Not so simple, it depends on the game. The XBO has the same CPU as the PS4 clocked at 1.8ghz instead of ps4's 1.6ghz, by that logic the XBO should have higher framerate than the PS4, However in almost all instances it is the PS4 version of games with the better and more consistent frame rate even though it has a weaker CPU. So we can come to the conclusion that in the majority of console games it is infact NOT the CPU that is limiting the framerate.

The earlier leaked specs suggested the NEO would use the same CPU as the original but clocked at 2.0ghz instead of 1.6ghz.

Mind that these are generally small differences. Like PS4 at stable 30 fps and X1 with drops to 26 or something. And in a lot of these cases, companies are pushing for similar or equal resolution and that will make the X1 struggle more. 900p vs 1080p has been a sweet spot for multiplats because this difference in pixel count is roughly the same power difference for the GPUs.

Now 30 vs 60 is a way, way bigger problem. You have to halve frame render time. It's not like we are seeing games running at 60 x 30 or 30 x 15 when talking PS4 and X1.

As they are pushing for parity, it's reasonable to have a CPU that's only a bit better. Upgrading the GPU will allow higher res and better effects but without making the regular model look far behind. Remember, they won't stop selling the regular version. You can count on a price cut or even a slim model.

Last gen, they suffered with extremely outdated consoles in the final years. It's impossible to make it cheap and powerful at the same time. So now they will have a cheap model, that runs all the games and is affordable, and a premium one, to make power users happy.

I thought the whole point of GPGPU compute was allowing the GPU to offload some of the workload from the CPU for labor intensive tasks. I did research on this quite a few months back and to my understanding, GPGPU compute is not generally practiced in game development but rather in things like video editing and so on. If that's the case, and since we know that the first Ps4 is heavily unified, wouldn't it stand to reason that the GPU could help with framerates for games that utilized such a feature? (Most definitely it would just be in exclusives, but the first party titles Sony has put out have very consistent framerates. Even BloodBorne which comes from a series that is known for its performance issues)

Doe anyone else think that the Giant Bomb leak may not have been final hardware? I mean, if it's going to use the RX480 why would they down clock it by so much? It already seems like an efficient GPU and it's really inexpensive.

So? Maybe we'll see a regular RX480, and a more significantly upgraded CPU? Just a thought.



Bet with Adamblaziken:

I bet that on launch the Nintendo Switch will have no built in in-game voice chat. He bets that it will. The winner gets six months of avatar control over the other user.

How will a neo even work? Will we be able to put our old/current PS4 games in and they will just somehow run? (presumably with better fps) Will devs need to put out a patch? Will devs even bother? if past PS4 games dont work doesnt that mean its essentially a PS5?

Well, think of it like PC.  If you replace your card, in general games will still run, only better.   Devs have to bother according to the leaked docs.  All games released after October must be have a Neo mode.

4.2 TFLOP is a solid interim upgrade, but I think I will wait for the 6+ TFLOP XBox 2.

Of course it may not be the final specs but the clock isn't that much under spec.   There are so many things we don't know but it is still quite a jump for a console.   And since consoles get more bang for buck due to less overhead, this basically ensures that all game can run at 60FPS.  I think people will be pleasently suprised.   You are basically looking at all game running at 1080p on Ultra.  I would like the Neo PS4 and I will probably get the 480 for my PC.

Wait over a year?  Even if it is more powerful when it releases (and by God it should be), I think Microsoft is taking a big risk here.   And if we are wrong about the Neo and its at 6+TFlops, then Microsoft has a real problem.   I see very few people willing to wait a whole year if its power they want.

Unless I am mistaken... I don't think anyone doubted it wasn't going to be that a few days ago... We just had people doubt that its going to be running at full 480 clock speeds which is still yet to be proven for obvious reasons...

PS: If it's the thread we are thinking of, I was the first one that suggested it :P http://gamrconnect.vgchartz.com/post.php?id=7921263

But having less Mhz isnt that much of a difference, stream processors are. There are various Graphicscards from different companies of the same AMD GPU with higher clock speeds than orginally intended by AMD, yet the difference is quite small in performance.

Also Sony could easily decide to increase the clockspeed in the last minute, just like they increased the GDDR5 ram from 4 to 8 Gigs for the original PS4.

It does matter if we are trying to calculate Flops...

The way you calculate it is... Number of Cores∗Average frequency∗Operations per cycle

 

2306*0.911*2 = 4.2 Tflops. (Ps4 Neo Rumoured clock speed which in terms of other specs, has been right so far)

2306*1.2*2 = 5.5 Tflops. (480's clock speed)

Of course, Flops doesn't directly translate to real world performance but if we are trying to use it as a relative unit of measurement, mhz does matter... And sure they could increase the clock speed but it is a lot harder to do due to heating issues than just to add in more ram... Specially if they are aiming for a slim model (Not saying it is going to be slim but if it is...)

Nintendo is screwed.

I suppose Scorpio could come out in spring/summer 2017 instead, so it wouldn't be quite a year, if its not coming out by then, then the reason likely is they are using something like HBM2 RAM, which would be net performance even higher, so all the more reason to wait. 

There probably are not that many games that will use the Neo's power until 2017 anyway, so I'm kinda content to wait and simply get the better hardware. 

For VR I think I'm going to go with Occulus Rift too. Compatible with PC and better quality resolution ... if you're to pay like $700 for VR, I figure you may as well pay a little more and get the best possible experience as VR is not exactly "budget" either way.

Soo it wont be a big 5.5tflops upgrade and will fall verry behind the nx and scorpio? 

You've got to be joking. The NX based on its own leaks isn't even in this conversation since its rumoured to be aboit as powerful as the XB1. there are even rumors that state it wont use an X86 architecture.

And as for power, going from a 1.8TF to a 4.2TF GPU, bump in CPu clock from 1.6Ghz to 2.1Ghz and memory bandwidth from 192 to 218GB/s is a significant bump especially when you consider that the standard is still 1080p@30fps. Even if the XB1scorpio comes in at 5.5/6TF you wont notice any marginal difference when looking at 1080p content. It will be like comparing two systems @1080p where one hits 48fps and the other 40fps but both are locked to 30fps. 

Also keep in mind that in situations like these, the PS4 will still be the lead platform for devs. Lastly, no matter what sony or MS does with their upgrades, they are still limited by the current hardware. Games would be built to run on those first befire any added benefits of the newer hardware is considered.
