Llama 3.1 8B is a 8.03B-parameter model. At Q4_K_M it needs about 5.7 GB of memory. The AMD Radeon AI PRO R9700 32GB has 30 GB usable, so it fits entirely in memory. Expect about 82 tokens/sec (49–115), with the first token after 0.3 s for a short prompt. This estimate is interpolated from benchmarks of similar setups.
