3DMark 11 is a synthetic benchmark designed to test a GPU's performance at various aspects of DirectX 11 such as tessellation and DirectCompute.
As expected, both cards showed marginal improvement on the reference design score, with Palit outperforming the reference design by just 1%, and ASUS edging slightly ahead with a 3% improvement.
To see how the cards performed on an actual game, we picked Crysis 3, the toughest game in our benchmark set due to its extreme amounts of tessellation, per-pixel per-object motion blur, Bokeh Depth of Field, displacement mapping, particle and volumetric lighting and fog shadows.
However, both custom cards scored only marginally better than the reference design on paper,and displayed no tangible differences in terms of actual gaming experience. We expect the rest of our gaming benchmarks to produce similar results.
For our overclocking efforts, we managed to raise the Palit GTX 650 Ti Boost to 1176MHz with memory raised to 6600MHz DDR, and the ASUS slightly higher to 1190MHz, with memory to the same 6600MHz DDR. This resulted in a similar performance increase to the reference design, with both cards gaining about 10% at 3DMark's Performance preset and about 14% at the Extreme preset. Interestingly, the overclocking edge that the ASUS card has is almost in sync with its out-of-the-box performance that's about 3 to 5% ahead of the reference card.
