NVIDIA RTX 4070 vs NVIDIA RTX 4070 Super for local LLMs
9 reports on the NVIDIA RTX 4070 and 2 on the NVIDIA RTX 4070 Super
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 (504 GB/s on the NVIDIA RTX 4070, 504 on the NVIDIA RTX 4070 Super). The estimates below compare them on the models people run most.
