Two, three GPU's. Let's end this.
Let me start this off by saying I would normally never make a blog.
I had a user send me a personal message I simply could not ignore, after the Xbox One rumors of having multiple GPU's being confirmed to not be true and as if Microsoft giving a descriptive layout of the actual APU and GPU structure wasn't enough before that either. I still have people sending me personal messages trying to say otherwise.
Anyway I had someone send this message just today, telling me to wait until the 30th, you will be proven wrong.. The same NDA nonsense. Not only that but claiming it has three GPU's, not just two, capable of achieving a total of 4.26 Teraflops altogether. As if it couldn't get any crazier, they of course used an off screen image of the GPU diagram but just wait, that is not all. You might be asking yourself how did they come up with such a ridiculous number..?
Well I will explain, what really blew my mind about this one particular message is what this person was saying, they were making up numbers that didn't even exist in this diagram. The diagram they were claiming to be reading from.
They claimed that the larger squares were all graphics processors. This is what they said to me and this is a direct untouched quote.
"grafix processer 1 = 1.95 tflops = orange square( Likely 2 DPUs working together with a cpu core or two to manage 1 probably for physics 1 for straight grafix)
Graffix processer 2 = gpgpu = 1.31 tflops = pink square (jag cores working with 12 cus for gpgpu in main soc)
Graffix processer 3 = 1 tflop= yellow square (Likely 2 more DPUs(dedicated Processing Units) working together, one for 1 rendering 1 for shading, also working with some cpu for management)"
The only square they were able to get right was the the pink one, the actual main GPU that says 1.31 teraflops. Which has been known for a long time now to be the only GPU.
So I provided them with this picture, a direct image of the diagram. One that is not off screen and much easier for them to read.
Let me ask you people, do you see three GPU's or only one? Do you see anything else besides one box that lists the amount of teraflops achieved for the GPU? I see one again. Even in the presentations off screen image, it says and I quote "GPU & GPU MMU Clients" GPU is singular, not plural.
Another thing is do people even know what an APU is? This is what an APU is, please read up on it. Here is a diagram of AMD's APU's.
All these people are assuming because Microsoft showed that split ESRAM, CPU and GPU diagram.. That it has some secret GPU and its different.. What many of you don't understand that is what an APU is.. All Microsoft did was add ESRAM.. See Microsoft's diagram.
Stacking chips is nothing new, shouldn't amaze you now with how similar it is to AMD's regular APU diagram. Its just hard for me to believe I still have people messaging me about this. When so much proof is out there that completely goes against it all.
So I cannot wait until the 30th, I thought when an actual employee of Microsoft dismissed this it would be enough but sadly far from it.
