What the Xeon Platinum 8360H is
The Xeon Platinum 8360H is a 24-core server processor that Intel released in September 2020 with the Cooper Lake-SP range for 8-socket systems. Its Skylake-SP cores run 3.0 GHz base to 4.2 GHz turbo with Hyper-Threading for 48 threads. Cache is 33 MB of Intel Smart Cache with 1 MB of L2 per core.
The chip pairs high core count with a strong 3.0 GHz base at 225 W for dense multi-socket work. The 4.2 GHz burst helps single thread tasks that stall on slower cores. The 14 nm process carries bfloat16 instructions for inference work through Deep Learning Boost.
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 8360H fits the LGA 4189 socket on Cedar Island boards for Cooper Lake. Whitley boards for Ice Lake-SP share the socket name but do not accept this chip, so the board generation must match the processor generation. The server vendor CPU support list names the exact boards for H suffix parts.
Eight-socket operation is the design point for Xeon Platinum H parts, with smaller configurations possible where the vendor qualifies them. A buyer scaling past four sockets must choose Platinum, since Gold H parts stop at four. Confirm power delivery for 225 W parts before ordering.
Check memory population rules for large boards when ordering. Twelve DIMMs per socket is the platform shape, and all sockets should match in capacity and speed.
Memory, PCIe and cooling
The memory controller supports DDR4 up to 3200 MT/s in 6 channels, up to 1.12 TB per socket, with ECC support. Dense multi-socket builds use RDIMM pairs across all channels for bandwidth with integrity. Optane persistent memory is a board option on qualifying platforms.
The CPU supplies 48 PCIe 3.0 lanes per socket for network cards and NVMe storage. Multi-socket boards split lanes across slots and onboard controllers, so the board specifications state which slots reach full speed. Six UPI links at 10.4 GT/s carry socket to socket traffic.
At 225 W, vendor-qualified performance air or liquid 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 8360HL, the 8360H trades the large memory tier for lower cost with identical clocks. The HL part suits databases past 1.12 TB per socket, while this H part suits dense compute under that line. Both share Cedar Island boards.
Moving to LGA 4677 needs new boards and DDR5 memory for Sapphire Rapids generations. The 8360H fits an 8-socket virtual farm, a large analytics system, or a cloud node with heavy threads.
For used buyers, the 24-core H part makes sense when thread density leads. When clocks matter most, the 8-core 8356H gives higher bases on the same platform.
