MojoKid writes "AMD has just announced a full suite of new GPUs based on its Graphics Core Next (GCN) architecture. The Radeon R5, R7, and R9 families are the new product lines aimed at mainstream, performance, and high-end gaming, respectively. Specs on the new cards are still limited, but we know that the highest-end R9 290X is a six-billion transistor GPU with more than 300GB/s of memory bandwidth and prominent support for 4K gaming. The R5 series will start at $89, with 1GB of RAM. The R7 260X will hit $139 with 2GB of RAM, the R9 270X and 280X appear to replace the current Radeon 7950 and 7970 with price points at $199 and $299, and 2GB/3GB of RAM, and then the R9 290X, at an unannounced price point and 4GB of RAM. AMD is also offering a limited preorder pack, that offers Battlefield 4 license combined with the graphics cards, which should go on sale in the very near future. Finally, AMD is also debuting a new positional and 3D spatial audio engine in conjunction with GenAudio dubbed 'AstoundSound,' but they're only making it available on the R9 290X, R9 280X, and the R9 270X."
