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.
Dropping in at around 10 per cent slower than an HD 5670 but comfortably faster than the NVIDIA competition, the Sapphire card does well at its Ā£55 price point.
