This article is from April. Me, and many others on here it seems listened to Mark Cerny when he spoke. He addresses using edram would have been a complication and a UNIFIED MEMORY SYSTEM is better. That statement he makes tells you that you cannot have hUMA with an edram chip on die. Then there is the fact that AMD confirms this. Then you do a little research on what hUMA is and what it means. Finally you mix in a little logic, and wa-la.
Your tons of evidence comes soley from MS and one "retracted" statement from AMD. Do some research and stop repeating things MS talking heads have been saying. These guys have been lying through their teeth since the reveal, yet you take their word like it's the gospel.

He said it was a complication, not impossible. A complication means there is a hill to climb, not an impassible wall.
If you look at the memory diagram that I posted, you could have the DDR memory operating under hUMA and not include the ESRAM. This would mean the GPU would need to copy any data to the ESRAM or back to the DDR RAM. Not a big deal, because the ESRAM is reserved for the GPU anyway. The DDR memory would be unified and accessible to both the CPU and GPU. Or you could have the hUMA operating on the DDR memory and the ESRAM as two separate memory sets. The CPU and GPU would still need to copy memory to the ESRAM but the they would be able to access both the ESRAM and the DDR memory and address the same memory space. The only difference is that the ESRAM would be reserved for graphics only.
And again. Microsoft's developer documentation and during the Architectural Panel held during the reveal, Microsoft has said they're using coherent (heterogeneous) memory. This was confirmed by VGLeaks, this was also confirmed today by XboxOneDev on Reddit (who has been confirmed previously as an Xbox One Developer by the moderators) and lastly it was confirmed by Microsoft back in May during the Architectural Panel by the Distinguished Engineer Console Architect Nick Baker.
"We have to invest a lot in coherency throughout the chip. So there's been I/O coherency for a while but we really wanted to get the software out of the mode of managing the caches and put in hardware coherency for the first time on a mass scale in the living room on the GPU."

And because you don't believe me, here is ARS Technica's article on it:

At the end of the day, which this definitely is, the bottom line is that the PS4 is where it was yesterday. It features hUMA. The Xbox One also features it, however to what extent, we don't know. But it is there. At the end of the day you are wrong on whether or not the Xbox One features heterogeneous unified memory architecture. It does.

He didn't say it was a complication, he said it would make development more complicated then said that is why we went with a unified system architecture. That means the two are seperate.
Again you are quoting MS talking heads instead of doing research. Of course MS is going to say we have that too. They obviously have no qualms blatantly lying to the public.
The One doesn't and can't have hUMA. Sorry to burstyour bubble.
I seriously wish there were more tech heads on here to let these people know whats up. I'm not a tech head, but I at least do reasearch so I'm not pulling shit out of my ass or repeating corporate lies.

You are just so completely wrong... You will never learn. And for all your fake "research" you keep claiming to do, you will never accept the countless data we show you that completely refutes your "I do my own magical fake make believe unicorn research and it says PS4 is dah betterz! YAR!"...
Seriously, you need to give this a rest.
You refer to tech heads, I am one of those. I am not as advanced as someone on here that claimed to be a silicon engineer or whatnot, but I do have my bachelor's in computer science which required many courses on hardware architecture and obviously a ton of programming classes from Java to C++ to Assembly. I have built OS's and emulators of microprocessors....

Sorry you're wrong. Everything, every single link you posted is completely unreliable on its own. You post two links from MS employees and a page from Wikepedia that does absolutely nothing to further your cause. Like I said all you are doing is repeating talking heads. You don't seem to even understand what that that wiki article debunks your argument.....if you did some research on the memory in the One. Some of it is I/O coherent according to MS themselves.
If you would do some research, like I have done, then you understand the difference between the two sytems. I shouldn't have to hold your hand and post links and tell you where to go. You should find stuff out for yourself. That also means you can't take one source at face value. You have to check it against other sources. You are using MS as your only source.
I also really don't understand why you believe so whole-heartedly in the word of a company that has been blatantly lying about the One since it's reveal.
