I think the performance hit of using Edge Detect AA compared to MSAA with a tessellated scene will be relatively lower than it has been with traditional fairly low-poly scenes.Sorry, I don't get it: What's your point?
In any case, it would be truly impressive if AMD launches a full DX11 lineup from top to bottom. But what does that say about RV740? Scrapped?

I know it's theo, one of the most unreliable "sources" for news, but does anyone have any tidbits on if he's in fact correct on this one?
I think the performance hit of using Edge Detect AA compared to MSAA with a tessellated scene will be relatively lower than it has been with traditional fairly low-poly scenes.
ATI Edge Detect AA mode does an edge-detect pass (should scale with resolution not triangle count) to find triangle edges where there is a high contrast change ie where jaggies are most noticeable.
It then focuses high AA application to the detected high-contrast edges.
It applies a lower AA level to the other triangle edges.
MSAA applies the same level of AA on all triangle edges so will scale by triangle count.
Also ATI historically has relatively few ROPs/RBEs compared with NV but AA performance is similar due to higher ATI clocks.
Rumors suggest that the mainstream/high end cards of the new generation will have 32/64 RBEs.
That's more like NV unit numbers but will presumably still be running at ATI's typically higher clock rates.
So if those rumors are true, these cards should be fillrate monsters = Lots of AA performance.
Chiphell's nApoleon confirms some DX11 event on the 24th of September in Beijing.
Justifies Theo's news post?
Maybe he went to Munich, too:

Amazingly, double the ALUs of GT200, with a texture rate that's basically unchanged. Woah, 6 multiprocessors per cluster.

Isn't he the guy who always claims to have an unreleased card/CPU, promises to benchmark it and then it turns out it's all bs?

Added some more info:
AMD cliamt Manhattan that better performance per watt and about 135 to 145% faster compared to the M9x series. 40nm, DX11 With Power Xpress, SG Switching, XGP support and pin to pin compatible with the M9x designs.

Now not only rumors of a full top to bottom Dx11 launch by AMD, but also a full top to bottom launch of Dx11 Mobile GPUs?
Yeah, this is starting to make me wonder if someone's been partaking of the crack pipe a little too much.
