C602 the reference. The vendor list must show the exact E5-2670 string.
At 115 W full size server heatsinks apply. The Socket vs chipset: what decides whether a CPU works guide covers server rules.
Memory, PCIe and cooling
Memory support is DDR3 at 800, 1066, 1333 or 1600 MT/s, four channels, with ECC and registered DIMMs. Two DIMMs per channel at 1600 MT/s give the best bandwidth for sixteen threads.
PCI Express is 40 lanes of PCIe 3.0 per socket. The 8.0 GT/s QPI links join socket pairs. NUMA aware placement guides VM assignment.
Cooling is vendor qualified for 115 W with directed airflow. No retail mount exists.
Upgrade paths
Within LGA 2011 the Xeon E5-2670 can step to faster Sandy Bridge-EP or Ivy Bridge-EP eight core parts on the same board, where power and cooling allow. Memory and storage carry over. A v2 comparison is Intel Xeon E5-2670 v2 on the same socket.
A platform move means a DDR4 generation. Keep the node for heavy threaded duty.
Frequently asked questions
What socket does the Intel Xeon E5-2670 use?
