Fujitsu PRIMERGY GX2580 M8s vs Penguin Solutions Relion XE4418GTS-DTC

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.

Fujitsu PRIMERGY GX2580 M8s

Fujitsu's Blackwell Ultra machine, built on one NVIDIA SXM HGX B300 8-GPU baseboard integrating eight Blackwell Ultra SXM modules. Networking is the notable part: eight NVIDIA ConnectX-8 OSFP ports at 800GbE apiece, one per accelerator, so scale-out matches the baseboard rather than bottlenecking it. Hosting is two Intel Xeon 6700 or 6500P processors reaching 86 cores and 172 threads, with 32 DIMM slots taking up to 8 TB of DDR5-6400. Storage is eight hot-plug E1.S NVMe bays holding up to 123 TB plus two M.2 devices, and there are two front full-height half-length PCIe 5.0 x16 slots. The 8U chassis measures 483 by 980 by 356 mm and weighs up to 137 kg with rails, drawing from six 6,600 W Titanium supplies in 3+3 redundancy. Fujitsu states no total GPU memory, no throughput figure and no system power draw; baseboard performance is on the linked HGX B300 entry.

Penguin Solutions Relion XE4418GTS-DTC

The Penguin Solutions Relion XE4418GTS-DTC is a 4U GPU server carrying eight NVIDIA HGX B300 SXM6 modules of 288 GB each, hosted by Intel Xeon 6 (6700/6500 Series) processors with 4x PCIe Gen5 x16 FHHL double-width. Direct-to-chip liquid cooling puts a full Blackwell Ultra baseboard in 4U, half the height of Penguin's air-cooled B300 machine. 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.
