●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 Arc A770M 16GB run?
1416 of 2118 indexed open-weight models fit a Arc A770M 16GB at 65,536 context with f16 KV cache, the largest being Qwen3.5-21B-Claude-4.6-Opus-Deckard-Heretic-Uncensored-Thinking at IQ4_XS. That covers text, vision-language, image, video and speech models.
How much usable memory does a Arc A770M 16GB 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 Arc A770M 16GB 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.
