Can the NVIDIA GeForce RTX 5090 run Hybrid H3-355M?

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

Hybrid H3-355M on the NVIDIA GeForce RTX 5090

QuantFits?Max contextSpeedBeyond context
FP16 yes 415k 1842.5-2195.8 t/s ~41.1-49 (slow)
Q8 yes 421k 3685-4391.7 t/s ~82.3-98 (slow)
Q4 yes 423k 6580.3-7842.3 t/s ~146.9-175.1 (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 Hybrid H3-355M?โ–ถ

Yes. At Q4 it generates ~6580.3-7842.3 tok/s and fits up to 423k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~146.9-175.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 423k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
