Actually since that Sandy Bridge and to 2017 there wasn't much of real things around the corner and high end CPU stayed high end for many years.
And since that Intel has been more interested on pumping butts of users... err price tags than providing real performance/cores per money advance.
Actually Intel's CPUs are all rehashing of same 2015 6th gen Skylake architecture...
With new motherboard need being completely artificial and Intel just butt raping and robbing consumers:

And with whole lots of vulnerabilitites from lots of very old design parts in architecture.
Just Google for Meltdown, Spectre, Foreshadow and Spoiler.
With all the money and resources you would have thought Intel to have fixed those short cuts in speculative code execution.
Only thing which saved Intel is that for first gen Zen architecture AMD was stuck with second rate GlobalFoundries, who uses originally Samsung's tech designed for phone/tablet CPUs.

That has limited clock speeds and single core/thread performance behind Intel.
Zen2 computing dies are made by TSMC on more modern than Intels 7nm High Performance node designed for high performance parts from the start.
In CES AMD demoed engineering sample matching 9900K's processing power at ~50W lower system power consumption.
Also chiplet design rumoured in last December got confirmed.
Shown CPU package had empty spot the size of another 8 core computing die and AMD strongly hinted about pushing forward in core counts and performance per price.
So 8 core/16 thread model is likely sub £250 mainstream model, with hundred more getting 12 cores/24 threads.
Though I don't see Intel being in hurry to lower prices to real value level, when people just ask more raping&robbery.
At least launch of Zen2 Ryzen line up should be in Computex.
Apparently it has been getting PCI-express v4.0 chipsets ready for new motherboards which has delayed release.
