NVIDIA HGX Rubin NVL8
Eight Rubin SXM on an HGX baseboard, listed by NVIDIA alongside HGX B300 and HGX B200. NVIDIA publishes NVFP4 twice and the two are different workloads, not a sparse/dense pair: inference 400 PFLOPS sparse, training 280 PFLOPS dense. FP8/FP6 training is 140 PFLOPS dense. System power is not published for the baseboard; the 24 kW figure on DGX Rubin NVL8 is the full chassis including CPUs. NVIDIA marks the specification preliminary.

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 HGX Rubin NVL8 cost?
NVIDIA sells the HGX Rubin NVL8 on quote through OEMs and resellers, and Flopper has no live rental listing for its Rubin accelerator to derive an hourly figure from. System rental pricing →
How much power does the HGX Rubin NVL8 require?
NVIDIA has not published a power figure for the HGX Rubin NVL8, 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 HGX Rubin NVL8?
8. The HGX Rubin NVL8 carries 8 NVIDIA Rubin SXM accelerators in a baseboard form factor, and every throughput figure on this page is the total across them. Rubin specifications →
