Default 8xxx speculation thread.

With AMD's 7xxx graphics cards launching in the next few months and it's Graphics Core Next coming into (pre)view, time seems about right to start up an 8xxx thread.

WIth the 7xxx series in 2011 getting AMD genned in on the 28nm node, seems logical the next step is a GCN cored 8xxx on 28nm for 2012?

Pretty early for 8xxx speculation. I think a big question is if AMD has an upgraded 7xxx series coming out with Kepler on the higher power TMSC process.

7xxx = optimized die shrink of 6xxx, basically what 6xxx was intended to be. They're not going to implement a whole new architecture and a new manufacturing node in the same generation, it would be too much risk. 8xxx series will probably be the new architecture better suited to GPGPU, similar to Nvidia's Fermi chips but hopefully not so hot and loud.

You are incorrect. http://www.pcper.com/reviews/Graphic...PUs-and-Beyond

I'll go with Anandtech on this one. Don't see AMD going with a completely new core on their 2011 28nm GPU's when they have so much experience putting their VLIW based architecture on silicon.

And Josh Walrath, as anyone who catches the PC Perspective podcast on TwiT knows, really REALLY likes his alcohol.

Ok ... guess we agree to disagree ... Yes, AMD could do a split launch but there has been speculation that there is the capability to do a cross architecture crossfire. The only VLIW4 gpu AMD would need is a low end one for Trinity.

Isn't the split launch of NI caused by the cancellation of TSMC 32nm Bulk Process instead of the product strategy of AMD themselves?
Northern Islands was supposed to be a VLIW-4 family on 32nm (top-to-bottom).

Eric Demers and Rick Bergman confirmed that GCN will launch this year (Q4 2011, but I believe it will be released in september or early october). There're multiple accounts of it circling, one can be found here: http://www.rage3d.com/interviews/amd.../index.php?p=4

This time it will be 28 nm top-to-bottom refresh. If there isn't issues like they have met with TSMC 40 nm (40G), then they probably won't need another RV740 chip...

Of course, NVIDIA says otherwise, claiming it's still as leaky as hell...

For Radeon HD 8xxx, don't expect massive scale-up as it would still be made on 28 nm (with estimated launch date: H2 2013), but it probably would include newer API support (if there are any ), and probably improved features.

What 'bout the last info that Haswell will have a DX11.1 compatible GPU?

http://www.donanimhaber.com/islemci/...GPU-olacak.htm

HD8000 will be DX11.1 as well, if that leak is true.
