NVIDIA RTX 3060 12GB vs NVIDIA RTX 4000 Ada for local LLMs
50 reports on the NVIDIA RTX 3060 12GB and 0 on the NVIDIA RTX 4000 Ada
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 about the same on both (360 GB/s on the NVIDIA RTX 3060 12GB, 360 on the NVIDIA RTX 4000 Ada). The estimates below compare them on the models people run most.
