Can the NVIDIA GeForce RTX 4080 run minChatGPT?

Yes โ€” here's how fast and up to what context, with real measured numbers.

minChatGPT on the NVIDIA GeForce RTX 4080

QuantFits?Max contextSpeedBeyond context
FP16 yes 152k 163.9-195.3 t/s ~8.9-10.6 (slow)
Q8 yes 177k 327.8-390.7 t/s ~17.8-21.2 (slow)
Q4 yes 188k 585.4-697.6 t/s ~31.8-37.9 (slow)

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 minChatGPT?โ–ถ

Yes. At Q4 it generates ~585.4-697.6 tok/s and fits up to 188k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~31.8-37.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 188k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
