WWDC 2022 saw the announcement of Apple's new 13-inch MacBook Pro (2022), which comes with the new M2 chipset. The M2 chip model is a step up from the previous generation. 

Two YouTubers (Created Tech and Max Tech) have submitted videos in which they claim that refreshed models are not an upgrade, but rather a slight increase in performance. 

A 256GB SSD and 8GB of RAM power the new M2 chipset. In contrast, as seen in the videos, the read and write data speeds are significantly slower than before.

In addition to opening the laptops' backs, the YouTubers also examined the motherboards. Apple has claimed the new M2 chipset is a huge upgrade over the M1 chipset, but in reality, it doesn't appear to be.

In comparison with the M1 chipset, the much-hyped Apple M2 chipset debuted at the WWDC conference earlier this month is slower at reading/writing SSD data. 

Max Tech shared a video claiming that the 13-inch Apple MacBook Pro equipped with the M2 chipset has significantly slower read and write speeds when compared to its M1-based counterpart. 

The Blackmagicdesign Disk Speed Test program has been used to test the speed of the 256GB SSDs on both laptops.

According to test results, I2's SSD write speed is 2,215MB/s, while M1's is 1,463MB/s. The M2 chip has a Read speed of 1,446MB/s compared to the staggering 2,900MB/s of the M1 chip.

Similar results were also shared by another YouTuber, Created Tech. In response to the results of the test, the YouTubers sought to determine why the M2 chipset's SSD reading and writing speeds are slower. 

The laptops' rear panels have been opened to compare their insides. Their findings found the MacBook Pro 2022 with the M2 chip has only one NAND flash storage chipset, compared to the previous generation model which had two.

A NAND flash storage chip acts as a highway for users' data, so it can read and write more quickly. Speeds are dropping because of this. A NAND storage may not have been used by Apple.
