To me it appears that Intel pulled out all the stuff they have been working on the last 10 years, and crammed it into Alder Lake, just to get the crown back from AMD, and thus get more sales. They appear to be quite a leap in performance, compared to the previous chips. Funny how that just suddenly happened.(
Suddenly???
Gen 10 ( Ice Lake ) -> Gen 11 ( Tiger lake ) -> Gen 12 ( Alder Lake )
It took three iterations to get running on what started out as a revised 10nm foundation. ( Skipping Cannon Lake that didn't ship across wide line up).
The implication that Intel was waiting around with a finished enhanced SuperFin in the labs for the last 3-4 years just waiting until things got just bad enough to introduce is a bit misguided. A substantive portion of this is because they screwed up. It is taking a long time to dig their way out of the hole.
They are also not particularly wining top performance title on mobile laptop either. At least with the iGPU. Those E cores a capping what they can allocate for GPU cores.
In contrast, they have been in a screwed up state so long ( ~ 4 years ) that the more deliberate workarounds started several years ago are starting to come out of the pipeline. ( I suspect Rocket Lake was a mindfart that someone started on a shorter than usual design cycle time that not surprisingly produced less than reasonable results. )
Gen 13 ( Raptor Lake) that will coming late 2022 -early 2023. More "pour E cores on top" workaround solution. Pretty good chance it will bleed even more power on a bigger die to win several of the tech press's favorite tech porn benchmarks.
AMD only have a few years, before they are both on the same node, and in that case, AMD needs to up their chips it seems.
AMD just needs to stay on the steady, methodical update path. AMD has not shortage of competitors besides Intel ( battling Nvidia also . The Windows ARM solutions like Qualcomm 8cx gen 3 are just plain slow anymore. Server Arm solutions . etc. ) Competitors coming from multiple directions .
Intel seems to be trying to pull the exotic , off the wall solutions to try to leapfrog back. Decent chance one of those will have blow-back down the road.
