Can the AMD Radeon RX 7800 XT run LLaMA-7B?

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

LLaMA-7B on the AMD Radeon RX 7800 XT

Q8 yes 50k 58.7-71.7 t/s ~3.8-4.6 (slow)
Q4 yes 72k 104.8-128.1 t/s ~6.7-8.2 (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 7800 XT run LLaMA-7B?โ–ถ

Yes. At Q4 it generates ~104.8-128.1 tok/s and fits up to 72k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~6.7-8.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 72k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
