Having used the Chuwi Hi13 with the same chipset but a slightly higher resolution. I can attest that performance will be good, but not on the level of Kaby Lake or Skylake powered tablets or Ultrabooks. Multitasking will also benefit from the 6 GB RAM. However, when it comes to gaming, performance will be what you expect it to be, as I have tested on Dota 2 and similar games, it will struggle with FPS drops and unstable FPS. But for web browsing, multitasking and other light games, the Laptop is quite good. Also worth noting that it is a non-touch screen but does come with Dual Band WiFi Support, Rather Large Battery and an all aluminum build. Making it one of the best value pure notebooks you can have.
For your information, this is not the Surbook, It is quite different, the information on the it is still not final because it is still under crowdfunding.
