AMD RX 9070 XT now faster than RTX 5070 Ti with 9% gain at 1440p since launch

Another YTer couldn't confirm those performance gains - https://www.youtube.com/watch?v=hf1q1nwoj8k

Ok, but these comparisons seem to be geared towards gaming, ... how do these cards compare in terms of machine learning with pytorch/libtorch and such? Say if I'm trying to train an LSTM/Conv model, or maybe even a small llama?
