Can the NVIDIA GeForce RTX 4080 run BigGAN-deep 512x512?

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

BigGAN-deep 512x512 on the NVIDIA GeForce RTX 4080

QuantFits?Max contextSpeedBeyond context
FP16 yes 198k 2383.8-2840.9 t/s ~129.6-154.4 (slow)
Q8 yes 200k 4767.6-5681.9 t/s ~259.1-308.8 (slow)
Q4 yes 201k 8513.5-10146.2 t/s ~462.7-551.4 (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 4080 run BigGAN-deep 512x512?โ–ถ

Yes. At Q4 it generates ~8513.5-10146.2 tok/s and fits up to 201k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~462.7-551.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 201k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
