●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 RTX A2000 run?
1173 of 2118 indexed open-weight models fit a RTX A2000 at 8,192 context with q8_0 KV cache, the largest being LFM2.5-Queen-Opus-4.7-8B-A1B at I1-Q4_K_S. That covers text, vision-language, image, video and speech models.
How much usable memory does a RTX A2000 actually have?
Its nameplate is 6 GB, but about 5.58 GiB is available to a model once driver and compositor overhead is accounted for.
Is a RTX A2000 fast for local AI?
Its memory bandwidth is 288 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.
