B200 vs RTX A4000: common questions

Is the B200 or the RTX A4000 cheaper to rent?

On Aquanode's live marketplace the B200 starts at $6.06/GPU/hr (median $6.79/GPU/hr across 3 providers) and the RTX A4000 starts at $0.151/GPU/hr (median $0.170/GPU/hr across 2 providers). The RTX A4000 is the cheaper of the two at the entry rate, by 98%.

What is the difference between the B200 and the RTX A4000?

The B200 has 180 GB of VRAM against the RTX A4000's 16 GB; the B200 is a Blackwell part and the RTX A4000 is Ampere (compute capability 10.0 vs 8.6); only the B200 supports FP8 compute. On price, the B200 lists from $6.06/GPU/hr and the RTX A4000 from $0.151/GPU/hr.

Which cloud providers offer the B200 and the RTX A4000?

3 providers list the B200 (HyperStack, RunPod and Vast.ai) and 2 list the RTX A4000 (HyperStack and RunPod), across 3 and 2 regions respectively. Both are available from HyperStack and RunPod.

How much does 1,000 GPU-hours cost on the B200 vs the RTX A4000?

At the lowest rates listed today, 1,000 GPU-hours costs $6,060 on the B200 and $152 on the RTX A4000, a difference of $5,909 for the same runtime. Rates are per GPU per hour and update hourly.

How this comparison is calculated

Every price is normalized to a per-GPU hourly rate using the same pipeline as every other pricing surface on Aquanode, and only the cheapest qualifying offer per provider is shown. A dash means that provider does not currently list that GPU.

Architecture, compute capability and supported precisions come from each vendor's published datasheet for that generation, not from the marketplace feed. This page regenerates at most once per hour.
