What the Xeon E5-1650 is
Intel Xeon E5-1650 is a six core Sandy Bridge-E server processor that Intel released in March 2012 for single socket workstations. It runs at 3.2 GHz base with turbo to 3.8 GHz, with 12 MB cache and Hyper-Threading for 12 threads. Power is rated at 130 W on a 32 nm process. Six fast cores with quad channel memory made it the single socket workstation favorite for threaded 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. The wide turbo range covers both all core renders and single threaded modeling tasks.
Workstation towers pair it with 16 GB to 64 GB of ECC DDR3 and a professional GPU. All core loads sit near 3.2 GHz, while lightly threaded work reaches 3.8 GHz. The LGA, PGA and BGA: CPU package types explained guide contrasts this large socketed server part with soldered designs.
Socket and motherboard compatibility
The Xeon E5-1650 fits LGA 2011 in FCLGA2011 form. Single socket workstation boards with the C600 series controller carry it, and X79 enthusiast boards accept E5-1600 parts under the Sandy Bridge-E support entry. The vendor list must include the exact E5-1650 string.
At 130 W large workstation heatsinks 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. Four populated channels feed twelve threads with high bandwidth for renders.
PCI Express is 40 lanes of PCIe 3.0 for workstation GPUs and fast storage. Single socket layouts keep all I/O local without NUMA hops.
Cooling uses workstation tower heatsinks for 130 W. The square ILM needs LGA 2011 brackets.
Upgrade paths
On LGA 2011 the Xeon E5-1650 can step to faster Sandy Bridge-E or Ivy Bridge-E six core parts on the same board, where vendor lists allow. Memory, storage and the GPU carry over. A higher cache step is Intel Xeon E5-1660 on the same socket.
A platform move means a DDR4 workstation generation. Keep the node for threaded creation duty.
Frequently asked questions
What socket does the Intel Xeon E5-1650 use?
It uses LGA 2011. Single socket workstation boards carry it.
Is the Xeon E5-1650 for dual socket boards?
No. The 1600 numbering is single socket only.
