My post...

http://gamrconnect.vgchartz.com/post.php?id=5603723

I tried to explained what is hUMA (I never coded to a CPU/GPU with hUMA because it is a new thing in the industry).

PS4 GPU does support hUMA at full state... MS did not support that because the eSRAM... the eSRAM is not coherent in Xbone and a hUMA enable system needs to have all shared coherent memory... so because the eSRAM MS was forced to create a new solution (based in hUMA? I don't know)... if that solution is better or not than hUMA I don't have the awnser because I don't even know if hUMA is that good but in terms of code you have a lot less to write with hUMA (better performance than a not shared memory? I think so).

To make the thinkgs simples the Xbone use a difference memory system from everyting I already saw...

Main DRAM pool: CPU/GPU shared memory coherence
eSRAM pool: CPU/CPU shared memory non-coherence

Xbone is a non-hUMA compilance... their solution is better than hUMA? I don't know.

Are there any other comments that you have issue in that thread?

About my graduations... I'm a low/high level software guy and not a hardware engineer but I wrote techinical articles about new hardware architectures years ago (expecificly Phenon, Core, Fermi, R600, R700, etc).

Just to add reability to my posts...

AMD said again what I said here... PS4 uses UMA and Xbone eSRAM (there are no UMA with non-coherence eSRAM).

And logically you can have hUMA without eSRAM being involved.

However, regardless there are two points to be made here.

First, Microsoft designed and fabricated their own silicon.  They purchased the rights to AMDs technology.  AMD doesn't know what Microsoft did or didn't do.

Second, your argument doesn't stand, anymore than any other assertion.  The Xbox One SoC includes coherency between the GPU and CPU.  It utilizes unified memory on the DDR3 memory, and it employes an hetrogenuous system architecture.  Not only that, but the Xbox One's SoC also includes coherency with the eSRAM.  So whether or not it uses "hUMA" it is, AS I stated, a hetrogenuous memory architecture.  As have many others in the professional community.

The argument against there being so, was largely based on the fact that some marketing guy from AMD said so.  Yet the fact remains that the core Jaguar technology included it, so in the very least, the CPU and GPU would have had hUMA on the DDR3 memory, and no on the eSRAM.  However, that isn't the case because Microsoft made the eSRAM coherent between the CPU and GPU. 

Finally, let's drop this conversation, it isn't germain to this thread.  I brought it up not because I wanted to discuss it here, but because while you stated your opinion in that thread, you along with a couple of other people (one joined in this thread) failed to actually look at what was being said and discreditted it out of hand, saying any opposition to it was wrong, despite the facts that proved otherwise. 

In the end, those, including myself, who were indeed right have the satisfaction of knowing we were indeed right, and knowing that whether you truly knew you were right or wrong didn't matter, but the fact that you were closed minded enough to join in the infantile conversation and not support the logical conclusions based on factual information.  Suggests that your arguments are slanted (e.g. biased). 

I personally don't care whether you support the PS4, the Xbox One, or the Wii U.  That isn't important to me.  What is important to me is, when you have the technological knowledge whether you offer an impartial opinion or argument.  Especially when it isn't something you want to do.
