RTX 5090 vs RTX 6000 Ada: Specs, VRAM & Price
Short answer: choose the RTX 6000 Ada when 48 GB of VRAM is the gating requirement. Choose the RTX 5090 when 32 GB is enough for the workload and the lower hourly rate points that way.
The RTX 5090 has 32 GB of VRAM; the RTX 6000 Ada has 48 GB.
You can rent both by the hour, no purchase required. RTX 5090 from $0.613/GPU/hr; RTX 6000 Ada from $0.869/GPU/hr. The RTX 5090 is 29% cheaper at the entry rate.

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 RTX 5090 page and RTX 6000 Ada 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.
