Lastly are numbers from the most demanding benchmark ran for this article: Unigine Heaven.

The HD 4870 was hanging when running this benchmark. The HD 4850 results indicate a higher FPS than the other older GPUs since it failed to handle the OpenGL tessellation code path. But even with noting these differences, Heaven shows quite the performance difference for the range of AMD GPUs benchmarked on Linux 4.7 with Mesa 12.1-devel.

The performance-per-Watt has improved sharply with the RX 480 compared to past generations of AMD graphics processors.

There's a look at the GPU core temperatures that were recorded during the benchmarking process... The RX 480 ended up falling right in the middle for the average temperature. Note that some of these cards were reference models with coolers as well designed as some of the after-market cards. Through these benchmarks run, the Radeon RX 480 had an average temperature of 59C with a peak of 80 degrees.

Finally is a look at the overall AC system power consumption data for the duration of all the OpenGL benchmarks used for this article.

That's the latest round of Radeon RX 480 Linux data I have ready at this time. Hopefully you found this OpenGL data and performance-per-Watt metrics for the wide-range of AMD GPUs interesting.
