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.

The eight-GPU Blackwell Ultra baseboard OEMs build around. NVIDIA publishes both a dense and a sparse figure for every tensor precision here, and for FP4 the two are not a factor of two apart: dense rose by half over the B200, from 72 to 108 PFLOPS, while sparse stayed at 144. Total memory is NVIDIA's own 2.1 TB rather than the 2.304 TB that eight 288 GB GPUs would suggest. Memory bandwidth of 64 TB/s is the one derived number, being eight times the B300's published 8 TB/s, because NVIDIA gives no board-level HBM figure. No INT8 row is recorded: NVIDIA's table gives 3 POPS sparse for this board while our B300 chip entry implies 36 POPS dense, the two cannot both be right, and the question is open rather than guessed at. NVIDIA publishes no baseboard power figure, so total power is blank.
