For 5000 they did that yes, but for 6000 it's different: https://i.itworldcanada.com/wp-content/uploads/2022/01/amd-ces-2022-ryzen-6000-mobile-8.jpgThe first one is the 30% figure being referenced I presume? In which case note that the claim is that the processors can use up to 30% less power, not the system. Page 8 of this AMD presentation comparing the 4000 series mobile to 5000 series illustrates the difference, and in that case how battery life can increase more than the power reduction in the processor - https://www.amd.com/system/files/documents/battery-life-whitepaper.pdf
The only way for Intel to be significantly better is to go on-die PCH like with AMD. Yes, AMD had that since pre-Ryzen but they were behind in power management.What I'm currently more interested in is how ADL will compare to TGL in battery life. Substantive claims on that aspect were suspiciously absent in Intel's announcements. There are obviously going to be improvements compared to TGL, but to what extent will have to wait for reviews I guess.
Meteorlake with Foveros is the first generation that'll make it possible, as it becomes an effective on-die, or will get close to it. Of course possible doesn't guarantee it as Lakefield demonstrated.
