With the update of the MacBook Pro models this week, Apple has extended the M5 chip family with the introduction of the Pro and Max. At this time only the MacBook Pro 14 & 16-inch models can be optioned with the new variants. The Mac Studio has yet to be updated and can be specced with either the M4 Pro or M3 Ultra. The Mac Mini can be ordered with the vanilla M4 or M4 Pro SoC, and the iMac continues to be available only with the base M4 chip. The Mac Pro remains unchanged as well.
Illustrating the importance that Apple places on the MacBook Pro lineup, and with portables in general, Apple describes the Pro and Max chips as "the world's most advanced chips for pro laptops".
This week's chip and product updates also retroactively redefine the chip architecture for the M5 family. Whereas the previous chips, including the M5 which was only available in the MacBook Pro 14-inch until this week, had performance and efficiency cores, the performance cores are now called the super cores, the new performance cores are exclusive to the Pro and Max chips, and the efficiency cores are remain on the base M5 chip. There are three core types now: Super, Performance and Efficiency. The mix of cores has changed and the new architecture appears to hint at no more binned chips.
