Can the NVIDIA GeForce RTX 3090 Ti run minChatGPT?

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

minChatGPT on the NVIDIA GeForce RTX 3090 Ti

QuantFits?Max contextSpeedBeyond context
FP16 yes 264k 224.5-267.5 t/s ~8.9-10.6 (slow)
Q8 yes 289k 449-535.1 t/s ~17.8-21.2 (slow)
Q4 yes 300k 801.7-955.5 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 3090 Ti run minChatGPT?โ–ถ

Yes. At Q4 it generates ~801.7-955.5 tok/s and fits up to 300k 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 300k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
