3DMark Sky Diver

Version and / or Patch Used: 1.1

Sky Diver really manages to make excellent use of the overclock here; as you see, the HIS R9 285 IceQ X2 2GB OC manages to outperform even the Sapphire R9 280X 3GB Vapor-X OC in this situation.

Catzilla

Version and / or Patch Used: 1.3

Looking at Catzilla performance, we again see the overclock we managed to achieve on the HIS R9 285 IceQ X2 2GB OC really helps separate the card form the R9 280 3GB and the R9 285 2GB. At the lower resolution 1920 x 1080 preset, you can see we almost manage to line up with the higher-end R9 280X 3GB Vapor-X OC.
