It says HSA/hUMA confirmed for xbox one.

If Microsoft is using synchronized page tables, this strongly suggests that the Xbox One supports HSA/hUMA and that we were mistaken in our assertion to the contrary. Mea culpa.

hUMA is a "standard" if the xboxone does not , meet the requirements for hUMA it will not have hUMA, once again it is not confirmed to contain hUMA 

So you're saying they are wrong, it does not support HSA or hUMA. Or does it support HSA, and is it similar to hUMA? or is the article just damage control for their previous one?

This other says not.

In German (I need to use Google Translate).

What I'm getting is that Xbox One eSRAM is not into the shared memory system... so Xbox One did not support hUMA but if you look only to the DDR3 shared memory then they have something similar to hUMA.

So there are sites saying it is hUMA and others not because some consider the eSRAM part of the memory system and others not... in fact MS already said the eSRAM is not a cache like in Xbox 360... it is part of the memory system.

The xboxone does not meet the design standards required for hUMA. But in certain areas has some functionality "like" hUMA but it is not hUMA. The PS4's design does adhere to the design standards of which you would need to have hUMA. That's why the AMD manager even made the off the cuff pun that the PS4 contains a sense of hUMA.

Not to mention Sony is in the standards group for HSA. So it does make sense they would be adhereing to such design choices for the PS4 soc.

LOL at all the Expert techs at VGCHARTZ, why aren't you all Systems analysts? HIlarious.

OMG, we already went over this again no where has AMD stated that what Marc stated was not true again:

"AMD's Senior Product Marketing Manager Marc Diana said that the PS4 had shipped with a sense of Huma [Heterogeneous Uniform Memory Access] from AMD."

now again:

Earlier this morning AMD got in touch in with us and clarified Diana's statements. Here's what AMD had to say:

"During a recent gamescom 2013 interview, an AMD spokesperson made inaccurate statements regarding the details of our semi-custom APU architectures.   AMD will not comment on the Microsoft Xbox One and Sony PS4 memory architectures and will not speak for Microsoft, Sony or other AMD customers."

After sending some emails to our representatives at AMD I was told that "Kabini doesn't support hUMA" which is the APU that both the PS4 and Xbox One processors are based on.  AMD further clarified with us:

Our spokesperson made inaccurate statements about our semi-custom APU architectures and does not speak for Microsoft, Sony or the AMD semi-custom business unit responsible for co-developing the next generation console APUs.

again, no where does that say there was a conformation by AMD that the PS4 does not contain hUMA. read it more closely:

A:

their AMD source: 

"After sending some emails to our representatives at AMD"

so who is the rep, over @ AMD what's their name? 

unlike these other news outlets , the interview with Hise named the AMD rep! 

and once again just because the SOC's are based on Kabini does not mean outright that they are exactly like the PC desktop, they are custom tweaked.

and an xboxone developer already stated after this news broke that the xboxone has somthing "like" or  "similar" to hUMA which means its not hUMA! there is a reason it does not have it, and the PS4 does.

Again:

PlayStation 4 includes hUMA technology
