Can the AMD Radeon RX 7900 XTX run BLOOM-1B?

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

BLOOM-1B on the AMD Radeon RX 7900 XTX

QuantFits?Max contextSpeedBeyond context
FP16 yes 284k 302.4-369.6 t/s ~12.6-15.4 (slow)
Q8 yes 299k 604.8-739.2 t/s ~25.2-30.8 (slow)
Q4 yes 305k 1080-1320 t/s ~45-55 (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 BLOOM-1B?โ–ถ

Yes. At Q4 it generates ~1080-1320 tok/s and fits up to 305k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~45-55 tok/s.

How much context fits?โ–ถ

At Q4, up to about 305k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
