Could be the low power ecores being in use somehow? Meteor Lake has 3 types of core with 2 lpE cores in the SOC to try to turn off the Main P and E core tile. Lunar Lake removed the lpE cores and it does feel faster when surfing pages like reddit than my 12th gen and 5000hz laptops. I also tried the Ryzen AI and it is pretty close but 20% less battery life. They get a pretty crazy 15hr battery life now.
