3DMark 2013 & Unigine 4.0 "Heaven"
3DMark 2013 Results
3DMark 2013 has two tests; Fire Strike and Fire Strike Extreme that put the graphics cards through their paces with extreme levels of tessellation and volumetric illumination, as well as complex smoke simulation using compute shaders and dynamic particle illumination. Fire Strike is meant for enthusiast-level graphics cards and dual-GPU setups; while Fire Strike Extreme increases the difficulty with more tessellation, more particle effects and more taxing DirectCompute calculations.
It is evident the NVIDIA GeForce GTX 750 Ti is trailing behind the GeForce GTX 760 and the competing AMD R9 270X and 270 cards by about 30- to 44% for this benchmark. This is to be expected because between this newcomer and the GeForce GTX 760, there's a couple of GTX 660 SKUs that fill in the gap.
Update: From the updated graph with a larger comparison sample, we can see that the new GeForce GTX 750 Ti is sandwiched between the GTX 650 Ti and the GTX 660 graphics cards, at least from a performance point of view. According to our scores, the performance of the GTX 750 Ti is about 15% slower than the GTX 660, while the GTX 650 Ti was found trailing behind a fair bit.
Unigine 4.0 "Heaven" Results
The Unigine 4.0 "Heaven" benchmark involves extreme amounts of tessellation and real-time global illumination to tax the GPU. The GPU is also tested with its dynamic sky with volumetric clouds, and screen-space ambient occlusion, among others. The new, first generation Maxwell chip continued to be outperformed by the other more recent generation graphics cards. However, the difference between the GTX 750 Ti and the Radeon R9 270 without antialiasing is minimal and that's heartening to note.
Update: The performance standings of the newcomer against the GeForce GTX 650 Ti and GTX 660 are somewhat similar to our findings from 3DMark above.
