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 Helios cost?
AMD sells the Helios on quote through OEMs and resellers, and Flopper has no live rental listing for its Instinct MI455X accelerator to derive an hourly figure from. System rental pricing →
How much power does the Helios require?
AMD has not published a power figure for the Helios, 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 Helios?
72. The Helios carries 72 AMD Instinct MI455X accelerators in a rack form factor, and every throughput figure on this page is the total across them. Instinct MI455X specifications →
