For someone claiming others have reading comprehension problems you seem to be the one with it.
He said that with previous paradigm on GPU development 2Ghz was unreachable (not that PS5 couldn't reach it, but that GPUs didn't get that far, just look at Xbox for examples, or current gen or all other GPUs). But they were able to work around that paradigm and get over 2.23 (it can go further but then it would be unstable, so you also got your answer of it being able to run at 2.23 most of time, and they can't say if it is 50, 80 or 99% of the time because that will be a game by game depending on the developer not the HW).

You seem to have lost the ride. Be happy believing what you want. Just because you don't agree with me doesn't mean you are right. You just disagree because is your choice and opinion against an established FACT, and I will respect that.
But I use facts and references, before even argue. I do not let my loyalty to Sony interfere. Being Loyal is one thing, being a fanatic is another one. That kind of fanatism can have devastating effects, such as the ps3 being a disaster at the beginning. The constant denial of facts, the experts written articles and Mark Cerny own words can be defined as a FANATIC behavior. Twisting reality doesn't make a thing more real my friend.
Previous Paradigm means obviously the way it has been until now, just like the PS4, PS4 Pro, XBOX One, XBox One X, and the new Xbox SX did. A fixed clock frequency with a fixed performance capability. How much tutoring do you need to understand something so simple?
Still, you wanted to argue with me just for the sake of arguing, yet you say the same as me in your last sentence; "...they can't say if it is 50, 80 or 99% of the time because that will be a game by game depending on the developer not the HW..."
I want to be myself clear. I support Sony, I want them to succeed. I wish they end with a powerful and balanced system for the next PS5. The changes and new features that will be available for the PS5 will be without doubt a game changer. I'm not debating that. I didn't support Microsoft this generation, even when they ended with the most powerful console. There is a kind of linearity with brands, hardware and games content, that adheres itself like a recipe for a successful console launch. And that is where I'm being properly critic of it.
Mark Cerny is talented. But he already made mistakes. The PlayStation Vita was a total fail because of him. Also the Pro system didn't exactly hit the nail. He didn't want to listen back then. I don't trust him specially when he evades simplistic logic and instead uses unusal terms. Like the use of the stupid paradigm word, just to evade to say "like before". I can assure that some people here will put their life on the line thinking the PS5 will have a paradigmatic ability, just because Cerny said something about that, and that will beat the crap put of Xbx SX. Please.....
I love and enjoy new technology, but there is a limit with it. If you live with a technophilic style of fetish, it will be harder to accept other critics even when their claims are true. Focusing in non essential features is waste of resources, when 90% of the potential buyers do not care about them. And I'm gonna put myself in this example, because I may be too part of the other 10% that I hardly critic. I wanted full BC features for the PS5, but if it gonna cost too much and risk again a ps3 style meltdown in Sony's cash, I really do not want it and just BC for PS4 titles will be enough. For the PS5 to be a success, it will need to be affordable, and I had to accept that whether I like it or not, even if i could pay $10,000 version of it. If you really love Sony you should now what to ask from them and what NOT to.
There is a north with the core values already established since the PS One launch; Power, Capacity and Affordability. PS2 followed the recipe and was the greatest success in gaming history. The PS3 system wanted to change that core recipe and failed. PS4 retook the original north and found again major success. I believe Cerny genuinely wants PS5 to be a success, but in my opinion he is not following the previous established road. Some details of his PS5 vision are a risk, a risk that I don't want Sony to take, at least now now.
And finally...If I have to be a newbie, an ignorant, and an uneducated because I use hard facts, references and truth...then I will gladly be one. Have a nice day.

CPU and GPU don't always run at max frequency and always trying to run at max frequency means they unnecessarily ramp up with little to no workload (race to idle). I think that's what Sony has been trying to address, all the way back from when they announced the ps5 to be a greener console. (Which was met with instant backlash)
For example a car analogy. Imagine you apply constant throttle yet to keep the speed constant on a hilly road you disengage the clutch (switch to neutral) for a bit 30 times per second (waiting for vsync). The GPU is the engine, what happens to the engine with constant fuel supply and no load, it revs up then down again when the load comes back. This produces extra unnecessary heat and also consumes more fuel (power). So basically Sony is trying to implement a cruise control for console, adjusting the throttle based on the predicted load.

Excellent analogy. I suppose there is a special API or module built-in somewhere for that special task...maybe at the cache level of the I/O Complex, that way it retains all data at the memory to maintain bandwidth without performance drop whenever the PS5 need to use the cruise control setting you described.
In an ordinary PC, constantly changing frequencies at a software level produces a staggering/chopping effect whenever the GPU clock is too high. Flashing/hacking vbios is better if you know what you are doing. If PS5 drops CPU voltage to maintain GPU, it will need to sustain somewhere for a brief moment the change of output power, and that requires more transistors or a better process to build them...and is probably the reason why PS5 CU's are bigger than previous generation CU's, but even more surprising when taking into account that the PS4 node process was 14 nm and the PS5 is 7nm. If you want to tolerate more voltage for a higher frequency you need more better capacitors and heatsinks, across all the board not just transistors(main die).
