●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 RX 7700 run?
1687 of 2118 indexed open-weight models fit a Radeon RX 7700 at 32,768 context with f16 KV cache, the largest being Qwen2.5-14B at Q4_0. That covers text, vision-language, image, video and speech models.
How much usable memory does a Radeon RX 7700 actually have?
Its nameplate is 16 GB, but about 14.88 GiB is available to a model once driver and compositor overhead is accounted for.
Is a Radeon RX 7700 fast for local AI?
Its memory bandwidth is 624 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.
