Max Yuryev of Max Tech tested the 13-inch MacBook Pro with the M2 chip and found it to be slower in performance than the M1 version.
The M2 MacBook Pro was slower than the M1 MacBook Pro in all but one of the tests. In a test with multiple apps open, the M1 was quicker than before, and in a test with 50 images, it was even quicker. 50 images were exported in 3 minutes and 36 seconds, while the M2 took 4 minutes and 12 seconds.
In these tests, the built-in 8GB unified memory of the MacBook Pro is being used by various processes, with the machine using the solid state disk for virtual memory. Slower system performance is a result of the virtual memory swap.
The results were the same across all of the stress tests done by Max Tech. The M2 MacBook Pro appears to have slower read and write speeds.
The performance difference is attributed to Apple's choice of storage. The M2 MacBook Pro has a single flash storage chip, while the M1 MacBook Pro has two. The M2's disappointing performance could be attributed to the fact that multiple NAND chips allow for faster speeds in parallel.
Higher capacity machines have not shown the same issue as the slower version of the MacBook Pro. Potential MacBook Pro buyers should be aware of the performance issue.
Further testing is needed to figure out why Apple chose a different chip setup for the M2 MacBook Pro. We will update this article if Apple responds to our questions.
