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.
The two GL Benchmark graphics tests we ran also paint the Samsung Galaxy Note 10.1 in a favorable light. In the Egypt Off-Screen test, the Galaxy Note 10.1 pulled ahead of every other tablet we've tested. In the fillrate test, the Galaxy Note 10.1 also performed very well, besting all of the Tegra 3-based devices and trailing only the Apple iPad 2.
