You have seen our Radeon RX 480 review, so today, we are going to take a look at its CrossFire performance. For the uninitiated, that’s two Radeon RX 480 graphics cards running together.
You may recall that when Chief Architect of the Radeon Technologies Group, Raja Koduri, first revealed the Radeon RX 480, he made a startling claim that two Radeon RX 480 cards only utilized 51% of their processing capabilities to beat the GeForce GTX 1080 graphics card.
Today, we are going to check out those claims in a variety of benchmarks and games. Let’s get down to it!

Our graphics benchmarking test bed has the following specifications :
We used the GeForce driver version 372.54 for all three NVIDIA graphics cards used in our tests.
We used the Radeon Software 16.8.2 driver for the AMD graphics cards used in our tests. In addition, we enabled the Compatibility Mode for the Radeon RX 480 cards to ensure that they keep to their rated 150 W TDP.
