Recent intel systems unfortunately often push higher power to "beat" amd on performance metrics. Single core intel perf is still higher and likely will be, but multicore and efficiency of zen 4 is generally similar if not better than intel 13th gen. 14th gen helps efficiency but is barely available. Oh, and the amd igpu is quite performant, much better than the 13th gen and lower intels. Btw as someone with a skylake laptop that also used to sip power, I suspect there's been a mild across the board power increase especially as newer chips clock much higher. My ryzen 7 iirc goes till 5.1ghz and is noticeably faster (i'm at 392 tabs in edge right now) than my skylake. I suspect your older laptop wouldn't clock so high, and a 3ghz limited intel/amd would have great battery.
