From the filePredictedwhat 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.

Questions people ask

What AI models can a Radeon RX 9070 run?
1856 of 2118 indexed open-weight models fit a Radeon RX 9070 at 4,096 context with f16 KV cache, the largest being Gemma4-Gutenberg-31B at IQ3_XXS. That covers text, vision-language, image, video and speech models.
How much usable memory does a Radeon RX 9070 actually have?
Its nameplate is 16 GB, but about 14.88 GiB is available to a model once driver and compositor overhead is accounted for.
Is a Radeon RX 9070 fast for local AI?
Its memory bandwidth is 640 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.
