Radeon RX 9070 XT

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.

What AI models can a Radeon RX 9070 XT run?

854 of 2118 indexed open-weight models fit a Radeon RX 9070 XT at 131,072 context with f16 KV cache, the largest being Kimi-Linear-48B-A3B-Instruct at IQ1_M. That covers text, vision-language, image, video and speech models.

How much usable memory does a Radeon RX 9070 XT 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 XT 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.
