The Radeon RX 480 CrossFire showed great promise in the 3DMark benchmarks. It was able to deliver 93% to 96% better performance than a single Radeon RX 480 graphics card.
The actual boost in frame rate was smaller, of course, due to CPU limits. But it proved to be faster than the GeForce GTX 1070 by 15% to 18% in DirectX 11, and 26% in DirectX 12. Very impressive.
Unfortunately, we do not have an NVIDIA GeForce GTX 1080 in our benchmark suite, but we know that it is roughly 20%-25% faster than the GeForce GTX 1070. So we can guesstimate that the Radeon RX 480 CrossFire will be slightly faster than the GeForce GTX 1080 in DirectX 12, and slightly slower in DirectX 11.
From a price-performance perspective, the Radeon RX 480 CrossFire ties with the GeForce GTX 1070, if we only take into account the 3DMark results. It loses out to the GeForce GTX 1070 when it comes to actual games, particularly in games that don’t work well or at all with CrossFire.
As you can tell from the table above, the reliability of the CrossFire mode is still quite iffy. That is really too bad, because the 3DMark results show that the Radeon RX 480 CrossFire has great potential, particularly in DirectX 12.
If AMD can get the CrossFire mode to work in all games, the Radeon RX 480 CrossFire is a great alternative to the GeForce GTX 1080. It offers equivalent performance at a 20% discount (US$478 vs. US$599), albeit with much higher power consumption (300W vs. 180W).
