M5 Max 128GB vs NVIDIA RTX 5070 Ti for local LLMs
49 reports on the M5 Max 128GB and 56 on the NVIDIA RTX 5070 Ti
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 46% higher on the NVIDIA RTX 5070 Ti (614 GB/s on the M5 Max 128GB, 896 on the NVIDIA RTX 5070 Ti).
