18-Way GPU Linux Benchmarks, Including The Radeon RX 460 & RX 470 On Open-Source

First up with the Xonotic result it shows that even with the Linux 4.8 kernel, the Radeon R9 290 is still affected by a serious performance regression. This R9 290 performance regression was introduced in the Linux 4.7 mainline kernel and has yet to be resolved. So take the current R9 290 results worth a grain of salt if using Linux 4.7~4.8, but hopefully its open-source performance will be fixed up in due time. With the PowerColor Radeon RX 460, its performance for Xonotic was around the same speed as the GTX 950. The PowerColor RX 460 is currently priced at $109 USD while the GTX 950 cards are $140~160, so this RX 460 on open-source may actually be nice for low-end gamers, if these results keep up... With the RX 470 results, keep in mind the card used for testing (Sapphire Nitro+) was factory-overclocked and thus performs quite close to the RX 480 compared to RX 470 cards at reference speeds.

While in raw performance the RX 460 was competing with the GTX 950, in performance-per-Watt it was able to leap past the GTX 950 and all other tested Maxwell graphics cards. It will be interesting to see where the GeForce GTX 1050 fits in when released.

A look at the raw system power consumption data for those interested in the numbers on this first test.
