First of all, Skynner clarified that AMD will not target a $999 single GPU solution (like Nvidia) and will continue to address the ultra-enthusiast segment with a dual-GPU offering like the 7990.
He said that the next-generation line that will be unveiled at the event is targeting more of the enthusiast market versus the ultra-enthusiast one. AMD's next enthusiast GPU - already implied to be the launch vehicle for their forthcoming microarchitecture - will be a 28nm product.
"..At 28nm for an enthusiast GPU, we can achieve higher clock speeds and higher absolute performance," he said.
"It's also extremely efficient. [Nvidia's Kepler] GK110 is nearly 30% bigger from a die size point of view. We believe we have the best performance for the die size for the enthusiast GPU," Skynner added.
23% smaller than GK110 would put the die size of AMD?s future GPU at around 425mm2, making it slightly larger than Cayman.
