Gigabyte G593-SD1-LAX3 vs Supermicro GPU SuperServer AS -8125GS-TNHR (HGX H200)
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.
Vendor product pageSupermicro GPU SuperServer AS -8125GS-TNHR (HGX H200)
Supermicro's 8U AMD EPYC platform for the NVIDIA HGX H200 8-GPU baseboard, and the EPYC sibling of the Intel-based SYS-821GE-TNHR. Two SP5 sockets take AMD EPYC 9004 processors up to 128 cores and 256 threads at up to 400 W each, air cooled, with 24 DIMM slots supporting up to 6 TB of DDR5. GPUs connect to the CPUs over PCIe 5.0 x16 and to each other over NVLink with NVSwitch, and the chassis provides eight NICs for GPU-direct RDMA at a 1:1 ratio with the GPUs. The CSE-GP801TS chassis is 8U, weighs 102.1 kg gross, takes up to ten heavy-duty fans and six 3000 W Titanium supplies in 3+3 redundancy. Compute is identical to the H100 configuration because H100 and H200 are the same silicon at the same clocks; the difference is memory, 1.128 TB of HBM3e here against 0.64 TB. Supermicro publishes no FLOPS figure for this system; the compute shown is NVIDIA's for the HGX H200 baseboard it carries. Supermicro publishes no system power draw either, only the supply configuration, so total power is left blank.
