The OpenGL Speed & Performance-Per-Watt From The Radeon RX 480 To Radeon HD 4850/4870

The Tesseract results are quite interesting while the R9 285 had failed to run this benchmark for unknown reasons.

Furmark scaled nicely with all of the GPUs tested...

For this very stressful OpenGL benchmark, the performance-per-Watt under Furmark had improved by 6.6x for the span of GPUs covered.

The triangle benchmark in GpuTest mostly comes down to measuring vRAM performance and was also another nice indicator of how AMD GPUs have evolved since 2008.
