AMD Radeon RX 480 CrossFire Performance Comparison

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.

AMD Radeon RX 480 CrossFire Performance Comparison

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.

That was later clarified by Robert Hallock as a CPU-limited result. He also revealed that two Radeon RX 480 cards will deliver 83% better performance than a single Radeon RX 480 card.

Today, we are going to check out those claims in a variety of benchmarks and games. Let’s get down to it!

Benchmarking Notes

Our graphics benchmarking test bed has the following specifications :

Operating SystemMicrosoft Windows 10 64-bit

ProcessorIntel Core i7 6700K processor running at 4.0 GHz

MotherboardASRock Z170 Extreme4

Memory8 GB DDR4-2133 memory (dual-channel)

Storage240 GB HyperX Savage SSD

MonitorDell P2415Q Ultra HD Monitor

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.

      You are correct. It has 8 GB effective even though the specs are correct that it has 16 GB physical memory. We will add “8 GB effective” to be more accurate. Thanks for the comment!
