alt Hacker NewsYes, they both have the same and Intel cores are known to be bigger than AMD and Apple cores but poor in area/performance.
So I'm not sure what your original post about smaller cores is all about considering that the A18 Pro CPU is almost certainly smaller in actual die size.
It's not about die area at all. It's about the SSD and chipset and WiFi etc. each using power on top of what the CPU uses, and ending up as a much larger percentage of system power draw for a 15W CPU than for the same system with a 60W CPU that has around four times the multi-thread performance by having four times as many of the exact same cores.
