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.
Overall the performance out of the Samsung Exynos 5 Dual on the new Chromebook is very attractive. While Ubuntu on the Chromebook isn't perfect (the broken touchpad and sound support, etc), for those looking towards the ARM Cortex-A15 for development purposes or as a test bed for experimenting with Linux on ARM, the Samsung Chromebook is a very attractive bargain priced at $250 USD.
It was surprising to see the wide performance margin the dual-core 1.7GHz A15 had over the quad-core 1.4GHz A9 in the Tegra 3. In a majority of the cases, the Samsung Exynos 5 Dual also easily beat out all of the tested Intel Atom processors. And then there was the Intel Core i3 330M, which was faster, but on the performance-per-Watt this would be a very different story. The Core i3 330M has a 35 Watt TDP while the Exynos 5 Dual operates within a few Watt envelope. Unfortunately due to the varying displays and other hardware differences, an easy power consumption / performance-per-Watt comparison couldn't be done for this article.
