AMD Shows Off The Radeon HD 7990
 

Although no concrete specs were given, AMD did show off its upcoming Radeon HD 7990 at GDC. There isn't much info at this time other than what you see in the image below and this comment from the general manager of AMD's graphics business unit: "We're not saying much about it other than it's two series-7900 GPUs on a single card, and it's whisper quiet."
