Can the NVIDIA GeForce RTX 5090 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 5090

FP16 yes 421k 3673.7-4378.2 t/s ~82-97.7 (slow)
Q8 yes 424k 7347.3-8756.4 t/s ~164-195.5 (slow)
Q4 yes 425k 13120.2-15636.4 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 5090 run OpenPhenom-S/16?โ–ถ

Yes. At Q4 it generates ~13120.2-15636.4 tok/s and fits up to 425k 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 425k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
