Can the NVIDIA GeForce RTX 5090 run CPM-Ant?

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

CPM-Ant on the NVIDIA GeForce RTX 5090

QuantFits?Max contextSpeedBeyond context
FP16 yes 48k 65.4-78 t/s ~1.5-1.7 (slow)
Q8 yes 109k 130.8-155.9 t/s ~2.9-3.5 (slow)
Q4 yes 136k 233.6-278.4 t/s ~5.2-6.2 (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 CPM-Ant?โ–ถ

Yes. At Q4 it generates ~233.6-278.4 tok/s and fits up to 136k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~5.2-6.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 136k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
