Is Apple ahead of x86/64 on width?
The A10X article on anandtech seemed to imply that every other ARM architecture was far behind on width while Apple was mostly on par (or slightly behind) x86/64.
- mbell 8y agoApple doesn't release the details but Anandtech estimates A12 has 13 execution ports (https://www.anandtech.com/show/13392/the-iphone-xs-xs-max-review-unveiling-the-silicon-secrets/3 https://www.anandtech.com/show/13392/the-iphone-xs-xs-max-re...). I'm guessing the numbers for 6 ALU ports are more accurate than the overall since it's hard to blackbox determine the port sharing structure. Recent Intel / Zen have 4 ALU ports AFAIK.

The A12X doesn't have the liberty of a desktop form factor, so it is definitely a mobile part, but it seems reasonable that Apple could make another chip that scales the performance up even further if they wanted to, without really altering the underlying architecture.
