Starting today, Photoshop runs natively on Macs powered by the M1 chip and takes advantage of the performance improvements built into this new architecture. Our internal tests show a wide range of features running an average of 1.5X the speed of similarly configured previous generation systems. Our tests covered a broad scope of activities, including opening and saving files, running filters, and compute-heavy operations like Content-Aware Fill and Select Subject, which all feel noticeably faster. Our early benchmarking also shows that some operations are substantially faster with the new chip.
Adobe says there were still a few features they didn't finish porting to run on the new M1, primarily new ones like Invite to Edit Cloud Documents and Preset Syncing. However, the company says performance gains across the rest of the application were so great they didn't want to hold back the release for everyone while working on the last few features. Users can always switch back to Rosetta 2 if they need to use any of them.
