[PCPer] Sony PlayStation 4 (PS4) will NOT utilize AMD hUMA with Kabini-based SoC

You might have seen some reports in the last couple of days claiming that the upcoming Sony PlayStation 4 (PS4) will have a big advantage over the Xbox One thanks to its unique ability to support AMD's hUMA memory architecture. hUMA, heterogeneous unified memory architecture, is an exciting new memory technology that AMD has built into upcoming APUs.

There's just one problems with these various reports (VR-Zone, ExtremeTech): they're wrong. 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.

PS4 APU is not kabini, not even close. Plus, this would contradict statements made by PS4 architect Mark Cerny.

You ask the right question, you (should) get the right answer. They asked the reps whether kabini supported hUMA and the answer was no (correct).

Company reps can sometimes be as clueless as members of the public, so it might not matter.

True, but they also said:
Quote:
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.

Who knows.

Regardless of whatever the truth is, internet has been salivating over huma enabled AMD chips (they'd never have heard of) for the past few days so its a win for AMD all round.

I have to question the reliability of sources that say things like this:
Quote:
I have had several people point out that it's possible Sony and Microsoft worked on their own custom memory architectures that will perform similar functionally to hUMA. That is entirely possible but means that official hUMA support isn't on the SoCs.

Huh?
