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.

Frequently asked questions
How much does the GPU SuperServer SYS-821GE-TNHR cost?
Supermicro sells the GPU SuperServer SYS-821GE-TNHR on quote through OEMs and resellers, and nobody rents a whole one by the hour. Renting its 8 H200 accelerators separately at the cheapest live rate Flopper tracks, $2.09 per GPU-hour across 21 providers, comes to about $16.72 an hour for the equivalent capacity.

How much power does the GPU SuperServer SYS-821GE-TNHR require?
Supermicro has not published a power figure for the GPU SuperServer SYS-821GE-TNHR, and Flopper does not derive one from the accelerator count because the rest of the system draws power too.
How many GPUs are in the GPU SuperServer SYS-821GE-TNHR?
8. The GPU SuperServer SYS-821GE-TNHR carries 8 NVIDIA H200 SXM 141GB accelerators in a rack form factor, and every throughput figure on this page is the total across them. H200 specifications →
