Performance: Graphics GLBenchmark
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 Vsynch and screen refresh are not limiting performance.
Looking at the texture fill rate numbers, Apple's A5 offers a boatload of bandwidth, almost two times that of NVIDIA's new Tegra 3 T33 SoC in the Pad Infinity, even at its performance setting. Samsung's Exynos processor holds its own for that matter, in the Galaxy Tab 7 Plus. Regardless, Tegra 3, at least according to GLBenchmark, has roughly three times the texture fill rate of Tegra 2 and the T33 variant expands on that performance even more.
In the Egypt Off Screen test, the Asus Pad Infinity's Tegra 3 T33 begins to close in on the iPad 2's A5 processor and offers over a 20% performance boost versus the standard 1.3Ghz Tegra 3 SoC in the Transformer Prime or Pad 300.
