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 RTX A6000 run?
1975 of 2118 indexed open-weight models fit a RTX A6000 at 131,072 context with q8_0 KV cache, the largest being Huihui-Qwen3-Coder-Next-abliterated at IQ4_NL. That covers text, vision-language, image, video and speech models.
How much usable memory does a RTX A6000 actually have?
Its nameplate is 48 GB, but about 44.64 GiB is available to a model once driver and compositor overhead is accounted for.
Is a RTX A6000 fast for local AI?
Its memory bandwidth is 768 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.
