Which cloud GPU gives the most compute per dollar?

The most compute per dollar today is the AMD Instinct MI300X: $2.06 per petaFLOP-hour (BF16 dense) at its $2.69/GPU-hr median.

• Top value today: AMD Instinct MI300X $2.06/PFLOP-hr · NVIDIA B200 $2.90/PFLOP-hr · NVIDIA RTX 4090 $3.42/PFLOP-hr · NVIDIA H100 PCIe $3.44/PFLOP-hr · NVIDIA RTX A6000 $3.68/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.
