Or not. There is no reason to believe Apple design has not been a major contribution to the performance. Sure TSMC process is a major component but to quote yourself it does not follow that that explains all of it. It could very well be that a hypothetical Apple design to Intel fab would still run circles around current Intel chips (or not). What we do know is system architecture is sufficiently different, and that it is likely to have a material impact on performance.
That’s just not true. The RISC instruction set has a growing advantage in performance per watt. There’s a reason no one is producing low-power x86 chips.
Surely it's a shrinking advantage? x86 CPUs have been microcode based for a long time, and the hardware to convert x86 instructions to micro ops is a relatively fixed cost that diminishes over time with process shrinks?
Are you implying that's not something to be impressed about just because lithography is not a property of the architecture?
