Affinity photo is a photoshop alternative. It is supposed to be quite good, and is exactly the type of workload I would expect to see running on a MacBook Pro. It’s only indicative of the performance of that one workload, but that is still quite useful IMO.
As for a Linux user that's probably not of big use for me. But it would be great to have more professional graphics tools with Linux support for sure.
I can't remember the last time I had to wait for affinity or Photoshop to compute. Maybe if you have 100MP images from a Hasselblad?
