you say that, but in practice Intel is still 5-10x off ARM when it comes to idle power.

- wmf 12y agoIs that true for Merrifield/Moorefield? AFAIK they're pretty close, but only in the phone chips.
- wtallis 12y agoRegister renaming and instruction reordering and things like that can't be selectively powered down, and are very power-hungry. But if you were talking about when the entire core is suspended, then that's largely unrelated to the high-level feature set of the processor. It's about things like the analog characteristics of the transistors used: Intel builds their mainstream CPUs using circuits that can run at 4-5GHz without trouble while none of the mobile SoCs can come close regardless of exotic cooling.
