AMD Mantle Driver to Only Benefit Four GPUs Initially
 

Crushed your F5 key on AMD driver download page yet? Unless you have four very specific AMD Radeon GPUs, you can stop it right now. According to DICE, developers of the first game to take advantage of Mantle, the 3D graphics API AMD is introducing with its Catalyst 14.1 beta driver, will give tangible benefits to only four specific GPUs - Radeon R9 290X, R9 290 (non-X), R7 260X, and A-Series "Kaveri" APU-integrated R7 200 series.

Owners of all other Radeon GPUs, including those based on the Graphics CoreNext (GCN) architecture, such as the recently launched R9 280X and R9 270X, are out of luck, for now. AMD is still ironing out issues with Mantle on those other GCN GPUs. Interestingly, in the same press note, DICE posted performance numbers yielded on an HD 7970, which look promising. AMD is expected to release its Catalyst 14.1 beta driver a little later this week, as it's jousting with some last-minute bug-finds.
