that speaks more about the architecture and requirements of ChromeOS than about ARM SoCs. For example, I have Firefox OS running pretty well on an APC Paper with specs so modest that they are trumped by most mid-range smartphones these days. Both systems are very similar in the sense that its a linux kernel and the interaction with the user happens on HTML5 based apps but one is striving to run on single core with 128mb of RAM and the other is running on Chromebook Pixel which is one of the best laptops available in the market today.
