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.
Measured on this card
| Workload◍ | Median | Middle 50% | Runs |
|---|---|---|---|
| Image generation | 8.00 it/s | 7.45–8.74 | 12 |
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 Pro W6800 run?
- 2022 of 2118 indexed open-weight models fit a Radeon Pro W6800 at 4,096 context with f16 KV cache, the largest being Hypernova-60B-2605 at I1-Q3_K_S. That covers text, vision-language, image, video and speech models.
- How much usable memory does a Radeon Pro W6800 actually have?
- Its nameplate is 32 GB, but about 29.76 GiB is available to a model once driver and compositor overhead is accounted for.
- Is a Radeon Pro W6800 fast for local AI?
- Its memory bandwidth is 512 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.
