Fujitsu PRIMERGY GX2570 M8s (Liquid-Cooled) 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.

Fujitsu PRIMERGY GX2570 M8s (Liquid-Cooled)

The liquid-cooled member of Fujitsu's PRIMERGY GX2570 M8s pair, and the same NVIDIA HGX B200 8-GPU baseboard as the air-cooled model compressed from 10U into 4U. Eight B200 SXM modules at 180 GB apiece are interconnected by NVSwitch for 1.44 TB of GPU memory, hosted by two Intel Xeon 6900P processors with 24 DIMM slots taking up to 6 TB. Liquid cooling costs two of the ten NVMe bays, leaving eight, and the chassis measures 449 by 895.4 by 174 mm at up to 80 kg with rails, which is 53 kg lighter than the air-cooled build. Power comes from four 6,600 W Titanium supplies in 2+2 redundancy. Fujitsu notes that a CDU, manifolds and a liquid-cooling rack must be purchased separately. No throughput figure and no system power draw are published; baseboard performance is on the linked HGX B200 entry.

Lenovo 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.
