Apple's large cores are quite remarkable. One of Apple's goals in recent years has been to try to control every last component that goes into their products, and I still think they planned their big core uArch from the beginning to give themselves some legroom in case they wanted a very high performance iPad (which they got) or to transition their Mac code base (as they've done before) to ARM so they wouldn't have to pay Intel their ridiculous ~60% x86 margins. Their audience is captive due to their closed platform; MacOS and iOS have never been about compatibility at all cost but rather an exceptionally good experience within the limited scope of their ecosystem, and their (very adult) management has always been about maximizing gross margins.

It's notable that the current draw on their their big cores have forced them to throttle clock speeds in as little as a year to preserve battery longevity including 2017 models. I still think their extremely robust big cores weren't necessarily designed with exclusive mobile usage in mind first and foremost, but were meant to dazzle in the short term with excellent benchmark numbers for launches and also to provide some head room for future iPads and Macs. It is my impression the IPC gains were fairly modest year over year since the A7 when they first introduced the 6 wide design, and much of the gains were from substantially ramped clockspeeds 1.3 ghz in A7 to 2.5 ghz in a12 and the vastly improved memory subsystem.

It is ironic that Windows on Arm which would require such a beefy core is forced to use inferior ARM designs despite having the software stack to fully emulate x86, whereas Apple has yet to move MacOS to their own hardware. I would definitely buy an ARM Macbook provided they let me boot Linux or Windows on ARM there if I wanted, though ARM is finally realizing that the pizzazz of benchmarks do matter to their customers and that they could have clout in the data center if they tried. They will soon mainstream the A76 and its two successors that will have it scraping very close to Apple's big core performance.
