Mark Gurman, a journalist for Bloomberg, recently learned that Apple is already developing new 14" and 16" MacBook Pro models featuring M2 Pro and M2 Max processors. His sources indicate that the upgraded 14-inch and 16-inch Pros could go on sale as soon as this fall.
The enhanced performance of the base M2 will be carried over to the upcoming M2 Pro and M2 Max processors, which will probably also add more cores. Gurman claims that the M2 Pro and M2 Max will concentrate on the graphics side. In particular if you choose the 10-core GPU version, the M2 in the 13-inch MacBook Pro and new MacBook Air demonstrated approximately 11% better single-core performance, nearly 20% better multi-core results, and as much as 35% better graphics scores.
Gurman doesn't anticipate major changes to the MacBook Pro's other components. Recent 14-inch and 16-inch Pro models, which are less than a year old, introduced significant improvements such a redesigned design, mini-LED displays, and MagSafe charging.
Apple might aim for a Fall unveiling of the new MacBook Pro 14 and 16, but due to processor constraints, it might have to push back the launch date until spring 2023.
