RTX 5090 vs RTX 4090

Signed, community-submitted decode tok/s, prefill, and TTFT for RTX 5090 vs RTX 4090 — every number links to the run it came from.

Verdict

RTX 5090 and RTX 4090 both have submitted runs, but no single model has been measured on both yet — so there is no apples-to-apples row. Each side's measured decode tok/s is listed separately below (peaks of 356 and 195 tok/s). Submit a shared workload to turn this into a direct comparison.
