Which is cheaper per hour, B200 or A100 SXM4?
A100 SXM4 is cheaper. It settles at $0.90 per GPU-hour against $7.56 for the B200 as of October 6, 2026, a gap of $6.66 per GPU-hour, $159.84 per GPU-day, or about $4795.20 per GPU over a 30-day month.
How has the B200 premium over A100 SXM4 moved over 30 days?
Thirty days earlier the B200 settled at $6.64 and the A100 SXM4 at $1.06, a spread of $5.58 per GPU-hour. As of October 6, 2026 it is $6.66, so the B200 premium has widened by $1.08.
Which is cheaper per GB of memory capacity, B200 or A100 SXM4?
A100 SXM4 is cheaper per GB. Dividing the settled hourly price by on-board memory, the B200 (180 GB HBM3e) costs $0.0420 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 B200 pay off over the A100 SXM4?
At current settles the B200 costs 8.4× the A100 SXM4 per hour, so it pays off only on work where it gets through more than 8.4× as much per hour as the A100 SXM4; below that, the A100 SXM4 finishes the same job for less. The B200 also carries 2.3× the memory (180 GB HBM3e against 80 GB HBM2e); where memory capacity rather than GPU count sets the job size, compare cost per job, not per GPU-hour. Ornn publishes prices, not benchmarks: test the throughput ratio on your own workload.
Where can I rent B200 or A100 SXM4 GPUs?
Ornn Compute (compute.ornn.com) reserves dedicated NVIDIA B200 and NVIDIA A100 SXM4 capacity across verified neocloud providers, priced against the same settled OCPI-B200 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.
