Can the AMD Radeon RX 7900 XTX run BigGAN-deep 512x512?

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

BigGAN-deep 512x512 on the AMD Radeon RX 7900 XTX

QuantFits?Max contextSpeedBeyond context
FP16 yes 311k 2683.4-3279.7 t/s ~111.8-136.7 (slow)
Q8 yes 312k 5366.7-6559.3 t/s ~223.6-273.3 (slow)
Q4 yes 313k 9583.4-11713.1 t/s ~399.3-488 (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 AMD Radeon RX 7900 XTX run BigGAN-deep 512x512?โ–ถ

Yes. At Q4 it generates ~9583.4-11713.1 tok/s and fits up to 313k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~399.3-488 tok/s.

How much context fits?โ–ถ

At Q4, up to about 313k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
