Specifications on five of AMD's next generation GPUs have been made public and the figures looks interesting. The details on the R9 290X and 290 are still under NDAs, but I will keep you informed as soon as they are revealed. The cards in question are the R9 280X, R9 270X, R7 260X, R7 250, and R7 240. All of these cards use PCI-Express 3.0, and support DirectX 11.2, OpenGL 4.3, and Mantle. These cards look like they might give NVIDIA some restless nights, and the top tier cards still have to be revealed. Below is a table with what is currently known about the cards.
