Nemotron 3.5 Lightning 30B A3B is a 31.58B-parameter mixture-of-experts model (3B active per token). At Q4_K_M it needs about 26.0 GB of memory. The Intel Arc Pro B70 32GB has 30 GB usable, so it fits entirely in memory. Expect about 53 tokens/sec (33–73), with the first token after 0.3 s for a short prompt. This estimate is interpolated from benchmarks of similar setups.
| Quantization | File size | Memory | Generation | First token | Source |
