Anyone that thinks their GTX 660/760 or 7850/7870 is going to outperform PS4 for a long time to come will be in for a surprise. Not saying they won't be able to play the game, just they won't be able to reach PS4 level graphics on multiplats in the next year or so.


Yes they/we will. I never bothered with a multiplat on consoles last gen either.

PS4 vs. Xbox One: GPUs compared

Again, by virtue of being an AMD APU, the Xbox One and PS4 GPUs are technologically very similar — with the simple difference that the PS4 GPU is larger. In PC terms, the Xbox One has a GPU that’s similar to the (entry-level) Bonaire GPU in the Radeon HD 7790, while the PS4 is outfitted with the (mid-range) Pitcairn that can be found in the HD 7870. In numerical terms, the Xbox One GPU has 12 compute units (768 shader processors), while the PS4 has 18 CUs (1152 shaders). The Xbox One is slightly ahead on GPU clock speed (853MHz vs. 800MHz for the PS4).

In short, the PS4′s GPU is — on paper — 50% more powerful than the Xbox One. The Xbox One’s slightly higher GPU clock speed might ameliorate some of the difference, but really, the PS4′s 50% higher CU count is a serious advantage for the Sony camp. Furthermore, Microsoft says that 10% of the Xbox One’s GPU is reserved for Kinect. Games on the PS4 will have a lot more available graphics power on tap.

And the reserve for Kinect is gone so only 40%.

Well and faster RAM for PS4

Nah, The 50% power difference, is the on paper power difference.  Whatever was reserved for Kinect (in this case 10%) makes that a 60% power difference.  Removing Kinect simply put it back to the normal 50%

PS4 has a lot of advatages over a 7850 or 7870. It has the 8 ACE / 64 Queues setup only seen on the R9290x. It also has access much more RAM than any variation of the 7850 or 7870 ever did. It is also connected in a way vastly supirior to PCI-E.

The PS4's ability to utilize more memory, comunicate faster CPU <-> GPU, Perform GPGPU operations, and fully utilize every CU in the GPU make it punch above either of those cards, and this even before the improved development enviornment.

Anyone that thinks their GTX 660/760 or 7850/7870 is going to outperform PS4 for a long time to come will be in for a surprise. Not saying they won't be able to play the game, just they won't be able to reach PS4 level graphics on multiplats in the next year or so.

The 760 is already better than the PS4 architecture. Graphics cards all have dedicated 2-3 GBs DDR5 memory, which keeps them up to speed for the most part with the PS4, and core for core Intel PC processors have a huge advantage over performing tasks than the PS4's 8 cores do. Just because the PS4's GPU has access to a bit more "dedicated" memory, doesn't change the fact that the real-world performance is equivalent to relatively weak mid-end cards.

WThe reason I put "dedicated" in quotations is because it really isn't dedicated for the graphics. The RAM is shared with the CPU, which eliminates a good portion of it in actual use (and with only 5.5 GB available for game use, that could be a serious issue). With PC, the graphics card always has access to 2-3 GB DDR5 of dedicated memory, and then the system has 8 GB DDR3 more for the CPU to utilize.

Yes new Card will be better but what KGB29 Said still hold true. I have a state of the art PC , but still love Vita :). 

His comment about memory utilization was wrong though. The PS4's GPU has no access to dedicated RAM, it shares 5.5 GB with the CPU, so it doesn't have much more available RAM at any point than the 760 in actual gameplay. 

In the real world, the difference between the PCI-E setup and the PS4's direct setup is relatively negligible overall, as seen by all these different tests which show it only managing to keep pace with the 7850, not above it.

Well I also showed some text and I know PS4 will release more than 5,5 GB RAM in the future..still i dont know about all graphic Card so you can be right !

Still I see Uncharted 4 preview that knockas my highend PC back. 1080/60 and that performance for 399 $ impressive !

He said it has access to "much more RAM", which isn't true, since it has no dedicated RAM. And dedicated RAM was a bad point on the PS3 because the PS3 only had 256MB of it for the RSX and 256MB for the Cell, which in a way crippled both.

And I'm not talking about optimization, I'm talking about pure graphical power. (And PCs have mod optimization to help as well, btw)

Fixed.  

By that logic, you don't have access to a fridge, because you share it?  

The advantage of dedicated RAM, is that the developer can choose where to put stuff.  Dedicate 1 GB to the GPU, and 4.5 to the CPU?  Done.  Dedicate 4.5 GB to the GPU and 1 GB to the CPU?  Done.  Bam, this GPU has more than the 2/3 GB that "most cards have."

Fixed it in an edit myself right after posting, sorry.

And your example is off. The CPU will in almost all cases be needing just as much RAM as the GPU, especially if you are playing a high-end game with a lot happening on the screen. In that case, the GPU suffers because the CPU will be using 3-4GB of RAM, leaving little for the GPU, or vice-versa, so the dev has to choose between optomizing for the CPU or the GPU with RAM. When you have dedicated graphics, the GPU can use all the memory given to it with 2-3GB DDR5, and then the CPU can use all 8GB available to it, without running into problems.

Now, if the PS4 had 12GB of RAM, with 9GB available for devs, this wouldn't be a problem, as both the CPU and GPU would have plenty of room to work with, but that isn't the case. 5.5GB for both gives little breathing room if needed.

To be fair, that preview was not gameplay, just a short rendering. It's doubtful that Uncharted 4 will look that good.

Plus, with a highend PC, you can get 4K resolution and 120FPS

haha..yes i like high FPS but 4k have to Wait due to; no 4k tv is fast and hdmi cant support 60 mhz.

What?  So, then what is the use of having 8GB for the CPU and 3 for the GPU in a PC.  That means you should only have 3 GB for the CPU.  

Killzone used 3 GB for video memory and 1.5 GB for other things.   

‣ Three memory areas

‣ System - CPU   1,536 MB System

‣ Shared - CPU + GPU  128 MB Shared

‣ Video - GPU  3,072 MB Video

There are no problems with having shared memory.  

There are no problems with having shared memory, but there is with have little shared memory.

And I was referring simply to the PS4, not PCs in the GPU/CPU memory optimization. For PCs, 8GB of memory can be utilized to have much buffer space than the PS4, period, because 8GB of dedicated RAM is much better than 3GB, and a good dev will use up as much RAM as they can to speed up their games.

And in Infamous SS, most of the memory available went to the system, with only 1.5 GB of memory dedicated for the GPU.

So, exactly what I said.  Not quite as far as my example went, but it does prove you wrong.  

Not really. It shows that it makes memory usage much more constricted when you only have 4.5-5.5 shared RAM.
