How The Radeon OpenGL Performance Has Evolved From The HD 2900XT To RX Vega

First up is the synthetic OpenGL 2.1 GLMark2 benchmark that can still show scaling up through the RX Vega 64. The RX Vega 64 comes up at 44x faster than the HD 2900XT in this synthetic test or 6.3x faster than the once-impressive Radeon HD 4890.

But the RX Vega 64 by far is the most power hungry graphics card tested... The average power draw of the RX Vega 64 is three times higher than the HD 2900XT.

When looking at the performance-per-Watt for GLMark2, the R9 Fury is the most efficient followed by the RX 480. The RX Vega 56 was behind the Polaris RX 480 and the RX Vega 64 was on the level of efficiency of the Radeon HD 7950 GCN 1.0 hardware.

Dota 2 could run on the hardware back to the Radeon HD 4870. Going from the Radeon HD 4870 to RX Vega 64 is nearly a 7x improvement in frame-rate.

But on a performance-per-Watt basis, the RX Vega 64 only does slightly better than the R9 290 while the RX 480 Polaris graphics card leads in this metric.
