A data center GPU against a workstation card, one Blackwell and one Turing: up to 192 GB HBM3e against 8 GB GDDR6, 19x the memory bandwidth on the B100, and NVLink 1,800 GB/s on the B100 where the RTX 4000 is PCIe only.

Median price per GPU per hour by billing type, with the cheapest listing under it.

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 on the RTX 4000: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
