Inventec P5800G7 vs Lenovo ThinkSystem SR680a V4
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 pageLenovo ThinkSystem SR680a V4
Lenovo's Blackwell Ultra machine, an 8U server developed in-house around eight NVIDIA HGX B300 SXM GPUs and two Intel Xeon 6700P processors reaching 86 cores at up to 350 W. Notably it is designed for air cooling, where most B300 machines in this catalogue are liquid cooled or need direct-to-chip plumbing, and it carries that with 21 hot-swap fans, six at the front for CPUs and memory and fifteen at the rear for drives and the GPU subsystem. Power is six or eight hot-swap supplies, either 3,200 W AC or 3,800 W high-voltage AC or DC, in N+1 or N+N redundancy. The chassis is 447 by 351 by 924 mm at up to 124.7 kg, the heaviest of Lenovo's 8U accelerator servers. Lenovo publishes no system power draw, no accelerator memory total and no system throughput figure; its per-GPU B300 table matches NVIDIA's own specification for the baseboard, which is linked here.
