Benchmarking Ubuntu Linux On The Google Nexus 7
It shouldn't come as a surprise if you have followed the earlier benchmarks of the NVIDIA Cardhu developer tablet against the Samsung Series 5 Chromebook, since it's nearly the same as the Nexus 7 and Nexus 10 hardware specifications, respectively, but the Nexus 10 is much faster than the Nexus 7. There are some rare workloads where a quad-core Cortex-A9 (Tegra 3) can outperform a dual-core Cortex-A15 (Exynos 5 Dual), but for most tests the newer Samsung SoC reigns supreme. When the quad-core Cortex-A15s start emerging like the NVIDIA Tegra 4, the Cortex-A9s will suddenly look extremely weak.
The Google Nexus 7 tablet with Ubuntu Touch was generally slower than the NVIDIA developer/reference tablet with the same SoC, which may come down to the overhead of Ubuntu Touch and being based upon Android / CyanogenMod rather than a clean, virgin Linux installation.
If you wish to see how your x86 or ARM Linux system compares to these twelve unique Ubuntu Linux-powered systems in this article for a plethora of open-source benchmarks, it's as simple as installing the Phoronix Test Suite and running phoronix-test-suite benchmark 1303138-FO-UNEXUS3TE85. The Phoronix Test Suite automatically fetches all of these data points and specific version-controlled benchmarks from OpenBenchmarking.org followed by automatically installing the benchmarks with the same settings, running the benchmarks, and displaying the data in a very concise and effective way while all being fully automated and controlled for reproducibility.
For the many Phoronix readers that have been requesting benchmarks of Ubuntu on the Google Nexus 4, I agree with you, it would be very interesting. The Nexus 4 is powered by Qualcomm's Snapdragon S4 Pro processor, which would be interesting to see how it compares in these raw, computationally intense Linux benchmarks relative to these other ARM SoCs. For delivering these Nexus 7 and Nexus 10 benchmarks, I purchased the tablets retail, which would also have to be done for delivering Nexus 4 results.
