Gigabyte G593-SD1-LAX3 vs Supermicro GPU SuperServer SYS-821GE-TNHR
Both are built on the NVIDIA HGX H200 baseboard, so their accelerator performance is identical rather than merely similar. The choice between them is chassis, cooling, expansion and supplier, not FLOPS.

Gigabyte G593-SD1-LAX3
A 5U direct-liquid-cooled server carrying the NVIDIA HGX H200 baseboard with eight SXM GPUs, connected at 900 GB/s by NVLink and NVSwitch. Both CPUs and GPUs are liquid cooled, which is what lets Gigabyte fit the platform into 5U rather than the 8U an air-cooled equivalent needs. Two LGA 4677 sockets take 5th or 4th generation Intel Xeon Scalable processors or the Xeon CPU Max series, with 32 DIMM slots across eight DDR5 channels, eight Gen5 NVMe bays, twelve PCIe Gen5 x16 slots and BlueField-3 DPU compatibility. Power comes from four plus two redundant 3000 W Titanium supplies. It weighs 91 kg net and orders as 6NG593SD1DR000LBX3. Note that Gigabyte's page quotes "over 32 petaflops of FP8 deep learning compute" for an eight-way HGX H200; that is NVIDIA's own marketing figure for the baseboard rather than a Gigabyte measurement, and it is the sparse number. The dense figures shown here are NVIDIA's for the same baseboard, and they are what this site publishes throughout.

8U GPU SuperServer built on the NVIDIA HGX H200 baseboard with 4x NVSwitch. Two Intel Xeon Scalable sockets (4th or 5th Gen, up to 64 cores each at 350W, air-cooled), 32 DIMM slots to an 8 TB maximum of DDR5-5600 ECC RDIMM, 19 front hot-swap 2.5-inch NVMe/SATA bays plus two M.2 NVMe boot slots, and 8x PCIe Gen5 x16 low-profile slots with 2x FHHL. Also sold in an HGX H100 configuration. System-level power draw is not published.
