What each one runs, and what a million tokens costs
Weights + KV cache at 8K context + overhead against 90% of each card's memory. Where a model needs more than one card the cell says how many and prices the set at today's median. $/M tokens is the hourly median divided by estimated single-stream output, from memory bandwidth — an estimate for ranking, not a benchmark.

Buy or rent?
Hours of renting at today's median that add up to the card's approximate list price. List prices are typical quoted figures, not tracked, and do not include the server, power or the person to run it — so the break-even is a floor, not a verdict.
Questions
Is the H100 SXM or the A100 80GB cheaper to rent?
On 2026-09-18 the H100 SXM has a market median of $3.50 per GPU-hour across 46 providers and the A100 80GB $1.79 across 37, so the A100 80GB is 49% cheaper per hour. Among the 35 providers that price both, the H100 SXM is cheaper at 2 and the A100 80GB at 33. Per hour is only half the answer — the table below prices a whole model on each.
Which should I rent for a 70B model?
At 4-bit, Llama 3.1 70B needs about 44.5 GB. On the H100 SXM that is one card at $3.50/hr; on the A100 80GB one card at $1.79/hr. Estimated single-stream decode is ~68 vs ~41 tokens per second, from memory bandwidth.
What is the real difference between them?
80 GB HBM3 at 3,350 GB/s (Hopper) against 80 GB HBM2e at 2,039 GB/s (Ampere). Memory decides what fits; bandwidth decides how fast it generates, because each token streams the active weights once. Compute matters for prompt processing and training, not for how fast text appears.
