Dell PowerEdge XE9680 vs HPE ProLiant Compute XD685 (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.

Dell PowerEdge XE9680
6U rack server built on the NVIDIA HGX H200 baseboard. Two Intel Xeon Scalable sockets (4th or 5th Gen, up to 64 cores each), 32 DDR5 DIMM slots to a 4 TB maximum, and 2800W Titanium redundant hot-swap power supplies. The same chassis is also orderable with 8x H100 80GB, 8x AMD Instinct MI300X 192GB or 8x Intel Gaudi3 128GB; Dell does not list a B200 option. System-level power draw is not published, so only the baseboard figure on the HGX H200 reference page is authoritative.
Vendor product pageHPE 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.
