Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.

FAQ

Can the NVIDIA GeForce RTX 4080 run Gemma 3 QAT 12B?โ–ถ

Yes. At Q4 it generates ~80-95.3 tok/s and fits up to 40k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~4.3-5.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 40k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
