Using the crazy quality settings at 1080p we find that the R9 390 is a whopping 24% faster than the GTX 970 when comparing the results from the normal test. By adding the R9 390 to the GTX 970 the average frame rate hit 51.5fps, a 65% performance boost which is quite impressive. However, R9 390 owners who add a GTX 970 to their system stand to gain just 56% additional performance, but the average frame rate will hit 60fps. Moreover, if the R9 390 is used as the primary display adapter in the 390/970 combo there is 17% more performance to be had.
Here we see that the R9 390X is 16% faster than the GTX 980 at 1080p. Combining the two with the GTX 980 as the primary card we received 50% more performance than a single GTX 980 and just 29% more performance than a single R9 390X. Swapping the cards around and placing the R9 390X in charge boosted the average frame rate to 63.7fps, which was 48% faster than a single R9 390X and 72% faster than the GTX 980. That’s not bad scaling performance, well at least it didn’t look bad until we threw in two 390X cards. Although CrossFire wasn’t enabled we labelled this as a CrossFire setup anyway, as it was two identical cards. Two R9 390X cards averaged 74.6fps making them 73% faster than a single R9 390X and 17% faster than the R9 390X/GTX 980 mixed combo.
Finally we have the big boys, the GTX 980 Ti and the Fury X. The 980 Ti was made to look slow sitting next to the Fury X, which was 22% faster. That is a massive win for the Fury X, a graphics card that is typically a little bit slower than the 980 Ti in DX11 titles. Combining the two produced an impressive 78fps with the GTX 980 Ti as the primary card and an even better 84fps with the Fury X positioned as the primary display adapter. This meant that the Fury/980 Ti combo was 59% faster than a single Fury X.
