RTX A4500

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.

Aggregated from community-submitted runs, so the spread is wide by nature — it covers different models, resolutions, step counts and settings, not one controlled configuration. Read the middle 50% rather than the median alone. These figures are reproduced with attribution from vladmandic-sd-data-benchmark, which publishes no licence — so we display and link rather than redistribute them.

What AI models can a RTX A4500 run?

1930 of 2118 indexed open-weight models fit a RTX A4500 at 16,384 context with q8_0 KV cache, the largest being gemma-2-27b-it at Q4_K_M. That covers text, vision-language, image, video and speech models.

How much usable memory does a RTX A4500 actually have?

Its nameplate is 20 GB, but about 18.60 GiB is available to a model once driver and compositor overhead is accounted for.

Is a RTX A4500 fast for local AI?

Its memory bandwidth is 640 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.
