Two Nvidia data center GPUs, one Blackwell and one Turing: up to 192 GB HBM3e against 16 GB GDDR6, 25x the memory bandwidth on the B100, and NVLink 1,800 GB/s on the B100 where the T4G is PCIe only.

Price comparison
Median price per GPU per hour by billing type, with the cheapest listing under it.
| Billing | B100 | T4G | Difference |
|---|---|---|---|
| On-demand | No on-demand listings | -- /GPU/hr from $0.42 | |
| Reserved | No reserved listings | -- /GPU/hr from $0.18 (36 mo) |
Heads up: A provider's own page may quote a different figure, for example on tax, region or a promotion. A monthly-only plan shows a derived hourly rate. Medians are across providers, one vote each, so a large catalog does not outweigh a small one. No median for on-demand and reserved on the T4G: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
