Can the AMD Radeon RX 7900 XT run Kosmos-2?

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

Kosmos-2 on the AMD Radeon RX 7900 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 209k 157.5-192.5 t/s ~7.9-9.6 (slow)
Q8 yes 233k 315-385 t/s ~15.8-19.3 (slow)
Q4 yes 244k 562.5-687.5 t/s ~28.1-34.4 (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 AMD Radeon RX 7900 XT run Kosmos-2?โ–ถ

Yes. At Q4 it generates ~562.5-687.5 tok/s and fits up to 244k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~28.1-34.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 244k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
