Apple Silicon: The Passing of Wintel

No, it's also about system and memory interconnects, caches, various accelerators, core configuration, and indeed process nodes as mentioned above. I don't think there's anything inherently faster in one ISA than the other.

There can be ISA-level differences: Itanium’s VLIW structure meant a lot of memory was storing NOPs filling unused slots unless your work aligned perfectly with the CPU and you had a brilliant compiler.

These days, I think you’re right with the possible exception of density: if you have comparable resources, vector extensions, etc. an ISA which uses memory more efficiently is going to get a little more out of its cache and memory bandwidth, but that’s probably not going to be huge.

Then I fail to understand how is Intel's perf/watt behind some ARM vendors. They probably have the best talent in the industry.
