Fujitsu PRIMERGY GX2570 M8s (Air-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 (Air-Cooled)
The air-cooled member of Fujitsu's PRIMERGY GX2570 M8s pair, sold by Fsas Technologies, the renamed Fujitsu server business. A 10U chassis carries one NVIDIA HGX B200 8-GPU baseboard holding eight B200 SXM modules at 180 GB apiece, interconnected by NVSwitch, for 1.44 TB of GPU memory. Hosting is two Intel Xeon 6900P processors reaching 128 cores and 256 threads, with 24 DIMM slots taking up to 6 TB of DDR5 at 6400 MT/s or MRDIMM at 8800. Storage is ten hot-plug 2.5 inch NVMe bays plus two internal M.2, and expansion is two full-height half-length and ten low-profile PCIe 5.0 x16 slots. The machine measures 449 by 843.3 by 438.8 mm and weighs up to 133 kg with rails, drawing from six 5,250 W Titanium supplies in 3+3 redundancy. Fujitsu publishes no throughput figure and no system power draw; performance figures for the baseboard are on the linked HGX B200 entry.
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.
