It's the price Intel pays for making chips that clock higher than AMD on a less dense node. Meteor Lake is significantly denser, and doesn't clock as high, so it'll be interesting to see if Intel has managed to improve performance/W.
Not that AMD is in a great spot either, even the monolithic chips seem to have quite high idle power draw. The Snapdragon X Elite will hopefully shake up the laptop market significantly.
I've no idea why all of a sudden everyone's concerned about idle power consumption!
Anyhow, it's just a myth that Zen4 has high idle power draw than Raptor Lake. Per Guru3D, the Ryzen 9 7950X3D has a total system idle of 78W, compared to i9-13900K's 69W. That's only 13%.
And in single and multli-threaded application, the 7950X3D draws 114W and 264W, respectively, compared to 13900K's 124W and a whopping 368W.
And let's not forget that the 7950X3D is a chiplet based CPU with high-bandwidth interconnects and a massive 32+96MB 3D V-Cache on-board. The fact that it's only marginally more power hungry than the monolithic 13900K at idle is quite an achievement.
Alder/Raptor Lake is also an idle stinker. There's a reason battery life has regressed since 11th gen Intel
