Can the NVIDIA GeForce RTX 4080 run Very Deep VAEs (ImageNet-64)?

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

Very Deep VAEs (ImageNet-64) on the NVIDIA GeForce RTX 4080

FP16 yes 198k 2149.1-2561.3 t/s ~116.8-139.2 (slow)
Q8 yes 200k 4298.2-5122.6 t/s ~233.6-278.4 (slow)
Q4 yes 201k 7675.4-9147.4 t/s ~417.1-497.1 (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 4080 run Very Deep VAEs (ImageNet-64)?โ–ถ

Yes. At Q4 it generates ~7675.4-9147.4 tok/s and fits up to 201k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~417.1-497.1 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.
