Ok that makes sense.  I just did some more digging and see that vgLeaks is confusing a SIMD with a CU because here is what they say about the PS4 arch in this artical.

http://www.vgleaks.com/worl... 

 

UPDATE: some people is confused about the GPU, here you have more info about it:

Each CU contains dedicated:

- ALU (32 64-bit operations per cycle)

 

 

This is from vgleaks concerning the PS4 GPU specs.  From there statement they are saying that the ALU executes 32 operations per CPU clock cycle.  Which would mean either the CU unit on the PS4 has only 2 SIMD or they were just wrong in their assessment.

I think that was what happen when a non-tech site (VGLeaks) leaks tech info.

What happened in here? -_-

Is them being similar that big of a deal that you all are going to argue about it for 9 pages? What is the big deal here that everybody has to argue?

It's a civil conversation.  What more do you want?

 


Some of it yes, all of it, not even close lol

Is that a fact? Where did you get this info? 

In one of the PS4 GDC conversations, a Sony exec is talking about the features of the PS4.  Two of the features discussed would require the PS4 Eye.  The use of the controller similar to the Move, with the camera being able to detect the controller position, and the ability for the controller to identify the player by controller color, and positioning the split screen based on where the player is seated.

So player 1 is always Blue.  Player 2 is Red (?).  Player 3 is Green.  Player 4 is Yellow(?).

None of these features were discussed as optional, but rather OOTB experiences.  Features that developers are programming for, and gamers should expect the PS4 to include.

Well, probably, but I wouldn't go as far as say the "DS4 won't work without the PSeye". Surely you can just use the controller without it even if you don't get these optional features, which quite frankly, don't seem very relevant for basic functionality/navigation. Nothing is confirmed though, so sorry to break it to you, but you shouldn't be stating this as a fact.

I don´t know why people are fighting for.

The only way PS4 to be significtanly more powerfull than the next Xbox is that the PS4 to be significtanly more expencive than the next Xbox.

Well, the 360 was release one year prior to the PS3 and cheaper, however few games have shown that the PS3 was any better.

Sony can´t do magic in the hardware, but Microsoft can do magic int the midware or SO.


The next Xbox may be less powerful to reduce the costs and price if it will indeed come packed with Kinect 2.0 in as standard.


Doesn't the PS4 come with PSEye as well?

Again, according to VGLeaks. http://www.vg247.com/2013/02/08/ps4-could-come-bundled-with-a-dual-camera-playstation-eye-rumor/


Not likely, they would have talked about the new PSeye at the PS4 reveal if it did, as it would be a major feature.

 

VGLeaks is not accurate now?!



Imagine not having GamePass on your console...

DIfference is one is performing 64 threads while the other is doing 32.  As I stated this is what the poster draws his conclusion that the 12 SC or Shared Cores he likes to called it is actually an Array of 4 CU cores instead of just being one CU core.

No. You are reading wrong... the memory mapping is 64bits not 64 threads and each CU have 64 threads.

VGLeaks just use wrong terms.

- as SMID is CU (in vgleak term)

 - each SMID = 64 thread lockstep (Vgleak term) 
 - each CU : 16 Operation /cycle across 4 ALU = 64 ALU per cycle/lockstep

 - in Vgleak term Thread = ALU
 - in vgleak 1 Operation = 4 Thread

Edit - Fixed.

OK, I am quoting my own post because I wanted to make clear why it seems that vgleaks is confused about what they are saying concerning the Durango SC Unit.  What could be happening here is that their diagram has the wrong terms or names which makes a big difference in how you view this content.
Here is the breakdown of the SC unit in durango from vgleaks

http://www.vgleaks.com/durango-gpu/sc_durango/

If you change the SIMD to CU then you start to understand why this could be a blunder by vgleaks.

Now here is where it gets interesting.  This is the breakdown of the 7970 AMD card, does the diagram look very familiar

http://i.imgur.com/g61Dtdy.jpg

Could it be that the SC or shader cores on the Durango are an array of 4 CUs instead of 4 SIMD.  If so, then the Durango has 48 Cu instead of 12.  Could the Durango actually have a 7970 (actually a little better as the 7970 only has 32 CU).

It doesn't seem likely to me, it's all rumors at this point anyway. Again, they would have talked about the new PSeye at the PS4 reveal if it did, as it would be a major feature.

It depends:

accurate = good for sony, bad for ms

inaccurate = bad for sony, good for ms

I just do not have time to find the statement but I could have sworn that Sony sayd that the PSeye will be included with the PS4.  It just doesn't seem smart to make your default controler do all this cool little stuff take the time to develop, test and make the actual device it needs to use those features optional.  Seems kind of silly if you want developers to use a feature but it requires consumers to purchase another device.

I am will to put my money that the chances of the PSeye not being included with the PS4 is much slimer than it being included.

So? does that confirm the DS4 won't work without the Camera as he says? Does that confirm the Camera is packed-in with every console? they didn't talk at length at all, they barely said like 2 sentences and showed a picture.
