Conclusion

The A10-7878K had no trouble when running with a single R9 285. We threw in another R9 285 and ran a few benchmarks in Crossfire. Crossfire scaling has improved and come along way. The R9 285 doesn't make use of a Crossfire bridge connector. This made it even easier to set up. Expecting a quad core CPU not to bottleneck two middle to high end GPUs is certainly unrealistic. The reason we did give it a go was to see by how much it would hold back two GPUs, whether Crossfire was a viable option and worth the added expenditure. We couldn't compare the A10-7870K with the FX 8350 with dual GPUs as the motherboard we used for the FX 8350 sadly doesn't support Crossfire. So the results in this category will be a Single GPU vs Dual GPU set up, running at x8/x8 on the Gigabyte F2A88X-UP4 motherboard. Before we even look into the benchmark charts, we can confirm that while playing games both GPUs were not being maxed out with the A10-7870K. We did not face any stuttering issues and it appears that the improvements made to Crossfire are significant and have aided with reducing stutter in games. 

The settings used in each game while testing Crossfire was the same as those used while testing the A0-7870K and a single GPU.

The following games were used to test the gaming performance of the A10-7870K:

  • GTA V
  • The Witcher 3
  • Shadow of Mordor
  • Dirt 3
  • Metro Last Light Redux
  • Tomb Raider
  • Resident Evil 6 

 

 

 

 

 

 

 

 

The common trend throughout all the benchmarks charts reveal that adding a second GPU and running in Crossfire with the R9 285 does lead to a boost in performance. However, the increase in fps resulting from the addition of an extra GPU isn’t as much as one would expect. We can thus, conclude that the A10-7870K will hold back two R9 285's in Crossfire. Many may have already guessed the outcome since it is essentially a quad core CPU. The only game which used both GPUs at their maximum usage was Tomb Raider. These charts are basically to show the CPU potential of the A10-7870K and not to test Crossfire scaling. We believe that with a more powerful CPU like the FX 8350, we may see good scaling in other games and just not only Tomb Raider. Lacking an AM3+ motherboard we couldn’t put the FX 8350 to the test with the R9 285’s in Crossfire. We are looking to do another review of the R9 285’s in Crossfire with the FX 8350. That review will only be possible if AMD’s motherboard partners decide to help us out. We think that the R9 285 is still a very relevant card, given it’s architecture and the fact that the newly released R9 380 is a refresh of the R9 285.
