maybe we'll see another 4770 type part (~$100) as AMD's first 32nm GPU, before Northern Islands. It would make sense based on precedent and what the Anandtech article said about AMD wanting to get process refinement before moving to the larger and more expensive dies.
Problem is, there is no 32nm for them to do as they did previously. I mean, there's 32nm processes out there, but where AMD has access to 32nm, they make thier cpus, and the cpus cannot afford to wait, as they are a bit supply constrained.
So now we are back full circle. Rumoured(although from questionable sources), was Southern Islands...a combination of the missing 32nm design, and current 40nm design. But noone's sure what combination that will be. Now these gpus are coming...
I said before I doubted there would be "refresh". Given the info that 4-series had specific issues with TSMC's process, and now, over time, issues remain @ TSMC, so this very much limits what combination AMD can come up with.
I will be very surprised if there is even cards in October...what might be happening is a launch to OEM partners...telling them that the gpu design is done, and that things like pcbs and boxes can be made. AMD will then be selling the gpus to OEMs...who then needs to re-ship to retailers....That leads to maybe December for cards....as I said much earlier.
It's possible that they could take this chip, near 5850 performance, put two on a pcb...and the 6-series cards are done.
The question that remains...how do they get that performance? Does a simple add-on of 160 shaders to 4890 give that? A few tweaks here and there...and those slides that were posted earlier showing shader changes, seem pretty fake to me.
