NVIDIA RTX 5070 Ti vs NVIDIA RTX Pro 4500 Blackwell 32GB for local LLMs
51 reports on the NVIDIA RTX 5070 Ti and 5 on the NVIDIA RTX Pro 4500 Blackwell 32GB
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 (896 GB/s on the NVIDIA RTX 5070 Ti, 896 on the NVIDIA RTX Pro 4500 Blackwell 32GB).
