I'll just make a list to make the format easier.

These are just a few of the sites that refer to richland as an APU.  I'm not going to pretend I'm an expert on the subject, but I'm also not going to believe that you are.  I will however believe every website I've seen about Richland which refers to the line as APUs. You can tell me it's not, but I don't care unless you can show me a source that makes the same claim, because you don't get to decide on your own what is or is not an APU.  You're asserting that Richland is not an APU despite everyone else labeling it as such.  So, back up that assertion.

So far as I can tell, no APU that existed in 2013 meets your criteria for being an APU.  In which case, your claim that the PS4 is 12x more powerful or whatever is completely nonsensical.  What were you comparing the PS4 to?

2.  I don't care if you don't like extreme tech.  Look over the sites I gave you, the starred ones.  They will explain that the Kabani line uses Jaguar cores.  The PS4, as confirmed by Sony and AMD, also uses Jaguar cores.  As for Kaveri...

The Kaveri line uses Steamroller cores.  So, the PS4 is clearly based on Kabani and not Kaveri.  Incidentally, the Kabani line does not support HUMA.  It's possible that the ps4 has some customization to allow that but that isn't confirmed.

3.  Speaking of Kaveri, Kaveri utilizes HSA/HUMA

I doubt all of those websites are biased liars :).

So, even though you tried to alter your original claim, it's still dead wrong.  AMD uses both technologies.  The PS4 has not been confirmed to use HUMA.

While we're on the subject, according to AMD, the chip is all their intellectual property.

Everything that Sony has shared in that single chip is AMD [intellectual property], but we have not built an APU quite like that for anyone else in the market.

http://www.playstationlifestyle.net/2013/02/26/amd-talks-ps4-it-is-by-far-the-most-powerful-apu-we-have-built-to-date-we-have-not-built-an-apu-quite-like-that-for-anyone-else/

What does software support have to do with anything?  Your point was that the technologies were developed and owned by Sony and therefore were not able to be implemented in any AMD chips.  But, it absolutely is included in the Kaveri line.  Whether or not any computers can actually run it, AMD obviously has the rights to utilize it in their chips, which makes it unlikely that Sony spent 3 billion dollars developing tech they wouldn't fully own and have no real use for outside the PS4.

All that being said, Open CL is available on Linux and Windows, and allows usage of HSA/hUMA.


5.  If they were looking for sensationalism, wouldn't they claim that the Cell cost more than 400 million?  If it was 400 million, and you're saying billions, that is actually the opposite of sensationalism.  So, if you're saying the book is sensationalizing things, then the actual figure for cell development should be considerably less than that.

But hey, if you don't like my source for 400 million fine.  Why should I believe your figure with no evidence?

6.  Ummmmm... no... I wasn't the one who made the original assertion.  Look back two pages if you don't believe me.  I was responding to your assertions that the PS4 cost 6 billion to develop with 3 billion going to the processor.  

So since it's the job of the person who makes the assertion to verify them, please verify your assertions :).
