Inventec P9000G7 (AC) 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 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.
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.
