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. 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 Vsynch and screen refresh are not limiting performance.

The iPad 2 delivers a punch in the GLBenchmark Fill test. However, the (very distant) second-best score belongs to the Galaxy Tab 7.0 Plus, edging out the Transformer Prime by a step or two. It’s a different story in the GLBenchmark Egypt test, though; the Transformer Prime and iPad 2 are clearly tops in this test, although the Galaxy Tab 7.0 Plus scored better than the rest of the field.

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.
This is an Android-only benchmark, so unfortunately the iPad 2 couldn't play here. We'll also note that the Emperer's New Clothes test seems to be limited by screen refresh (Vsynch) on the higher-end devices, which is why the bar graph is close to flat on that test. However, looking at the more demanding Flower Power and Magic Island tests, we see some differences.
Fill rate seems to be the Galaxy Tab 7.0 Plus’ wheelhouse, as it once again spanked the competition, this time in the Flower Power test. On Magic Island, where Tegra 3 apparently dominates, the Galaxy Tab 7.0 Plus’ score was the worst of the bunch.
