GLBenchmark is an OpenGL ES 2.0 benchmark with a myriad of test options available. 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.
In the Egypt Off Screen test, the One earned second place, coming in four frames per second behind Samsung’s Galaxy S 4. In the Fillrate test, the One performed better than any other Android smartphone we’ve tested to date but it still comes in behind Apple’s iPhone 5.
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.
The HTC One scores exceptionally well in the Ninja’s Garden and Magic Island tests, earning the top spot. It doesn’t fare quite as good in the Flower Power test, but still earns sixth place.
