TESTED: Apple Mac Studio M1 Ultra: diglloyd Photoshop Benchmarks
Consult with Lloyd on your computer or photographic purchase, backup strategy, archival and storage strategy, etc.
A big thank-you to B&H Photo for sending the $7999 Apple Mac Studio M1 Ultra 20-core CPU / 64-core GPU/ 128GB / 8TB SSD for review. This is exactly the configuration I would buy excepting a preference for a 4TB SSD (only to keep the cost down).
TESTED
See the test notes for details on hardware configuration and software versions.
Inexplicably slow results from the Mac Studio M1 Ultra, coming in 26% slower than the 2021 MacBook Pro M1 Max as tested in early 2022. It seems that Adobe has gone backwards on Photoshop performance, at least in ordinary operations.
