Inventec P5800G7 vs NVIDIA DGX B300
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.

Inventec P5800G7
Inventec's densest Blackwell Ultra node: the same eight-accelerator HGX B300 NVL8 baseboard as its 10U air-cooled sibling, folded into 5U at 448 by 219.5 by 875 mm by moving to liquid cooling. The fan count tells the story, four 80 mm GPU fans against fifteen in the air-cooled machine. East-west networking is eight 800Gb OSFP connectors driven by NVIDIA ConnectX-8 SuperNICs, one per accelerator, and hosts are Intel Xeon 6700 series with E-cores or 6700 and 6500 series with P-cores. Power is 3,300 W 54 V supplies in 4+1 or 4+2 redundancy with a 2,000 W 12 V host plane. This is the only Inventec node whose GPU count is stated on the page, in the NVL8 designation itself. No throughput, memory or system power figure is published.
Vendor product pageNVIDIA DGX B300
Eight Blackwell Ultra SXM GPUs on the HGX B300 baseboard with Intel Xeon 6776P processors, in a 10U chassis. NVIDIA quotes 144 PFLOPS of FP4 inference performance for this machine, which is the sparse figure; the dense equivalent is 108 PFLOPS, and both are recorded. Power is given by NVIDIA as approximately 14 kW.
