It'll probably look like that. But until somebody is playing that at an E3 demo station, I would hold off. Considering the past...transgressions.
Sony PS4: 1,8 Teraflops of GPU grunt (confirmed)
MS XBone: 1,2 Teraflops of GPU (unconfirmed, but the sources were accurate for PS4 and everything surrounding the XBone reveal; coupled with MS's reluctance to talk specifics makes the rumours pretty much confirmed)
PS4's GPU is only 17% more powerful than Xbox's
(using a base 10 logarithmical scale).
oh come on, lets keep this natural.

I think in immediate visual benefit terms, the customizations Cerny talked about that they did with the PS4 GPU, and the GPU itself, will be the biggest differentiator between the two consoles when comparing graphical fidelity of games.
Details here, first bolded part:

What happened last time ?
SF presentation was realtime they later day or two showed same demo at one of show in TV where presenter suck at that game.

Eh? They played it live at the unveiling, also on LN with Jimmy Fallon.

Really? I expect the actual game to look better.

Or this thread about the article?
Smart arse.
Ah, so it is 33% then. Thanks.

Or 50%. Whatever floats your boat.

That's an interesting read. I think for first-party games this might be quite an interesting advantage for the PS4. Sony presently has a huge first-party stable of studios which can make use of these customizations. That will certainly help the PS4 for Sony's own exclusive titles.
But for the 3rd party multi-plat titles, they'll probably dev on the Xbone as baseline and port up to the PS3. So for most of those games, the biggest difference will probably be AA level and maybe a few LoD differences like twiddlling the settings in PC games between Medium and High.

I suspected at least one of the two consoles would be significantly underpowered in the eyes of tech fanatic gamers.
Nah, the interesting part is that it'll most likely look even better at launch with extra polish and development on final dev kits. Sony first party games will blow console-gamer minds graphic wise. Belieee that.
No, it will be the bandwidth and sheer higher number of shader cores.
The things Cerny talked about are to make compute a bit easier.

The only games that will look unimpressive is EA Sports titles. Everything else will be what I expect it to be.

Its been confirmed by a lot of various websites. I believe this interview also states that (i.e. he is asked the question regarding 3GB of RAM and he doesn't deny it): http://www.gameinformer.com/b/featu...-ones-chief-product-officer-marc-whitten.aspx

3 OS need a GB each, or something like that.
I think 5GB is more than enough for games. Some people dont.
When the other console has an extra 2GB available, it is not enough.

I'm sure 5gb's of DDR3 is plenty, after all, 512mb has been plenty for years, but when your competitor has 8gb's of GDDR5 (-minus a gig or so for OS) it starts to look a little lacklustre.

It makes more sense to say 50%.
If nVidia releases a new graphics card that performs 50% better than their last, most people don't say "nVidias old card performs 33% worse than their new card". They say "nVidias new card performs 50% better than their old card". It makes more sense to use the low number as baseline when comparing.

What have you or anyone else seen to make this claim?
What if at E3, Sony says we need about 2GB for our OS.
Then its 5 vs 6. It'll just be Heavenly Sword again. Arguing how many NPCs we can fit on the screen.
they were playing it on jimmy fallon. And Jimmy played it, not some GG guy carefully acting to follow a predefined cutscene - it was clearly realtime and controllable.
I think 50% is a good overall figure for improvements
50% more GPU power
almost 50% more RAM
more than 50% more main memory bandwidth (but that'll be mitigated by the esram on xbox, plus with a less powerful GPU you don't need the higher bandwidth anyway)

Exactly.

Until a game developer shows us the improvement within their game engine. We really wont know.
If a team uses all 5GB on an XboxOne. Or something close to that. We cant understand what a 25 or 50 percent 'boost' is supposed to look like.*

Havent been on gaming side in a minute. Forgot about that exhibition.
however much ram you have is always 'enough' and also 'not enough'. as a developer you cut your cloth to fit, but will always want more.
Arguably, MS's machine is nicely balanced. For the GPU power it has, you don't need massive external bandwidth, and 5GB Ram is probably enough - it may not be able to use much more effectively.
PS4 on the other hand - when it was originally 4GB - could be argued to be unbalanced, the GPU would be able to take advantage of more RAM. Now it is 8GB it is better balanced. And as the GPU is more powerful and the bandwidth higher, it will be more capable of using that extra ram.
So I think with current specs, both machines are fairly balanced, just that the PS4 is balanced at a higher level

Well, I wouldn't be surprised if a part of the 8GB deal was to give the OS a little bit more ram. But I would be very surprised if Sony would design a bloated OS, it's insane to think that the OS needs more than 1 - 1 1/2GB ram.

Precautionary measure. 512MB may have seemed like plenty beforehand but who knows if it will later on, so why not? 7GB is still twice as much as developers first expected and 2GB more than XBO devs will have.
Oh and I agree with moniker. PS4 being 50% more powerful than the XBO makes far more sense as a comparison than the other way around.

Still blows me away every time I see it. That was the next-gen 'wow' moment right there. The moment that definitely wasn't at the Xbox One reveal.
and it uses about only half of PS4 total RAM since Sony bumped up the specs. Are you fucking kidding me Sony/GG?
How does this bode for Wii U down ports?
Go play some PC games then. The hardware here is pretty damn similar and there are more than enough games out there now that will take advantage of a GTX 680 with 4GB of GDDR5 in collaboration with 8GB of DDR3 (with about 1-2 GB taken up by the OS).
That's the kind of gap you're talking about here, just not full optimized. On PS4 and XB1 that difference will be optimized for each experience. It makes no sense to just hand wave a 2GB difference and say it doesn't matter until you see it.
I'd assume they just straight doubled it. I wouldn't even be surprised if the OS memory is effectively "discrete" from the rest of the system, so going from the 256 chips to the 512 chips would inherently have doubled it even if Sony wasn't 100% positive they'd need all of it.
Sony got caught with their pants down on OS utilization last generation and had to make a lot of sweeping improvements to remain competitive. I wouldn't be surprised at all if they're future-proofing the PS4's OS allocation when they can do so and still maintain great hardware symmetry and a competitive advantage over MS.
But it's not comparing PS5 to PS4 or 360 to xbone so your analogy doesn't fit. It's comparing the new number (for the xbone) to the already known numbers (of the PS4), so doing the 33% one makes sense. Of course both are perfectly viable depending in the point of view.

Wii U is to Xbone/PS4 in the same way Wii was to 360/PS3. A different generation in terms of hardware.
The Wii U is incredibly doomed at this point from the standpoint of 3rd party development, in much the same way the Wii was.
Also true.
It makes sense to start from the newest product. Eg. our new care has 33% less CO2 emission, rather than, our previous car model had 50% more CO2 emission.
Big numbers sound better though

I still don't understand it after thinking about it a few hours. Well then, I was always shit @maths in school.
GAF isn't very good at math unfortunately
Here's my attempt.
PS4 = 1.8 TF
XBO = 1.2 TF
Difference = 1.8 - 1.2 = 0.6 TF difference .. So by what percentage is PS4 (GPU) better?
0.6/1.8 * 100 = 33% MOAR FLOPS
If you compare both GPU's directly you get 1.2:1.8 = 2:3 POWER RATIO
TLDR; PS4 has a GPU that can output 33% more than XBO .. Is that a huge difference? Only the games will tell us. But there are many other factors like CU, RAM etc
Fixed

The ps4 has 50% more flops than the One.
Difference = 0.6
XOne = 1.2
Oh look the difference is half of XOne or 50% as some might say.
Difference = 0.6
