The total architectural difference is pretty small in general. Like, say switching a chip from Intel to ARM lets you make it 30% faster. For the last several decades that was insignificant. Not so much these days though.

The decode difficulty may make a 5% difference, but add in the other things people have mentioned and maybe it adds up to 30%. (numbers pulled out of my arse)

Do you have benchmarks showing this? People would switch to ARM if this is true. Note Linux and Windows runs just fine ARM.

Difficult to benchmark, but ... people are switching to ARM. You've heard of the M1 right?

Or maybe x86 CPUs were until recently designed with performance in mind instead of energy/eff and Intel+AMD were slower at going into that direction?

Just wait until Lunar Lake is released in this year. It should be x86 energy eff CPU

Intel chips have been in laptops for literally decades. I don't think that can be the reason.

In any case there's not a huge difference between power efficiency and maximum performance, especially today, because maximum performance is generally power/cooling limited.

Everything is about what goals the engineers had at the time.
