(www.xda-developers.com) Is Arm actually more efficient than x86?

ROAM_REFS: https://www.xda-developers.com/is-arm-efficient-x86/

* Summary

• Arm's energy-efficient computing approach has given its partners an edge in power consumption and performance.
• Intel aims to challenge Arm's efficiency claim with Lunar Lake, but improving x86 will require significant work.
• While Intel believes x86 can match Arm's efficiency, hardware limitations may hinder immediate gains.

Arm is often lauded for its efficiency; after all, there's a reason it's become the most pervasive architecture keeping portable devices going for longer. It's been in our smartphones for well over a decade (sans a brief x86 stint that very few phones took part in), and laptops are starting to make the transition thanks to the extended battery life that those machines can get.
