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.
AMD GPUs tend to do well in the synthetic test, better than real-world gaming performance would suggest. Anyway, the Sapphire HD 7790 is around 25 per cent faster than the GTX 650 Ti in the Fire Strike benchmark. Even a stock-clocked card would be considerably faster than the GTX 650 Ti.
