Inventec P9000AG7 (AC) vs Lenovo ThinkSystem SR780a V3 (HGX B200)
Both are built on the NVIDIA HGX B200 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 P9000AG7 (AC)
Inventec's air-cooled Blackwell node on AMD hosts, a 10U chassis 448 by 441 by 850 mm carrying one NVIDIA HGX B200 baseboard alongside fifth-generation AMD EPYC processors of up to 400 W. Storage is eight U.2 NVMe bays from the PCIe switch plus four more from the CPU and two M.2, and the switch also provides eight low-profile PCIe Gen5 x16 slots. Cooling is air, with fifteen 80 mm fans on the GPU side and five on the CPU side, and power comes from 3,300 W 54 V supplies in 4+2 redundancy for the accelerators with a separate 2,400 W 12 V plane in 1+1 for the host. Inventec publishes no throughput, memory or system power figure for the node; the baseboard's figures are on the linked HGX B200 entry. The GPU count is not stated on the page either, and is taken from NVIDIA's designation of HGX B200 as an eight-GPU baseboard.
Vendor product pageLenovo ThinkSystem SR780a V3 (HGX B200)
The Blackwell configuration of Lenovo's SR780a V3, ordered under base feature code C695 and built on a ThinkSystem NVIDIA HGX B200 180GB eight-GPU liquid-cooled board rated at 1000 W per accelerator, against 700 W for the Hopper board in the same chassis. That is the case for the design: sixth generation Lenovo Neptune water cooling on four loops takes CPUs, GPUs and NVLink switches, removing up to 75 percent of the heat in warm water, and eight kilowatt-class accelerators still fit in 5U where the air-cooled machines in this catalogue need 8U or 10U. The chassis is 447 by 219 by 942 mm at up to 92 kg, hosted by two fifth-generation Intel Xeon Scalable processors at 56 cores and 350 W, with eight hot-swap supplies in N+N redundancy. Lenovo publishes no system power draw, no accelerator memory total and no system-level throughput; the linked HGX B200 entry carries NVIDIA's figures.
