AMD Radeon RX 590 Linux Benchmarks, 18-Way NVIDIA/AMD Gaming Comparison

Next up is a look at the performance-per-Watt generated by the Phoronix Test Suite based upon its real-time polling of the AC system power consumption (interfacing with a WattsUp Pro power meter) for each of the game tests.

The Radeon RX 590 delivered around 14% higher performance than the RX 580, but it also consumes more power even with being a 12nm Polaris graphics card. For most games the RX 590 maintains comparable power efficiency to the RX 580 and even the original RX 480 Polaris.

The performance-per-Watt on the Radeon side remains a great deal behind NVIDIA's Turing and even Pascal graphics cards. The Radeon RX 590 power efficiency was just competing with the GTX 900 Maxwell cards.
