Can the NVIDIA H100 SXM5 80GB run Unified-IO (XL)?

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

Unified-IO (XL) on the NVIDIA H100 SXM5 80GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 1011k 418-498.2 t/s ~5-5.9 (slow)
Q8 yes 1056k 836.1-996.4 t/s ~10-11.9 (slow)
Q4 yes 1075k 1493-1779.3 t/s ~17.8-21.2 (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 H100 SXM5 80GB run Unified-IO (XL)?โ–ถ

Yes. At Q4 it generates ~1493-1779.3 tok/s and fits up to 1075k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~17.8-21.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1075k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
