x86 is the WORST modern architecture if performance-per-watt is considered. And extra power consumption means extra heat.

The only reason why I even still have an x86 PC is to play videogames. For all other purposes I’ve got ARM machines.

What is the energy efficiency difference between x86 and ARM expressed as %?

<1%? 1%? 2%?

That article is nonsense, even if it's up to the implementation, not ISA.

Apple's M4 Max owns AMDs top consumer CPU (Ryzen 9 9900X3D) in both, single and multi-core workloads, while consuming a fraction of power that the AMD chip does.

The year-on-year performance improvements on Apple's ARM chips are just insane. If it really was so simple, then why haven't Intel and AMD pulled their heads out of their asses in the last 5 years and re-designed their cores from the ground up?

What was so simple? CPU design?

CPU design and manufacturing is modern equivalent of 1960s/1970s rocket science, it is literally one of the hardest things we (humanity) currently engineer.

You think if AMD and Intel switched to ARM ISA then their processors would magically have significantly better performance characteristics?

yyyyyyyyyyyyyyyyyy... Lunar Lake?

According to who? And which workloads because there's countless of them and in some M4 are better and in some other AMD/Intel are better
