3DMark
3DMark 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.
PowerColor's mild core and memory overclocks are evident from the get-go, with performance in the synthetic 3DMark benchmark jumping by a couple of per cent. This small increase is enough to get the AMD-flavoured card ahead of Nvidia's stock-clocked GeForce GTX 760.
