The M4 represents as much of a philosophical shift as it does a performance upgrade. It is Apple acknowledging that if you’re buying a laptop with “Pro” in the name, than it should be a better machine.

The biggest reason to upgrade to the MacBook Pro M4 is the performance. This machine gets the newest M4 chip that is based on a 3-nanometer process, promising the fastest CPU core and better multithreaded performance than M3. Based on our testing, the M4 blows a lot of the competition away but not on every test.

I tested a beautiful Space Black MacBook Pro with the new M4 Pro chip and 48GB memory (which I would treasure if it belonged to me). The 3-nanometer chip it uses has 14 cores, consisting of 10 performance and four efficiency cores; it has a 2TB drive; a Liquid Retina XDR nanotexture display; and it costs $3,349.
