RTX A4500 vs T4: Specs, VRAM & Price
Short answer: choose the RTX A4500 when 20 GB of VRAM is the gating requirement. Choose the T4 when 16 GB is enough for the workload and the lower hourly rate points that way.
The RTX A4500 has 20 GB of VRAM; the T4 has 16 GB.
You can rent both by the hour, no purchase required. RTX A4500 from $0.209/GPU/hr; T4 from $0.185/GPU/hr. The T4 is 12% 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 A4500 page and T4 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.
