Obviously, ASIC's are design to be single application efficient. GPU's primary intent is to game, graphic content creation(ie Photoshop, Premiere, etc.), 3D modeling and play HD content.
Oh right, and that's why no one bothered to mine with GPUs, ever. And any technology that would further improve on existing GPU tech would certainly have absolutely no impact on mining as it exists today. Or...monkeys might fly out my butt.
The battle for scrypt is over.
This. ASICs are going to rape it. Now, X11 and scrypt-N coins may see a benefit from new GPU technologies.
