HPE ProLiant Compute XD685 (HGX B300) vs Inventec P9000G7 (AC)
Both are built on the NVIDIA HGX B300 8-GPU 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 B300)
The eight-way XD685 in its NVIDIA HGX B300 configuration, which requires the high-power liquid-cooled chassis S6Y07A rather than the standard DLC one. This is the denser sibling of the air-cooled XD690, which reaches the same eight Blackwell Ultra GPUs in 10U where this does it in 5U. Two fifth-generation AMD EPYC processors, 24 DIMM slots and up to 6 TB of DDR5-6400, eight EDSFF NVMe E3.S drives. HPE publishes no system power draw for the XD685, only twelve 3,000 W Titanium supplies with ten deployable, so unlike the XD690 no figure is recorded; the compute shown is NVIDIA's specification for the HGX B300 baseboard rather than an HPE claim.
Vendor product pageInventec P9000G7 (AC)
The Blackwell Ultra generation of Inventec's 10U air-cooled node, in the same 448 by 441 by 850 mm chassis as its B200 sibling but hosted by Intel Xeon 6700 series with E-cores or 6700 and 6500 series with P-cores. It carries one NVIDIA HGX B300 baseboard and eight 800Gb OSFP connectors for east-west networking, one per accelerator. Storage is eight U.2 NVMe bays with four optional more and two M.2. The accelerator power plane moves to 3,300 W supplies in 5+1 redundancy, tighter than the B200 node's 4+2, with a 2,000 W 12 V host plane. Inventec publishes no throughput, memory or system power figure; the linked HGX B300 entry carries NVIDIA's. The GPU count is not stated and is taken from NVIDIA's designation of HGX B300 as an eight-GPU baseboard.
