What the Xeon Platinum 8360HL is

The Xeon Platinum 8360HL 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 HL suffix unlocks the large DDR memory tier up to 4.5 TB per socket, against 1.12 TB on the plain H twin. The clocks, cache and power match the Intel Xeon Platinum 8360H exactly, so the suffix buys memory headroom rather than speed. 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 8360HL 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 HL suffix parts.

Eight-socket operation is the design point for Xeon Platinum HL parts, since large memory tiers span sockets. A buyer planning an in-memory database should confirm the board supports the 4.5 TB tier with the needed DIMM and Optane mix before ordering.

Check memory population rules for large tier boards when ordering. Twelve DIMMs per socket is the platform shape, and the large tier needs the vendor qualified DIMM and persistent memory mix.

Memory, PCIe and cooling

The memory controller supports DDR4 up to 3200 MT/s in 6 channels with ECC support, reaching the 4.5 TB tier per socket with the qualified mix. In-memory database nodes use the large tier to hold whole data sets beside the cores. 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 8360H, the 8360HL adds only the large memory tier with identical clocks. The plain H part suits nodes under 1.12 TB per socket at lower cost, while this HL part suits databases that must hold terabytes beside the cores. Both share Cedar Island boards.

Moving to LGA 4677 needs new boards and DDR5 memory for Sapphire Rapids generations. The 8360HL fits an 8-socket in-memory database, a large cache tier, or an analytics node with huge working sets.

For used buyers, the HL part makes sense only when the workload fills the large tier. When memory stays small, the plain H twin gives the same speed for less on the same platform.

Frequently asked questions

What socket does the Intel Xeon Platinum 8360HL use?

It uses LGA 4189 on Cedar Island boards for Cooper Lake. Whitley Ice Lake boards share the socket name but do not accept it.

How many cores does the Intel Xeon Platinum 8360HL have?

24 cores with 48 threads, 3.0 GHz base and up to 4.2 GHz turbo, with 33 MB of Intel Smart Cache.

What memory does the Intel Xeon Platinum 8360HL support?

DDR4 up to 3200 MT/s with ECC in 6 channels, up to 4.5 TB per socket with the qualified mix.

What is the difference between the 8360HL and the 8360H?

The HL unlocks the 4.5 TB large memory tier per socket. The plain H twin holds the same clocks with up to 1.12 TB.

What is the TDP of the Intel Xeon Platinum 8360HL?

225 W. Performance air or liquid heatsinks with strong directed chassis airflow are needed.
