●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?
2039 of 2118 indexed open-weight models fit a Radeon Pro W7800 at 16,384 context with q4_0 KV cache, the largest being MiniMax-M2.1-REAP-139B-A10B at I1-IQ2_M. That covers text, vision-language, image, video and speech models.
How much usable memory does a Radeon Pro W7800 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 Radeon Pro W7800 fast for local AI?
Its memory bandwidth is 864 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.
