Lenovo ThinkSystem SR680a V4 vs Penguin Solutions Relion XE8418GTS
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.

Lenovo ThinkSystem SR680a V4
Lenovo's Blackwell Ultra machine, an 8U server developed in-house around eight NVIDIA HGX B300 SXM GPUs and two Intel Xeon 6700P processors reaching 86 cores at up to 350 W. Notably it is designed for air cooling, where most B300 machines in this catalogue are liquid cooled or need direct-to-chip plumbing, and it carries that with 21 hot-swap fans, six at the front for CPUs and memory and fifteen at the rear for drives and the GPU subsystem. Power is six or eight hot-swap supplies, either 3,200 W AC or 3,800 W high-voltage AC or DC, in N+1 or N+N redundancy. The chassis is 447 by 351 by 924 mm at up to 124.7 kg, the heaviest of Lenovo's 8U accelerator servers. Lenovo publishes no system power draw, no accelerator memory total and no system throughput figure; its per-GPU B300 table matches NVIDIA's own specification for the baseboard, which is linked here.

The Penguin Solutions Relion XE8418GTS is a 8U 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. The air-cooled Blackwell Ultra machine, twice the height of its direct-to-chip sibling for the same eight accelerators. 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.
