Apple has finally unveiled core technologies in its M5 Pro and M5 Max chips. On March 20, IT outlet NineToFiveMac reported that Apple disclosed why it moved away from a two-type core structure focused on efficiency and performance and introduced a three-type structure in the M5 chip, adding efficiency, performance and super cores.

The existing M5 chip consists of efficiency cores and super cores, but performance cores have been newly added to the M5 Pro and M5 Max. Super cores are Apple’s most powerful CPU cores. They maximise efficiency by applying higher clock speeds than existing performance cores and a custom microarchitecture. Anand Shimpi (아난드 심피), who is in charge of Apple hardware technology, stressed, "A super core is not simply a fast core. We maximised efficiency through a custom design."

Performance cores handle multi-threaded tasks and serve to balance efficiency and performance. Doug Brooks (더그 브룩스), an Apple Mac product manager, explained, "The three-type core structure is meant to clearly express the performance characteristics of each." Asked about the possibility that the fusion architecture of the M5 Pro and M5 Max chips could be applied to a future M5 Ultra chip, Shimpi said, "At present, only the M5 Pro and Max have been announced," avoiding specific comment.

But the industry expects that if an M5 Ultra chip appears, the combination of super cores and performance cores will become more powerful. The new M5 MacBook Pro and MacBook Air have already been released, and attention is on what changes Apple’s core strategy will bring to the future Mac lineup.
