i think they will have a decent 40nm gpu sometime H1 2011. i think they might announce something at GTC which is in a few weeks. this would make sense because it complies with the rumors that nvidia is ordering less 40nm lots.Quote:

I believe the die size is ~66.5mm2.Quote:

Maybe, I think they need to sort out their performance per mm2 before they stand a chance at a comeback.Quote:

Well. If all what our Mr.Salt says is true I hope AMD has some surprises for SI as well and won't just deliver a "simple" shrink. But seeing what they did lately, I'm a tiny tad optimistic.
I don't know. Maybe Big Green should have two teams working on different chips, one chip for HPC/GPGPU and one for gaming only. Thing is we only see the gaming side of the end.Quote:

nvidia has a lot more information to base their decisions off of than we do. i'm going for #2.
or kind of like your excellent sarcasm.:rolleyes: aside from that you misinterpreted my post. by 32nm node rumors i meant all of the godly things ATi would have done on 32nm if it werent for tsmc's incompetence. it's really poor journalism. ATi, the underdog, is going against the system which is holding them down. (i.e. nvidia and tsmc.)Quote:

also fermi's yields do not mean anything at all for other chips. they could have poorly designed the chip. when you have billions of transistors things get complicated. yields are no exception.
Take a literary course if you can't read.Quote:

Re-branding unreleased parts isn't in any fashion redundant.
Reading other rumours I don't think the 5770 will be renamed to the 6770, I think the 6770 will have the same architectural changes the 6870 will enjoy on a smaller scale and will become the 6950 in x2 form, while the 6970x2 will be the full blown 6870 dual we'd be expecting from AMD.
I do think the 5770 might be tweaked and re-branded but as a much lower model.
Going back to this:
These would have to be price brackets, and the only way it would be worth making the 6950 sell for less than the 5970 would be if they used smaller chips to start with. A chopped chip wouldn't use enough less current for it to be worth the effort.Quote:

The point that is making me think this was is the rumour that AMD is launching the 6770 first and not the 6870, not even nvidia would launch a new generation of GPU's with a re-branded unit. I guess we'll find out if AMD starts dumping the price on the 5770 or leaves the price high in order to protect stock of the silicon they plan to re-brand.
I hope they dont rebrand i mean 6990 = dual gpu and 6970 = single gpu does not compute that is if 6990 is made of 2 cayman chips bu if its made up of 2 Barts then i think its ok.
"first to market are Barts Pro and XT in october"Quote:

According to sweclockers that's correct. http://translate.google.com/translat...el-med-cypressQuote:

I'll just float this idea, I'm thinking if those benchmarks were real, they can only be from the Barts XT, it's the only chip that could match the GPUID profile we're seeing. If you look at the difference between the 3870 and the 4870 it would be possible for ATI to do this again. Especially if they planned to take their time with 6870.Quote:

Sure it'll decimate their top end prices but they can just release the aforementioned 6950. They'll keep the 6870 name back for either a push into a big core in 2011 or 28nm depending on how nvidia react.
If it works as planned, ATI would have the DX11 market sewn up by the time nvidia can release on 28nm and still make a profit as they've already proved they don't have to drop prices in comparison to nvidia.
This is all theory, but the rumours I've read up until this point support it.

I'm not sure if it's real,I can't find the source of this pic.
Hmmm, Geforce 9x00 series a new generation?Quote:

I still find it hard to believe that whipping up a frankenstein is easier then modifying an existing generation or un-shrinking a future one.
Whatever the case is, it sounds like AMD did the exact opposite of "not have a backup plan".
If they are going to rename some old cards or change the naming scheme, I can't really support that. It makes sense the way it is now. Don't try and confuse customers AMD.
i think this is real, if you check the other picture, this side is the same than the other one, and the 8 pins is left too.Quote:
