Can the NVIDIA GeForce RTX 5090 run ProtGPT2?

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

ProtGPT2 on the NVIDIA GeForce RTX 5090

QuantFits?Max contextSpeedBeyond context
FP16 yes 404k 886.3-1056.3 t/s ~19.8-23.6 (slow)
Q8 yes 415k 1772.6-2112.5 t/s ~39.6-47.2 (slow)
Q4 yes 420k 3165.3-3772.4 t/s ~70.7-84.2 (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 5090 run ProtGPT2?โ–ถ

Yes. At Q4 it generates ~3165.3-3772.4 tok/s and fits up to 420k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~70.7-84.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 420k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
