How this list is built

Each row is the lowest-perplexity-loss quant of that model whose estimated total — weights plus KV cache at 4K context plus activation buffer — uses at most 88% of the card. That is the calculator's "green" threshold, so every row here has real headroom rather than only just fitting. Raise the context length and the list shortens; the calculator lets you check any combination directly.

Stepping up

A RTX 4080 Super (16GB) fits 6 more of the indexed models than this card. RTX 4080 Super

45 of 79 indexed models fit comfortably in 12GB at 4K context, each at the highest-quality quant that still leaves headroom.
