This is false, check out the tests. You cannot use the power numbers from their 5800U overview, they are incorrect.
It's not "false" or "incorrect". They are based on numbers from real reviews. The problem is that they average out the numbers, which is what makes exact comparisons very difficult.
Alderlake's big gain over the predecessor is in an area where the market couldn't have cared less, otherwise Renoir and Cezanne would have took significant marketshare. Actually maybe this is a bit of AMD's fault too, but still.
Trust me, I embrace the hybrid methodology and love the E cores but like I said before, Intel's silence regarding Alderlake-U/P is deafening. These guys love to tout their horn, why the silence? Intel's CES presentation was a snoozefest. Not one mention really?
Because probably, maybe, umm, it loses in MT significantly despite the massive gains, the battery life is nothing special and probably behind, and of course the iGPU is slower too. The latter two I bet you the market cares much more. If they have an AMD convertible under 2.5lbs and if I was looking to buy one now, I'd be seriously tempted.
Intel had a massive battery life lead with Haswell, extended it with Broadwell, regressed a bit with Skylake but brought new features for more fine tuning, and Kabylake made it really good.
Icelake and Tigerlake
regresses on that department. Man, they have so much more work to do! This part
will not be fixed until Meteorlake at the earliest.
