GLBenchmark is new to our 3D performance benchmark set. The test suite is an OpenGL ES 2.0 benchmark with a number of performance metrics incorporated in it. We specifically use the Fill Texture Fetch suite to measure raw texture fill rate of a graphics core and the Egypt Off Screen test to measure 3D performance in frames per second. The Off Screen test renders workloads at 1280x720 for all devices, but off-screen, so Vsync and screen refresh are not limiting performance.

There's no other tablet that can touch the iPad 2 in the GLBenchmark Fill test, that's just life. The Sony Tablet S does hold its own versus the other Tegra 2-based slates here and actually takes the lead position for its peer group.

An3DBench XL is a benchmarking tool based on an Android port of the jPCT 3D engine. The app runs 7 tests in total that look at graphics processor fill rate and complex rendering workloads and scenes.
Things pick up for the Tablet S in An3DBench XL, and while it doesn't keep pace with the Transformer Prime, it does run neck neck with the Galaxy Tab 10.1 and several other Tegra 2-based devices.
