●From the file◐Predictedwhat these mean

Speed is modeled, not measured: decode is memory-bandwidth bound, so tokens per second is bytes read per token against achievable bandwidth. Mixture-of-experts models carry a wider band because only the routed experts are read each step, and few have been measured publicly.

Aggregated from community-submitted runs, so the spread is wide by nature — it covers different models, resolutions, step counts and settings, not one controlled configuration. Read the middle 50% rather than the median alone. These figures are reproduced with attribution from vladmandic-sd-data-benchmark, which publishes no licence — so we display and link rather than redistribute them.

Questions people ask

What AI models can a GeForce RTX 3090 Ti run?
1950 of 2118 indexed open-weight models fit a GeForce RTX 3090 Ti at 16,384 context with f16 KV cache, the largest being OpenBuddy-R1-0528-Distill-Qwen3-32B-Preview0-QAT at Q4_0. That covers text, vision-language, image, video and speech models.
How much usable memory does a GeForce RTX 3090 Ti actually have?
Its nameplate is 24 GB, but about 22.32 GiB is available to a model once driver and compositor overhead is accounted for.
Is a GeForce RTX 3090 Ti fast for local AI?
Its memory bandwidth is 1008 GB/s, and that figure — not teraflops — is what governs token generation speed. Capacity decides what you can run; bandwidth decides how fast it runs.
