NVIDIA RTX 3070 vs NVIDIA RTX 4060 for local LLMs

3 reports on the NVIDIA RTX 3070 and 4 on the NVIDIA RTX 4060

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 1.6x higher on the NVIDIA RTX 3070 (448 GB/s on the NVIDIA RTX 3070, 272 on the NVIDIA RTX 4060). The estimates below compare them on the models people run most.
