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 Radeon RX 6750 XT run?
- 1709 of 2118 indexed open-weight models fit a Radeon RX 6750 XT at 8,192 context with f16 KV cache, the largest being ERNIE-4.5-21B-A3B-Thinking at Q3_K_M. That covers text, vision-language, image, video and speech models.
- How much usable memory does a Radeon RX 6750 XT actually have?
- Its nameplate is 12 GB, but about 11.16 GiB is available to a model once driver and compositor overhead is accounted for.
- Is a Radeon RX 6750 XT fast for local AI?
- Its memory bandwidth is 432 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.
