is that a wish or a factual claim?

They intentionally clock the CPU down (it is still a Jaguar CPU) and the GPU has two modes - one for Pro, one for standard PS4.

The Pro will behave exactly like the standard PS4 when running standard games.

Wait, so CPU gets downclocked as well? I thought it was just GPU getting downclocked in unpatched games.

Keep in mind that most games that drop frames on regular PS4 do that because of CPU, not GPU.

That's why reading it downclocks CPU from 2.1 GHz to 1.6 GHz as well makes me more worried than downclocking just GPU.

It makes little sense, how CPU clocked higher could make unpatched games run unstable? GPU maybe since it's a different more powerful chip, but the same Jaguar CPU overclocked? What? Cerny you alright bro?

Look at it this way. As far as consumer tvs go, we hsve 1080p or 4k. Noe there is only so much the PS4pro can do for 1080p. As it stands that's basically supersampling which is a natural benefit from it uprendering the games to begin with, HDR, lastly better (more stable) framerates. Those are the universal gains that we most likely will see with every game running on a Pro in 1080p. Then we have the dev based things like better shadow details, more on-screen effects or objects....etc.

If you are buying a PS4pro primarily for its 1080p uses, then I honestly feel you sre wasting your money. It's why there is a cheaper PS4 that is optimized for 1080p content. The PS4pro will first and foremost be measured by how it handles 4k content. That's what it's designed for and that's the market it's going for. Its 1080p benefits are just a bonus. 

I really do not see why Sony (or anyone for that matter) will market something that's been championing 4k gaming from its inception (even it's first leaked code name was PS4k) by showing how good it is as a 1080p machine. it just feels like you are asking the wrong questions of the PS4pro.

And as far as it being worth spending money on, I really don't get it. There is a $300 PS4 and a $400 PS4pro. You don't "have" to buy a PS4pro if you aren't interested in what it's primarily designed for. For someone like me, that is buying my first 4k tv, the PS4pro is a must have addition. And i planned ahead and sold my PS4 over s month ago just to endure I'm not dropping another fresh $400 on the Pro. Again I feel you are asking the wrong questions. It's almost like you don't understand what the PS4pro is designed to be. Even though it's been made glaringly obvious. Evident by the complete lack of 1080p material on it. 

This is like asking how good a jet fighter is as a passenger plane.

The downclock and shutting down of half the GPU is only for PS4 games that don't get the PS4Pro patch to be sure there isn't any gamebreaking bug. So for any game that have a patch it will have improved version.

The upscalling (maybe not checkerboard) will be done even without the patch, the improved fps I haven't see any info on it happening without patch, but if sony locks the CPU then it won't happen.

But to people thinking no bugs should happen from having higher speed CPU on the same architeture that isn't true. Some bugs may appear only if by faster processing speed.

Man I'm really not sold on the PS4 Pro. I've watched a few comparison videos, 1080p and 4K and I barely see a difference. All I see now is diminishing returns. I'm sticking with my first gen PS4. 

I know it's only for PS4 games on Pro without patches which is the majority of the PS4 games and that is what we were discussing here.

But I wonder how MS manages to do that and Sony doesn't. I have yet to hear of any game having bugs on the S due to the slightly higher clock and faster esram.
