I don't see why people are so skeptical about this...
First of all, Intel has hired Jim Keller. He's not washing the toilets there you know...
Also, they had this long span of years to work on something like this and given the process doesn't allow them to make what AMD did with chiplets, then they are forced to do this, that is to increase the IPC massively.
Jim has been heard discussing about some upcoming core (Golden Cove or Ocean Cove) that it will support ~800+ instruction window which is some 3-4X the number that Zen 2 and Skylake support.
Another thing to note is that mobile has gained back the IPC difference during these years of stagnation from Intel so now Apple A13/A14 should be very similar in IPC to what a fully features desktop core can do, that is support some 200 instruction window.
So I think this is a good time for CISC cores to move on and get another leap in what they can do. Sure, many cores are nice and AMD has capitalized on that. But commonly used software (games, browsers even productivity apps) have yet to become highly parallel so more than 8 cores won't give you much for the next 5-10 years except for some specific cases where an entry level GPU will nevertheless do a better job than even a 3990x.
So IPC still stands as a very important metric and this is what AMD and Intel need to work on and improve. This is a metric which is much harder to improve and that is why AMD has yet to catch up with the best Intel core that is Ice Lake. Zen 2 is still some 10% worse than Ice Lake and next gen (Zen 3 and Tigerlake) might be more even with what comes beyond not being clear.
Anyway, if these rumours hold true than Alder Lake will be a big improvement and will pass Zen 3 by a big margin. And I don't see AMD being capable, technically to add more than 15-20% IPC in one generation for the same uArch.
Anyway, I hope these rumours are true.
SW algorithms can be experimented, changed / implemented easier to take advantage of parallelism than hardware redesign. Even you are just one SW guy, there are millions SW there, by what qualificantion you can say that won't happen 5 to 10 years?
