Benchmarking Ubuntu Linux On The Google Nexus 10
When starting with the Block Tridiagonal and Conjugate Gradient tests inside NASA's NAS Parallel Benchmarks suite, the Google Nexus 10 faired much better than the OMAP4 PandaBoard ES, NVIDIA Tegra 3 Cardhu, and Intel Atom 330 configurations. This really isn't to any surprise since the Cortex-A15 is much faster than the Cortex-A9, even when it comes to dual-core vs. quad-core for most workloads. It was a bit interesting though that the Series 5 Chromebook was slightly faster than the Nexus 10 when both devices are being powered by a Samsung Exynos 5 Dual SoC and other similar components. The Nexus 10 being a bit slower than the Chromebook may come down to the Nexus devices having the Android/CyanogenMod layer underneath where is the Chromebook started off as ChrUbuntu in a virgin Linux environment.
For the EP.B test the Cardhu and even Atom 330 faired better than the Exynos 5 hardware since EP is short for "Embarrassingly Parallel" where the more cores the merrier and thus the hardware with four cores easily does much better than the dual-core A15s.
The Lower-Upper symmetric Gauss-Seidel results are more of what's expected from this Ubuntu Linux performance comparison, aside from a bit of a surprise about Ubuntu Touch being slower than a clean Ubuntu environment.
