Frequently asked questions

What is the best GPU for local LLMs under $400?

The Intel Arc A770 16GB (16 GB, $349 at launch). It runs 28 of the 69 models we track at Q4_K_M or better, up to gpt-oss 20B.

Does VRAM or speed matter more?

VRAM first: it decides which models fit at all. Memory bandwidth then sets how many tokens per second you get. A slower card with more VRAM usually beats a faster card that cannot fit the model.

Is a used RTX 3090 worth it?

For local AI it often is: 24 GB of VRAM and high bandwidth for well under its launch price on the used market. Check the seller, the card's condition and that your power supply can handle it.
