Can the AMD Radeon RX 7900 XTX run Zagreus 0.4B?

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

Zagreus 0.4B on the AMD Radeon RX 7900 XTX

QuantFits?Max contextSpeedBeyond context
FP16 yes 302k 756-924 t/s ~31.5-38.5 (slow)
Q8 yes 308k 1512-1848 t/s ~63-77 (slow)
Q4 yes 311k 2700-3300 t/s ~112.5-137.5 (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.

Can the AMD Radeon RX 7900 XTX run Zagreus 0.4B?โ–ถ

Yes. At Q4 it generates ~2700-3300 tok/s and fits up to 311k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~112.5-137.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 311k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
