That would be great if that was the case. However you were probably mislead by the title - that IPC increase applies only to 9XXX beasts (Zen 5), not these two AM4 refreshes. At least that's how I understand it.
If the new chips were actually faster than than current line. i.e. Ryzen 9 5950X has higher frequencies and Ryzen 7 5800XT increases boost only by 0.1GHz over Ryzen 7 5800X while Ryzen 9 5900X has more cores and same boost clock.
I hardly see anybody upgrading due to 0.1GHz, I'm curious though, what is your rationale? Perhaps you have a slower CPU and you would upgrade since the prices came down?
I'm not sure that serious ML doesn't need a huge graphics card.
