Re: Unsurprising results
Shirley Intel, IBM and AMD also have the best people and a ton of cash??
They do (although Apple have nearly 4 times the cash of Intel, IBM and AMD combined), but they also have the baggage of x86, which is very CISC, and arguably not particularly great. AMD simply extended this when creating x64.
Arm on the other hand was initially designed by a small team based on lessons learnt from the MOS 6502, this lead to a simple and lean architecture, which (possibly due to some other work Acorn had at the time) also happened to have nice low interupt latency. The initial ARM was so power efficient it could run without power. :)
Also, when it came to the 64 bit transition, Intel dropped the ball with IA64, which left AMD to capitalise with it's 64 bit extensions to IA32. However, this still leaves the legacy of the old ISA, whereas Arm, coming to the party a lot later, were able to design a 64 bit instruction set that learnt from the lessons of others, and also removed some features that whilst useful at the time were less helpful when designing a modern out of order superscalar CPU.
Apple Silicon all built on ARM licenced technology.
It's built on an Arm licenced architecture. Apple have an architectural Arm licence, they design the CPU and GPU themselfs. (As oppose to a core licencee who uses an Arm core design with their own surrounding IP). There's speculation that they have a particularly special licence too, which considering they were one of the co-founders of Arm is not entirely unlikely.
Apple have been slowly building up to this for some time now, they bought a chip company years ago to design the (increasingly powerfull) CPU in the iThings and Arm on Mac has been one of those things that has been about to happen for years now.
