MPG tested the Apple 16.2" MacBook Pro with M2 Max Chip Z1740017Z, maxed-out excepting 4TB SSD.
Ever popular Adobe Photoshop Lightroom ("Lightroom") requires that files be imported into its database before they can be worked on. Import was done with Add (don’t copy) and generate 1:1 previews in parallel, no lookup of location, etc. Time was measured until the preview-generation progress bar disappeared.
Export was high-quality level 90 JPEG at full resolution, with no extra processing involved.
Disk I/O not a factor, the files being on a fast SSD.
The M1 Max takes 49% longer than the M2 Max for Import (odd), but is the same for Export.
The 20-core Apple Mac Studio closes the gap easily outpaces the 2019 Mac Pro.
The high-end 2019 Mac Pro with its 28 CPU cores easily outpaces the other machines, but the most common Mac Pro configurations (8/10/12 cores) would be running neck-and-neck or slower than the MacBook Pro M2 Max, so the MBP deserves high praise.
Note: Lightroom on the 2019 iMac 5K exhibited erratic CPU usage and minimal GPU usage. Performance seeemingly could be better (poor CPU/GPU utilization), but Lightoom does what it does.
