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 Flan UL2?โ–ถ

Yes. At Q4 it generates ~119.8-142.8 tok/s and fits up to 65k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~2.7-3.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 65k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
