Nvidia P40 vs Nvidia V100S

Two Nvidia data center GPUs, one Pascal and one Volta: 24 GB GDDR5 against 32 GB HBM2, 3.3x the memory bandwidth on the V100S, and NVLink 300 GB/s on the V100S where the P40 is PCIe only.

Price comparison

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

Billing	P40	V100S	Difference
On-demand	No on-demand listings	-- /GPU/hr from $0.88
Spot	-- /GPU/hr from $0.07	No spot listings

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 spot on the P40 and on-demand on the V100S: we only show one when at least 3 providers list the GPU on that billing type. Verify before provisioning. More on how we price.
