This work is not free; it is very time consuming with no direct reward. I need your support. Thank you for buying your Macs and other gear at B&H Photo, which provided the machine for testing. Subscribing to my photographic publications is another way to help support work like this—consider that AppleCare alone is $350 on $4000 to $7000 machine.
Consult with Lloyd to design a complete system for photography or similar including backup and data safety.
But now that I purchased a deeply discounted MBP M1 Max, I was able to go back and run the tests for comparison.
The results should inform anyone considering the up to $1900 discount vs the current M2 Max model. The M2 Max is notably faster (typically 20%), but the pricing is about 30% higher than the M1 Max model.
