Supermicro 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.

Where a vendor states a basis, the figure shown is the dense one, and any figure it publishes is listed separately. Vendors commonly headline the sparse number instead: for NVIDIA's 2:4 structured sparsity that is exactly twice the dense figure, though other vendors' sparse modes do not all follow that ratio.
