ARM Cortex-A15 vs. NVIDIA Tegra 3 vs. Intel x86

Last week I shared some early benchmarks of the Samsung Chromebook while running Ubuntu Linux. The Samsung Chromebook is very interesting since it's one of the few readily available computers on the market employing an ARM Cortex-A15 processor rather than Cortex-A9 or other models. The Cortex-A15 found in the Samsung Exynos 5 Dual SoC proved to be very powerful and this Chromebook was quite a good deal with it being trivial to load Ubuntu Linux (and other distributions) while costing only $250 USD for this ARM-based laptop. In the past week I have carried out additional ARM Cortex-A15 benchmarks, including a comparison of its performance the the NVIDIA Tegra 3 quad-core ARM "Cardhu" tablet and several Intel Atom/Core x86 systems.

Intel Ivy Bridge On Linux Two-Month Redux

It has been 66 days since Intel formally introduced their Ivy Bridge processors as the 2012 successor to Sandy Bridge. My views on Intel Ivy Bridge (specifically the Core i7 3770K model) back on launch-day were very positive in terms of the Linux compatibility, CPU performance, and the HD 4000 graphics capabilities. Since then I've conducted dozens of additional tests looking at the Core i7 Ivy Bridge on Linux in different areas from comparative benchmarks to Microsoft Windows, trying to run BSD operating systems on the latest hardware, looking at the virtualization performance, compiler tuning, etc. Here is a recap of this additional Ivy Bridge testing that has happened over the past two months of near constant benchmarking.
