Apple launched the new 13-inch M2 MacBook Pro at the WWDC 2022 event. Starting at $1,299, the new notebook can be configured up to 16GB unified memory, and up to 2TB storage. Although the new 13-inch M2 MacBook Pro is powered by advanced M2 processor, it has slower SSD read/write speeds than the 2020 to the equivalent previous-generation model.
The M2 chip features 8-core CPU and up to 10-cores GPU which is two more than M1 chip. According to Apple, 13-inch MacBook Pro is almost 40% faster than the previous model and put to 3.4x faster from Intel-based models. Furthermore, the M2 MacBook Pro supports up to 24GB of fast unifed memory with 50% more memory bandwidth.
The 256GB M2 MacBook Pro model has slower SSD read and write speeds than the 256GB M1 MacBook Pro
YouTubers, Created Tech, and Max Tech ran Blackmagic’s Disk Speed Test on a 13-inch M2 MacBook Pro with 256GB of storage and found that both SSD read and write speeds of the new notebook are slower than the 13-inch M1 MacBook Pro with 256GB of storage. @Max Tech for the following “Disk Speed Test” app numbers:
13-inch M1 MacBook Pro (256GB)
- Read Speed: 2,900
- Write Speed: 2,215
13-inch M2 MacBook Pro (256GB)
- Read Speed: 1,446
- Write Speed: 1,463
The teardown of the new MacBook Pro with M2 chip base model by @Created Tech revealed that it has a single (larger) NAND flash 256GB storage chip than its M1 predecessor which was equipped with two NAND chips, likely with 128GB each.
The YouTuber concluded that the difference can be due to several factors like global chip shortage, cost-cutting, or to push the consumers to buy upgraded models.
