AMD Radeon HD 7790 Duel - ASUS vs Sapphire

3DMark 11 & 3DMark (2013)

3DMark 11 Results

As always, we start with 3DMark 11, our trusty synthetic benchmark designed to test a GPU's performance at various aspects of DirectX 11 such as tessellation and DirectCompute. The HD 7790 was fairly impressive here, performing much closer to the HD 7850 and GTX 660 side of things, trailing behind the 7850 by just 4% at the Performance preset and 7% at the Extreme preset. Meanwhile, it outscored the HD 7770 by a huge 43% at Performance and 35% at Extreme.


3DMark (2013) Results

3DMark (2013)'s Fire Strike benchmark is Futuremark's most ambitious and technical benchmark to date utilizing a grueling two-part test with extreme levels of tessellation and volumetric illumination, as well as complex smoke simulation using compute shaders and dynamic particle illumination, while Fire Strike Extreme ramps up the difficulty with more tessellation, more particle effects and more taxing DirectCompute calculations.

The HD 7790 struggled a little bit here, falling behind the HD 7850 by about 13% on Fire Strike, although it still outperformed the HD 7770 by 34%. 

On Fire Strike Extreme, it wasn't able to keep up with the HD 7850, trailing by 60%. We suspect this is due to it having only 1GB VRAM, compared to the HD 7850 and GTX 660's 2GB.
