Which cloud GPU gives the most compute per dollar?

The most compute per dollar today is the AMD Instinct MI300X: $2.29 per petaFLOP-hour (BF16 dense) at its $2.99/GPU-hr median.

• Top value today: AMD Instinct MI300X $2.29/PFLOP-hr · NVIDIA RTX 3090 $2.82/PFLOP-hr · NVIDIA RTX 4090 $3.06/PFLOP-hr · NVIDIA B200 $3.23/PFLOP-hr · NVIDIA A100 40GB PCIe $3.69/PFLOP-hr.
• Throughput figures are dense (no-sparsity) BF16 tensor TFLOPS from vendor datasheets — the 2× 'with sparsity' marketing numbers are excluded.
• SKUs without a vendor-published figure we can stand behind are left out rather than estimated.
• $/PFLOP-hr is the cross-generation comparison: newer cards often cost more per hour but less per unit of work.
