AMD Radeon R9 285 Review: Tonga and GCN Update 3.0

On paper, the new Tonga-based R9 285 looks to be slightly slower than the R9 280 it is intended to replace, but there's more than meets the eye.

Watch Dogs and Far Cry 3 Results

Now for Watch Dogs, and another sterling example of the Radeon R9 285 keeping up with the Radeon R9 280. There's not much else to say here except there are some significant frame time variance spikes across all cards, and this game isn't particularly smooth when travelling the highway at high speeds into new areas that probably cause a lot of map loading on-the-fly.

Finally, let's consider Far Cry 3. We suspect this game engine doesn't give the Radeon R9 285 a lot of room to make use of lossless color compression, as the Radeon R9 280 bests it here. That might make sense considering the detailed gradients on the lush foliage. Regardless, the Radeon R9 285 doesn't do badly here, either, tying with the GeForce GTX 760. As for frame time variance, this game displays spikes at various points in the game regardless of graphics hardware.
