Overwatch, Rainbow Six Siege, Resident Evil 7
Ryzen is rather competitive in Overwatch at 1080p and in fact does much better with the GTX 1080 than it does Vega 64, which is something we've seen in other DX11 titles. Moving to 1440p the margins close up as the game becomes primarily GPU bound and here the R5 1600 delivers the exact same experience as the 7700K.
We again see more competitive results from the Ryzen CPU, this time when testing with Rainbow Six Siege. That said, at 1080p the 7700K is really able to turn Vega 64 on and get the most out of AMD's high-end GPU, pushing 193 fps on average with an impressive 155 fps for the 1% low result. The GTX 1080 though delivers similar results on both CPUs.
As we move to 1440p the gap closes even more and here the 7700K is only a fraction faster than the R5 1600 while Vega 64 offers slightly better performance than the GTX 1080.
The numbers seen when testing with Resident Evil 7 are similar to those we just saw in Rainbow Six Siege. The Ryzen 5 1600 is again competitive with the 7700K while Vega 64 is able to comfortably edge out the GTX 1080. Of course the Vega graphics card does cost more so this isn't a huge win for AMD, I'm merely noting the margins.
