AMD Radeon R9 290 On Linux
 

All you alternative OS folks out there will definitely be interested in this review of the AMD Radeon R9 290 on Linux. AMD unveiled the Radeon R9 290 graphics card at the beginning of November as one step down from the new flagship Radeon R9 290X graphics card. Numerous Windows reviews praised the graphics card for its great performance, but what wasn't clear at the time was how the Linux performance and compatibility was for this new $399 USD graphics card. AMD hadn't offered any review samples to Phoronix for conducting any Linux-based testing and benchmarking, but it's more clear now why that didn't happen: the Linux performance isn't stellar.
