Not everyones a developer. M1 vs M3 performance boost for video editing seems like a decent upgrade. I'm still on M1 and I spent £4k+ on specced up MBP 14 inch. Its not struggling but it doesn't perform well when editing 4k with one layer of effects in DaVinci.
I was wondering about the improvement for photo and video editing, but that would be more of a function of the GPU than the CPU, wouldn't it? I certainly need more than 8GB of RAM for photo editing... memory pressure slows down Photoshop and Lightroom.
I just took delivery of a new-in-the-box MacBook Pro M1 Max with 64 GB RAM (cyber Monday deal)... hopefully Lightroom Classic is much faster with this hardware!
