A100 vs RTX PRO 6000: Specs, VRAM & Price
Short answer: choose the RTX PRO 6000 when 96 GB of VRAM is the gating requirement. Choose the A100 when 80 GB is enough for the workload and the lower hourly rate points that way.
The A100 has 80 GB of VRAM; the RTX PRO 6000 has 96 GB.
You can rent both by the hour, no purchase required. A100 from $1.26/GPU/hr; RTX PRO 6000 from $1.38/GPU/hr. The A100 is 8% cheaper at the entry rate.
A100

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.
Memory bandwidth, tensor TFLOPS, NVLink/interconnect and max board power are the same verified-from-datasheet figures shown on each model's own A100 page and RTX PRO 6000 page, which link the primary vendor source for that model. A dash here means Aquanode hasn't verified that figure from a primary source yet, never a guess.
