What the Xeon Platinum 8380 is

The Xeon Platinum 8380 is a 40-core server processor that Intel released in April 2021 at the top of the Ice Lake-SP range for 2-socket systems. Its Sunny Cove cores run 2.3 GHz base to 3.4 GHz turbo with Hyper-Threading for 80 threads per socket. Cache is 60 MB with 1.25 MB of L2 per core.

The chip holds the highest core count of its generation for 2-socket nodes, with 160 threads per system. The 3.0 GHz all core turbo keeps parallel work moving across all sockets. The 10 nm process pairs 8 channels of DDR4-3200 with 64 PCIe 4.0 lanes.

There is no integrated graphics on this model, so setup relies on board BMC graphics. ECC memory support guards data across long uptime. The socket package is FCLGA4189 at 77.5 × 56.5 mm.

Socket and motherboard compatibility

The 8380 fits the LGA 4189 socket on Whitley boards for Ice Lake-SP. Cedar Island boards for Cooper Lake share the socket name but do not accept this chip, and the Cooper 8380H twin is a different 28-core part, so confirm the model without suffix before ordering. The server vendor CPU support list names the exact boards for Platinum parts.

Two-socket operation is the design point for Xeon Platinum dual processor parts, with single socket boards possible where the vendor qualifies them. A buyer building top 2-socket nodes should confirm power delivery for 270 W parts before ordering.

Check memory population rules for 2-socket boards when ordering. Sixteen DIMM slots per socket is the platform shape, and both sockets should match in capacity and speed.

Memory, PCIe and cooling

The memory controller supports DDR4 up to 3200 MT/s in 8 channels, up to 4 TB per socket, with ECC support. Top nodes use RDIMM pairs across all channels for bandwidth with integrity. The controller does not accept DDR5.

The CPU supplies 64 PCIe 4.0 lanes per socket for network cards and NVMe storage. Two-socket boards split lanes across slots and onboard controllers, so the board specifications state which slots reach full speed. Three UPI links at 11.2 GT/s carry socket to socket traffic.

At 270 W, vendor-qualified liquid or top performance air heatsinks with strong directed chassis airflow are needed. Mounting is board specific with no retail pattern, and the CPU cooler compatibility by socket guide explains why server sockets list no desktop bracket.

Upgrade paths

Against the Intel Xeon Platinum 8368, the 8380 adds cores and cache at the same power. The 38-core part suits dense hosts, while this 40-core part suits top scale out nodes. Both share Whitley boards and DDR4-3200 limits.

Moving to LGA 4677 needs new boards and DDR5 memory for Sapphire Rapids generations. The 8380 fits a flagship virtual farm, a top cloud node, or a large analytics system with extreme threads.

For used buyers, the top Ice Lake Platinum makes sense when thread density leads. Note the Cooper twin Intel Xeon Platinum 8380H is a different 28-core chip on Cedar Island boards, so match the platform before buying used.
