RRA certifications are one of the most surefire methods of predicting when a particular GPU is going to come out and it looks like AMD is preparing a launch pretty soon because a big family of GPUs just passed RRA certification. While we cannot be sure this is indeed Big Navi, word on the rumor mill would point that way. If nothing else, gamers can expect some new GPUs to launch within a few months from AMD.

The RRA certification is something all consumer ASICs have to go through in South Korea - just like in the US. Unlike the States, however, RRA publishes its certifications in the public domain, which is great for us because it allows us to sniff out interesting new GPUs that are in the official pipeline. The AMD ATI-102-D32310 GPU received its RRA certification yesterday, meaning AMD has not only finalized its plans for the upcoming GPU family but submitted it to the authorities as well (no more changes in design are now possible).
