Performance: Graphics and General System Level

An3DBench XL is a benchmarking tool based on an Android port of the jPCT 3D engine.

 

Graphics Testing
3D Graphics Testing

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 Emporer'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.  The Flower Power test shows the Galaxy Tab 7 Plus' slight fill rate advantage again, like it did in the GLBenchmark Fill test.  That said, the new T33 variant of Tegra 3 once again closes that gap significantly. 

On the other hand, our Magic Island numbers show a sizable lead for Tegra 3 all around and even more of an edge for the Pad Infinity, where the high polygon counts in this test shows a nice performance advantage for NVIDIA's Tegra 3 T33 new chip.

AnTuTu Android Benchmark
Subsystem level performance measurements

The Android-based AnTuTu benchmark does a nice job of measuring individual subsystem level performance for our tablet competitors here, with models for CPU, GPU, RAM and IO (or storage subsystem) performance.

Here we only had datapoints between the two most recent Asus Transformer tablets, the Prime and the Pad Infinity.  As you can see, in all tests the new T33 version of Tegra 3 offers a dramatic performance increase over the standard Tegra 3 bin, with the exception of GPU.  We're not sure why this was the case, but as you can see, the results scaled properly with a slide increase for the Pad Infinity in Performance mode.  Likely this is about an NVIDIA or Android driver-level optimization for the sort of workloads placed on the GPU core.  Finally, note the significant edge the Pad Infinity has in the IO test.  Apparently Asus has tweaked performance here as well, and it's likely at least partially attributed to the faster DDR3-1600 memory in the Pad Infinity, assisting with overall system throughput.
