We put the cards through the grueling benchmarks of the 3DMark (2013) Fire Strike with extreme levels of tessellation and volumetric illumination, as well as complex smoke simulation using compute shaders and dynamic particle illumination. The Fire Strike Extreme tests will tax the cards further with more tessellation, more particle effects and more taxing DirectCompute calculations.
The MSI GeForce GTX 780 Twin Frozr VI Gaming is a clear winner against the ASUS card, due to its higher clock speed. As a single card, its gains over the ASUS GeForce GTX 780 DirectCU II OC are in the range of 3- to 3.2%. In the 2-way SLI configuration, the MSI cards' gains were in the range of 1.9- to 2.10 percent.
When the leading card was pitted against the Titan, for the Fire Strike test, the Titan pulled ahead by slightly over 6 percent, and in the 2-way SLI configuration, the Titans' gains were reduced to 3.82%. For the more demanding Fire Strike Extreme, its gains, when the cards were in SLI configuration, were pared to just 1.9 percent. As a single card, the Titan's gain was about 5.6 percent, which was somewhat in line when we last tested in an older article.
In order to gauge their in-game performance, we put the cards through the paces of Crysis 3. With its extreme amounts of tessellation, per-pixel per-object motion blur, Bokeh Depth of Field, displacement mapping, particle and volumetric lighting and fog shadows, this is graphically demanding benchmark.
In its 2-way SLI configuration, the ASUS GeForce GTX 780 cards pulled surprisingly pulled up ahead of the MSI GTX 780 and reference GTX Titan cards. At the resolution of 2560 x 1600 pixels, the ASUS cards managed to pull ahead of the Titans by just a hair! As single cards, the custom GTX 780s and the GTX Titan were almost running neck-to-neck at both resolutions.
