The amount of cache would go finally on par with ryzen.

AMD had 5GHz on 32nm, while 32nm was pretty early and bad.
Why Intel wouldn't do 5.5GHz on a REALLLLYYYY matured 14nm?

Could be is a key word here. Also, 8core i9? Is that the best you can do intel?

So Intel ticktock has gone from alternative smaller process and architectural changes to instead throwing more cache at it and trying to going for GHz, in memory of the old Pentium days.....
Having said that if it gives the performance then does it matter how it is done, as long as the price is ok.

Hmm 5.5gz on 14nm. That would be 250W+ TDP then...

If this is finally Sunny Cove architecture, then it will certainly be faster than their existing Skylake architecture. Faster than Zen3? Possibly..
The extra IPC may affect the clocks they are able to achieve with it however...

I personally do not care for the Ghz. The important is the architecture, software people will find a way to exploit it to its best.

Besides high clocks, what also matters that it's gonna a be a new...sorry, a good and stable 14nm technology.

IPC increase is the result of more transistors. More execution units, more parallelization, more cache, wider data paths and so on. The entire thing gets "wider".
When stuck on the same node, more transistors mean more power used at the same clock, and obviously more heat generated.
Increasing transistor count (IPC) AND clocks on the same node while keeping the chip within allowed power envelope is pretty much impossible, and it's not like they haven't already optimized everything to the max.
If this Rocket Lake has indeed (much) higher IPC, we might see a significant reduction in attainable clock speeds as well (potentially back to 4 Ghz or so), as lower clocks also bring more efficiency per transistor.

Though they claim one of the main improvements is "SuperFin Frequency", which "First, where most of the performance uplift comes from, is the process node. Moving to 10SF and the new SuperFin transistor has enabled Willow Cove to scale better with respect to voltage and frequency, allowing for better metrics across the board".
But there was never a high performance Sunny Cove for desktop, so that is pretty much meaningless, especially since this news states Rocket-Lake is still using 14nm.
Ahh! So Sunny Cove will never make it to desktop due to their problems with 10nm I guess.
Seems Willow Cove is identical to Sunny Cove except for 3 parts. Details here;

Increasing beyond 8 cores / 16 threads is where most game-engines falter, or just don't see any advantage. You definitely don't need more than that with 90~95% of games. Sure, BeamNG.Drive will use more, and mass battle simulators/games will use more, but most game won't.
While I type this from a computer with 16 cores / 32 threads and sound like a hypocrite - entirely yes - but games just don't NEED more than that, even with streaming. So you waste TDP envelope on an extra 2~4 cores when you could just settle with an 8-core and get higher clocks (which will help dx11 games a lot as they bind on single-threaded speed at 1080p and somewhat at 1440p) with the same TDP as the higher-core count chip at lower clockspeed.
There's always room for CPU configurations higher than 8-cores in HEDT platform arena. You have better memory bandwidth to keep things running smoothly on HEDT, too.
I think 8 cores is good enough for the majority of gamers today - most people could live with an R5 3600 and be fine.
My games didn't perform better except BeamNG when I went from 3700x to 3950x, but BeamNG's traffic ran smoother then, but besides zip/render models/graphic work etc, not much is helped with going beyond 6~8 cores.
That money is currently better spent on a GPU.

Rocket Lake is similar to Tiger Lake, despite the last should have more cache L2 and the first more L3.
The problem is that TL hasn't been deeply reviewed by everyone, and if I must trust someone, Ian Cutress from Anandtech have a good point telling there isn't any improvement on IPC over Sky Lake and that Intel only wins in AVX or AI. There is an improvement in compute related to SL performance too, thanks to higher turbo and power consumption been well balanced thanks to new 10 nm superfinn lithography, but still much slower than twice the cores from AMD.
I expect Intel to show Rocket Lake the same way, faster than AMD in AVX and AI, while been hotter because of 14 nm, and much slower in compute.
If Rocket Lake wins, I think it will be thanks to software been optimiced for Intel AVX, but I don't hope so 🙄
