// RUN โ€” FITS

Can the AMD Radeon RX 7900 XTX run base LM+GNN+kNN?

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

base LM+GNN+kNN on the AMD Radeon RX 7900 XTX

QuantFits?Max contextSpeedBeyond context
FP16 yes 306k 1103.6-1348.9 t/s ~46-56.2 (slow)
Q8 yes 310k 2207.3-2697.8 t/s ~92-112.4 (slow)
Q4 yes 312k 3941.6-4817.5 t/s ~164.2-200.7 (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 base LM+GNN+kNN?โ–ถ

Yes. At Q4 it generates ~3941.6-4817.5 tok/s and fits up to 312k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~164.2-200.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 312k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
