M4 Max 128GB vs NVIDIA RTX 3060 12GB for local LLMs
53 reports on the M4 Max 128GB and 68 on the NVIDIA RTX 3060 12GB
Which is faster for local LLMs?
Nobody has reported the same model at the same quant on both cards yet, so there's no measured head-to-head. Memory bandwidth, which caps how fast a card can write, is 1.5x higher on the M4 Max 128GB (546 GB/s on the M4 Max 128GB, 360 on the NVIDIA RTX 3060 12GB). The estimates below compare them on the models people run most.
