I would estimate the overall performance as:

MacBook Pro M1 Max 32GB: 100%
ThinkPad X9-15p Aura: 90–105%, depending on the workload.

The biggest difference is price:

MacBook Pro: €1279 with 2 year warranty!
ThinkPad: €2500

For nearly half the price, the M1 Max delivers equal or better performance in most of the creative applications I use. With our European Tv Radio station we can proof that! I question the independence of notebookcheck, the rating should be something like 80%.  the M1 Max offers substantially better value for professional creatives and their workflow. Why this bullshit all the time about NPU's, they have been in CPU's for 10 years now, the newer ones  are more efficient, thats true, but will only save you about 20 euros a year! I would like to see more critical reviews by notebookcheck, because this is marketing bullshit! You must not bite your master's hand.
