Apple announced the new M2 MacBook Pro earlier in June with the same design as the M1 variant. While there are no new design variations, the M2 chip brings the required performance upgrades to the table. However, the base model is still slower than the M1 MacBook Pro due to the single NAND flash storage chip. According to the new M2 MacBook Pro teardown by iFixit, Apple has simply recycled the old hardware and added a new chip. Scroll down to read more details on the subject.

iFixit's latest teardown reveals the insides of the new M2 MacBook Pro which can be compared to the last generation's M1 MacBook Pro. To sum it all up, Apple has not changed anything on the inside except the processor. Apple reused the body of the M1 MacBook Air since both models are identical in terms of design. Furthermore, iFixit noted that even the bottom cover of the new M2 MacBook Pro is the same as the version introduced in 2020. Both models share the model number "A2338" engraved on the bottom along with the same FCC ID. This means that Apple simply recycled the old hardware with a new chip on board.
