Radeon AI PRO R9700 workstation (32 GB) vs RTX 5090 workstation (1x 32 GB)
Radeon AI PRO R9700 workstation (32 GB) · RTX 5090 workstation (1x 32 GB)
Verdict
- throughputThe RTX 5090 workstation (1x 32 GB) delivers approximately 103% higher aggregate decode throughput across the 8 models both machines can run (geometric mean of the per-model ratios).
- capacityBoth machines run all 8 compared models, so this is a pure speed and cost decision rather than a capability one.
- costAt 8 hours a day, the Radeon AI PRO R9700 workstation (32 GB) has approximately 25% lower total monthly cost (€34 against €46), for a C corporation in United States (federal).
- powerThe RTX 5090 workstation (1x 32 GB) draws 640 W under load against 420 W for the Radeon AI PRO R9700 workstation (32 GB) — a 1.5× difference that shows up in the electricity line and in how loud and hot the room gets.
- evidence2 of 8 model rows have at least one real measurement behind them; the rest are estimated from memory bandwidth. Margins below roughly 20% should not decide a purchase.
- recommendationThere is no single answer: the RTX 5090 workstation (1x 32 GB) is faster, the Radeon AI PRO R9700 workstation (32 GB) is cheaper to own, and the RTX 5090 workstation (1x 32 GB) gives more throughput per euro of purchase price. Pick on whichever constraint actually binds you — interactive latency, monthly budget, or capacity headroom for larger models later.

Differences under 10% are reported as a tie: they are smaller than the spread between published benchmarks of the same configuration, so calling a winner would be false precision. Rows where a model fits on only one machine are decided by capacity, not speed.
