AMD RX 9070 XT 16GB vs NVIDIA V100 32GB for local LLMs
21 reports on the AMD RX 9070 XT 16GB and 28 on the NVIDIA V100 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 41% higher on the NVIDIA V100 32GB (640 GB/s on the AMD RX 9070 XT 16GB, 900 on the NVIDIA V100 32GB).
