1) WiiU is a GPGPU.

2) I think youre reading into it too much as their stated reason were low yields... same thing the rumors state for why neXtBox is running into a little issues as well.

All signs for the last year of rumors have shown MSony going towards AMD APUs.

1. Where did I say it wasn't? My point about GPGPU is that it's completely impractical for game code.

2. I thought you were referring to AMD's delay of Kaveri. There's been no change to MS/Sony using AMD chips, and I did know about low yields on the 720 chip. It doesn't matter that MS/Sony are using them though, it won't affect AMD's impending bankruptcy.

1) you said the only GPGPU commercial product was in a video decoder. I said... its in WiiU too.

2) I don't remember the architecture/model name, just know it is related to the original plans for 2013 APUs.

Also, are current A10 APUs GPGPU tech inside? I thought it was but your posts make me question this.

 

EDIT: btw, AMD uses OpenCL (a GPGPU library) with its APU Fusion designs. Found this all over AMDs site.

Oh boy, I can't wait for Etho and others all of a sudden start praising how wonderful a GPGPU is and how it will change gaming after reading that thing while it didn't matter on the Wii U :P

As the article points out, the Wii U is capable of using GPGPU (this is a method of computing, not a specific type of GPU), but is doing it with "arguably weak chips."  If the GPU proves to be quite weak, then there isn't going to much of an advantage to using the GPU as a GPGPU.  The PS4 and NeXbox, if this rumor proves to be true, are going to be built with this method in mind, so should still come with very good CPUs and GPUs.

1) Commercial software products. As in, something that takes advantage of that GPGPU functionality. Hardware support means nothing without actual uses. For hardware, yes every PC graphics card since 2007 and all three next game consoles support it. However I expect exactly zero games will use it.

2) It's a seperate development branch. Plans for console APUs don't affect the delayed desktop products and vice versa.

3) Yes, because all AMD/Nvidia GPUs since 2007 are.

4) All you will find are tech demos and marketing presentations. No commercial products using OpenCL exist (other than the broken video decoder software I mentioned). They're basically lying about its usefulness.

Just how powerful do you think MS and Sony chips will be anyways? :P They will all be weak lol.

Way more powerful than a Wii U. That's really all we know.
Anything else is just wishful thinking on your part.

4-8x as powerful? The console as a whole is allowed to consume 6x as much power as Wii U.

Actualy you don't know that. Its just your wishful thinking.

HSA is a different beast - if they have it in next-gen consoles than some of this CPU ot GPGPU offloading talk might make sense. But, honestly, I don't see that happening.

out of curiousity, what do you mean by that? what would qualify as way more powerful?  how would you personally measure it?
