Can the NVIDIA A100 SXM4 80GB run SPHINX (Llama 2 13B)?

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

SPHINX (Llama 2 13B) on the NVIDIA A100 SXM4 80GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 123k 37.4-44.6 t/s ~0.7-0.9 (slow)
Q8 yes 199k 74.8-89.1 t/s ~1.5-1.7 (slow)
Q4 yes 233k 133.6-159.2 t/s ~2.6-3.1 (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 A100 SXM4 80GB run SPHINX (Llama 2 13B)?โ–ถ

Yes. At Q4 it generates ~133.6-159.2 tok/s and fits up to 233k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~2.6-3.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 233k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
