Fujitsu PRIMERGY GX2570 M8s (Liquid-Cooled) vs Penguin Solutions Altus XE4318GTS-DTC
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.
Vendor product pagePenguin Solutions Altus XE4318GTS-DTC
The Penguin Solutions Altus XE4318GTS-DTC is a 4U GPU server carrying eight NVIDIA HGX B200 SXM modules of 180 GB each, hosted by AMD EPYC 9005/9004 Series processors with 8x PCIe Gen5 x16 FHHL and 4x PCIe Gen5 x16 FHHL double-width. The DTC suffix marks Penguin's direct-to-chip liquid cooling, which is what folds an eight-accelerator Blackwell baseboard into 4U where the air-cooled equivalent needs 8U. Penguin publishes only rack height, host processor, expansion slots and the accelerator for its servers, so no power draw, total memory, interconnect bandwidth or throughput figure is shown here; its full datasheets are hosted off its own domain and were not used as a source.
