AMD Radeon R9 290 On Linux
Now on to some Unigine Valley numbers...
The Radeon R9 290 is running extremely hot with an average temperature reported by the driver of 93 Celsius.
Unigine Valley pushes the graphics cards less hard than Furmark but the system power consumption was still much higher than the rest of the competition.
The GeForce GTX 680 edged out to have better performance-per-Watt over the R9 290.
