Sad part is be prepared for $650 AMD Radeon 9970 ........
I don't think it will be 20nm card , most likely a re-spin of current chips with some improvements.
No, it will definitely be 20nm. Whether or not it beats the GTX780 depends on how big they intend to make the chip. If they keep the die size roughly the same as the 7970 it will probably meet or slightly beat the GTX 780 but should do so at a greatly reduced price.
How do we know this? Well 20nm production begins Q3 2013. That is this fall. According to TSMC:
"TSMC's 20nm process technology can provide 30 percent higher speed, 1.9 times the density, or 25 percent less power than its 28nm technology."
So you can see they either increase clock speeds, run with less power, or greatly increase transistor density. My guess if they will focus on greatly increased transistor density and power savings. Then run a clock speed in the 800Mhz-1000Mhz range with either a 256-bit memory bus and 4GB of vram on the top end sku or 384-bit bus with 6GB of vram.
In any case they are going to be some really nice, powerful cards.EDIT:
I say it will definitely be on 20nm but there is a small chance it could still be 28nm. The evidence some might point at to back that up is AMD's CEO has said they will not be going to new nodes as aggressively as in the past, although he was talking about their CPUs at the time. Also new nodes are getting more and more expensive. The reason I think they will go to 20nm is that they just can't take that top spot without either making the die really large, which is also very expensive even on an already proven node like 28nm, or they have to find a lot
of extra efficiency in design. I think they have to go 20nm or give up the performance crown and I don't think they are ready to give up the performance crown.Edited by Mygaffer - 7/9/13 at 1:04pm
