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 WizardCoder-15.5B?โ–ถ

Yes. At Q4 it generates ~150.7-179.6 tok/s and fits up to 73k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~3.4-4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 73k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
