Characteristics

The Cortex-A17 processor is optimized for maximum performance for mobile mid-range power budgets. With 60% more single thread performance over the Cortex-A9 processor, the Cortex-A17 processor is the fastest mid-range solution available.

Additionally, the Cortex-A17 processor offers 50% performance uplift over Cortex-A9 on Neon and FPU workloads, boosting performance of any code leveraging this capability such as audio and video codecs.

With expected frequencies beyond 2.5GHz in 28nm, the Cortex-A17 processor can be scaled in size to meet a range of different application demands. Topologies are expected to vary depending on the use case due to the malleability of the Cortex-A17 processor.

Chromebit棒状电脑，使用瑞芯微的RK3288-C芯片

今天看到合作伙伴瑞芯微 Rockchip 发表的博客，有关RK3288-C（Cortex-A17, Mali-T760)应用于最新的Chromebit。感觉今后可能是一个很好的卖点。大家对于随身携带笔记本电脑已经有些厌烦了，我个人就最不喜欢出门背着我的ThinkPad. 如果今后所有的电脑都能简化到一个U盘这么大就好了。外设的屏幕和键盘等输入设备都可以另接，或者使用卷曲键盘和类似于戒指或者手镯的新式鼠标，那么出行就能更方便。当然，可能今后手机也能完成目前笔记本电脑所做的大部分工作。便携式电脑和手
