●From the file◐Predictedwhat 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.

Questions people ask

What AI models can a Radeon Pro W7800 run?
1995 of 2118 indexed open-weight models fit a Radeon Pro W7800 at 65,536 context with q4_0 KV cache, the largest being Qwen3-Next-80B-A3B-Thinking at Q2_K. That covers text, vision-language, image, video and speech models.
How much usable memory does a Radeon Pro W7800 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 W7800 fast for local AI?
Its memory bandwidth is 576 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.
