We are comparing the percentage increase from GTX 980 to GTX 980 SLI and then from R9 390X to R9 390X CrossFire.
Adding a second GeForce GTX 980 improves performance by 83.4%. That means we are seeing scaling efficiency of 83.4% out of GTX 980 SLI.
Adding a second Radeon R9 390X improves performance by 99.7%. That means we are seeing scaling efficiency of 99.7% out of R9 390X CrossFire.
We checked and re-tested this test three times after we saw that kind of scaling out of R9 390X CrossFire. Every run was consistent and every time this is the kind of scaling we experienced out of R9 390X CrossFire. This is by far the best and highest scaling efficiency we've ever come across for any video card in any game. This kind of scaling is what allows the R9 390X CrossFire to compete well at 4K with the competition. We aren't sure if the reason for this is due to the doubled 8GB of VRAM, or what, but it is what it is and it is incredible.
People will swear the 970 and 980 are better for Tomb Raider. Same will likely happen with the division.
