Which is cheaper per hour, H100 SXM or A100 SXM4?
A100 SXM4 is cheaper. It settles at $0.90 per GPU-hour against $2.86 for the H100 SXM as of October 6, 2026, a gap of $1.96 per GPU-hour, $47.04 per GPU-day, or about $1411.20 per GPU over a 30-day month.
How has the H100 SXM premium over A100 SXM4 moved over 30 days?
Thirty days earlier the H100 SXM settled at $3.07 and the A100 SXM4 at $1.06, a spread of $2.01 per GPU-hour. As of October 6, 2026 it is $1.96, so the H100 SXM premium has narrowed by $0.05.
Which is cheaper per GB of memory capacity, H100 SXM or A100 SXM4?
A100 SXM4 is cheaper per GB. Dividing the settled hourly price by on-board memory, the H100 SXM (80 GB HBM3) costs $0.0357 per GB of capacity per hour and the A100 SXM4 (80 GB HBM2e) $0.0112, as of October 6, 2026. Capacity only: memory type and bandwidth differ (HBM2e, HBM3, HBM3e), so this is not a throughput comparison.
When does the H100 SXM pay off over the A100 SXM4?
At current settles the H100 SXM costs 3.2× the A100 SXM4 per hour, so it pays off only on work where it gets through more than 3.2× as much per hour as the A100 SXM4; below that, the A100 SXM4 finishes the same job for less. Both carry 80 GB of memory, so the premium buys no extra memory capacity; it is paid back only through faster work. Ornn publishes prices, not benchmarks: test the throughput ratio on your own workload.
Where can I rent H100 SXM or A100 SXM4 GPUs?
Ornn Compute (compute.ornn.com) reserves dedicated NVIDIA H100 SXM and NVIDIA A100 SXM4 capacity across verified neocloud providers, priced against the same settled OCPI-H100 and OCPI-A100 indices published on this page, with access in minutes. Reservations can be resold on a secondary market if requirements change, so unused capacity is recoverable rather than sunk. Ornn both prices compute and rents it.
