3DMark Ice Storm (2013)
Ice Storm is an OpenGL ES 2.0 benchmark consisting of two graphics tests rendered at 720p, designed to stress both the GPU and CPU (with the latter tested with physics). Ice Storm Extreme raises the rendering resolution to 1080p and uses higher quality textures and post-processing effects to create a more demanding load. Similar to the Quadrant benchmark scores, the Xperia Z Ultra led the competition by huge margins in 3DMark. As an example, the Xperia Z Ultra outscored the Optimus G Pro by almost double.
