If you peruse the initial evaluations of Apple's latest Macs powered by the M3 chip, you might get the impression that not much has altered within their CPU cores, aside from some number tweaks and an increase in the peak frequency of their P cores. With my early arrival of the MacBook Pro 16-inch M3 Max, this article offers an initial assessment of the modifications within their CPU cores and how these changes may influence your selection of the right chip for your next Apple silicon Mac. In line with Apple's approach, I will draw comparisons between the M1 and M3 chips, as, in most of the aspects discussed here, the M2 CPU cores did not undergo as significant a transformation from those found in the M1, and I have had the opportunity to test four different M1 models.
