AMD MI300X vs V100: Specs, VRAM & Price
Short answer: choose the AMD MI300X when 192 GB of VRAM is the gating requirement. Choose the V100 when 32 GB is enough for the workload and the lower hourly rate points that way.
The AMD MI300X has 192 GB of VRAM; the V100 has 32 GB.
You can rent both by the hour, no purchase required. AMD MI300X from $3.29/GPU/hr; V100 from $0.110/GPU/hr. The V100 is 97% 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 AMD MI300X page and V100 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.
