AMD Radeon R9 and R7 Series General Overview

"  AMD today launched the AMD Radeon R7 240, R7 250, R7 260X, R9 270X, and the R9 280X desktop graphics cards. This shouldn’t come as a shock to any of our readers as we told you all about the cards during the AMD GPU14 Tech Day last month. We were able to give you the price points and names of the cards, but were unable to give you the exact specifications for each model. That is no longer the case as the embargo has lifted and the details are no longer a secret.  "
