HPE ProLiant Compute XD685 (HGX H200) vs Supermicro GPU SuperServer AS -8125GS-TNHR (HGX H200)
Both are built on the NVIDIA HGX H200 baseboard, so their accelerator performance is identical rather than merely similar. The choice between them is chassis, cooling, expansion and supplier, not FLOPS.

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.
Vendor product pageSupermicro GPU SuperServer AS -8125GS-TNHR (HGX H200)
Supermicro's 8U AMD EPYC platform for the NVIDIA HGX H200 8-GPU baseboard, and the EPYC sibling of the Intel-based SYS-821GE-TNHR. Two SP5 sockets take AMD EPYC 9004 processors up to 128 cores and 256 threads at up to 400 W each, air cooled, with 24 DIMM slots supporting up to 6 TB of DDR5. GPUs connect to the CPUs over PCIe 5.0 x16 and to each other over NVLink with NVSwitch, and the chassis provides eight NICs for GPU-direct RDMA at a 1:1 ratio with the GPUs. The CSE-GP801TS chassis is 8U, weighs 102.1 kg gross, takes up to ten heavy-duty fans and six 3000 W Titanium supplies in 3+3 redundancy. Compute is identical to the H100 configuration because H100 and H200 are the same silicon at the same clocks; the difference is memory, 1.128 TB of HBM3e here against 0.64 TB. Supermicro publishes no FLOPS figure for this system; the compute shown is NVIDIA's for the HGX H200 baseboard it carries. Supermicro publishes no system power draw either, only the supply configuration, so total power is left blank.
