Not as fast as the L40S, but Runpod.io has the A40 48gb for $0.28/hr spot price, so if its mainly VRAM you need, this is a lot cheaper option. Vast.ai has it for the same price as well.
Runpod is definitely cheaper than we are! We are not the cheapest GPU/hour you can get on any hardware iteration. That's not what we're about, and it is 100% legit to point out that there are workloads that make more sense on other platforms. It would be very weird if that wasn't the case.
