What the Xeon E5-2687W is
Intel Xeon E5-2687W is an eight core Sandy Bridge-EP server processor that Intel released in March 2012 for single socket workstations. It runs at 3.1 GHz base with turbo to 3.8 GHz, with 20 MB cache and Hyper-Threading for 16 threads. Power is rated at 150 W on a 32 nm process. The W suffix marks workstation tuning with the highest Sandy EP clocks for interactive creation work.
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 for workstation GPUs and storage controllers. Very high clocks with eight cores suit rendering and simulation that mix single threaded modeling with threaded batch work.
Workstation towers pair it with 32 GB to 64 GB of ECC DDR3 and a professional GPU. All core work near 3.1 GHz keeps batch throughput high while modeling stays direct. The How to find your CPU socket type guide shows how to confirm the socket before ordering.
Socket and motherboard compatibility
The Xeon E5-2687W fits LGA 2011 in FCLGA2011 form. Single socket workstation boards with the C600 series controller carry it. The vendor list must show the exact E5-2687W string with Sandy Bridge-EP microcode, since workstation firmware differs from dual socket server releases.
At 150 W large workstation heatsinks with tower airflow apply. The Socket vs chipset: what decides whether a CPU works guide covers workstation pairing.
Memory, PCIe and cooling
Memory support is DDR3 at 800, 1066, 1333 or 1600 MT/s, four channels, with ECC. Workstation boards accept unbuffered ECC where the manual allows, plus registered DIMMs for large populations.
PCI Express is 40 lanes of PCIe 3.0 for workstation GPUs and fast storage. Single socket operation keeps all I/O local without NUMA hops.
Cooling is workstation grade for 150 W with a large tower heatsink. The square ILM mount needs LGA 2011 compatible brackets.
Upgrade paths
Within LGA 2011 the Xeon E5-2687W already tops the Sandy Bridge-EP workstation range, so the remaining path is Ivy Bridge-EP workstation parts where vendor lists allow. Memory, storage and the GPU carry over. A v2 comparison is Intel Xeon E5-2687W v2 on the same socket.
A platform move means a DDR4 workstation generation. Keep the node for creation duty where fast Sandy threads with ECC still work.
