Apple outdid itself with the M4 MacBook Pro. Now, a top insider revealed yet another major change that no one knew about until now.

The newest M4 chips are twice as fast as those inside Macs shipped just three years ago, highlighting the power of Apple silicon.

The M4's single-core performance is between 14 and 21 percent faster than the M3s in our tests, and tests that use all the CPU cores are usually 20 or 30 percent faster. The GPU is occasionally as much as 33 percent faster than the M3 in our tests, though more often, the improvements are in the single or low double digits.

With the MacBook Pro 14-inch M4, Apple has created a pro-grade portable that impresses in every respect. It joins Apple's pantheon of outstanding laptops, and is set to take a well-deserved place at or near the top of our best laptops rankings.

Young took to X on Thursday to point out that Apple has adopted a "quantum dot" display for the M4 MacBook Pro. The hardcore technical details are that Apple replaced the red KSF phosphor film it had used on previous MacBook displays with quantum dot film.

I recently mused about how the Mac lineup has been the most compelling for a while, and one of the reasons is that Apple introduced worthwhile features besides the chip upgrade to the M4. For the M4 MacBook Pro,

M4 MacBook Pro reviews mostly endorsed my own view that, while the machine would make a great purchase for Intel MBP owners, there isn’t a compelling reason for any M-series user to upgrade. However,

As I wrote in my review, my MacBook Pro M4 is a performance beast that I use hours a day. And it has a benefit I didn’t even realize. In an X post display analyst Ross Young says Apple used a quantum dot film instead of a red KSF phosphor film in the laptop.
