Did you actually see benefits with your workloads? Or not really?
Yes.
M1 Pro is twice as fast as M1 at exporting photos in Capture One Pro to me. Navigating, scrolling my larger collections, and making edits are much faster as well.
Also it's a lot faster for compiling code.
Also it runs Fusion 360 with ease.
Also I can actually play StarCraft 2 at 4K all medium settings without framerate taking a nose dive.
Also I can run REW with more than 10 data points now without the whole thing slowing to a crawl.
Best of all, I have been able to do all of the above in Low Power Mode and they are still faster than the M1 MacBook Pro 13".
I was getting 15-16 hours of use out of the 13" Pro. Now I'm getting 12-14 hours with the 14". Honestly, not that big of a loss.
