Performance Testing – CPU Performance

Linpack

Note: this benchmarking section is currently experimental and constantly being tweaked to better reflect actual performance of these devices. In order to compare the performance of phones with similar clockspeeds, but different mobile architectures and operating systems, we have come up with this new experimental mobile device performance testing.

For this test, we ran the mobile versions of Linpack, a popular tool for measuring Floating Point operations in supercomputers. We ran Linpack on a variety of our personal devices.

In this benchmark, we are a bit disappointed by the performance of the Nexus S 4g. While it utilizes a Qualcomm Snapdragon platform, like the Evo 4G and Droid Incredible, the performance is lower. Likely, this is due to irregularities in the benchmarking application under Gingerbread.

Quadrant

Quadrant is an entire system performance mobile benchmarking
suite, which tests things like the CPU, Memory throughput, I/O access, as well as 2D and 3D graphics.

Once again, the the Quadrant tests, performance of the Nexus S 4G is lower than expected. While performance should be more inline with the Galaxy Tab and Droid Incredible, both of which are Snapdragon platforms, all 3 devices are outperformed by the TI OMAP3 (Droid X) and Tegra ARM platforms (Xoom)
