Can the AMD Radeon RX 7900 XT run Infinity?

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

Infinity on the AMD Radeon RX 7900 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 197k 126-154 t/s ~6.3-7.7 (slow)
Q8 yes 227k 252-308 t/s ~12.6-15.4 (slow)
Q4 yes 241k 450-550 t/s ~22.5-27.5 (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.

FAQ

Can the AMD Radeon RX 7900 XT run Infinity?โ–ถ

Yes. At Q4 it generates ~450-550 tok/s and fits up to 241k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~22.5-27.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 241k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
