Benchmark: 3DMark 11
3DMark 11 is the latest version of this hugely-popular synthetic benchmark. Making use of DX11 features such as tessellation, compute shaders and multi-threading, it provides modern-day results and is available as a free download.
3DMark 11 gets us off and running and it shows that PowerColor's card has the ability to scale well. Having both Tahiti XT GPUs working in tandem makes this the fastest single Radeon graphics card we've ever tested.
Though, the immense scores aren't quite enough to catch the venerable GeForce GTX 690. The Devil 13 gets close when run using the built-in turbo BIOS, but you don't get any prizes for finishing second in this race.
