HPE ProLiant Compute XD685 (HGX H200)
The eight-way XD685 in its NVIDIA HGX H200 configuration, the only one of the four HPE offers in both air-cooled and liquid-cooled form: 6U for air with accelerator kit S3P89A, 5U for direct liquid cooling with S4X53A. Two fifth-generation AMD EPYC processors drive it, from 32 to 96 cores and 280 to 400 W, across 24 DIMM slots with twelve channels per socket and up to 6 TB of DDR5-6400. Storage is eight EDSFF NVMe E3.S drives, or twelve with a storage controller, plus RAID-1 M.2 boot. No chassis part number is recorded because two apply depending on cooling, S4Q28A for air and S4R96A for liquid. HPE publishes no system power draw for the XD685, only twelve 3,000 W Titanium supplies with ten deployable, so nothing is summed here; the compute figures are NVIDIA's for the HGX H200 baseboard rather than an HPE claim.

Where a vendor states a basis, the figure shown is the dense one, and any figure it publishes is listed separately. Vendors commonly headline the sparse number instead: for NVIDIA's 2:4 structured sparsity that is exactly twice the dense figure, though other vendors' sparse modes do not all follow that ratio.

Frequently asked questions
How much does the ProLiant Compute XD685 (HGX H200) cost?
HPE sells the ProLiant Compute XD685 (HGX H200) on quote through OEMs and resellers, and nobody rents a whole one by the hour. Renting its 8 H200 accelerators separately at the cheapest live rate Flopper tracks, $2.09 per GPU-hour across 21 providers, comes to about $16.72 an hour for the equivalent capacity.

How much power does the ProLiant Compute XD685 (HGX H200) require?
HPE has not published a power figure for the ProLiant Compute XD685 (HGX H200), and Flopper does not derive one from the accelerator count because the rest of the system draws power too.
How many GPUs are in the ProLiant Compute XD685 (HGX H200)?
8. The ProLiant Compute XD685 (HGX H200) carries 8 NVIDIA H200 SXM 141GB accelerators in a rack form factor, and every throughput figure on this page is the total across them. H200 specifications →
