Can the NVIDIA GeForce RTX 4080 run OpenPhenom-S/16?

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

OpenPhenom-S/16 on the NVIDIA GeForce RTX 4080

QuantFits?Max contextSpeedBeyond context
FP16 yes 196k 1508.8-1798.2 t/s ~82-97.7 (slow)
Q8 yes 199k 3017.7-3596.4 t/s ~164-195.5 (slow)
Q4 yes 200k 5388.7-6422.1 t/s ~292.9-349 (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 4080 run OpenPhenom-S/16?โ–ถ

Yes. At Q4 it generates ~5388.7-6422.1 tok/s and fits up to 200k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~292.9-349 tok/s.

How much context fits?โ–ถ

At Q4, up to about 200k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
