Can the NVIDIA A100 SXM4 80GB run GPT-J-6B?

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

GPT-J-6B on the NVIDIA A100 SXM4 80GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 458k 122.9-146.5 t/s ~2.4-2.9 (slow)
Q8 yes 504k 245.9-293 t/s ~4.8-5.7 (slow)
Q4 yes 524k 439.1-523.3 t/s ~8.6-10.3 (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 GPT-J-6B?โ–ถ

Yes. At Q4 it generates ~439.1-523.3 tok/s and fits up to 524k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~8.6-10.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 524k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
