Microsoft says that the Xbox One is roughly eight times as powerful as the Xbox 360 at the end of the day. In addition, the ramifications of Microsoft's cloud computing initiative could be significant. The company has stated that consoles will be able to offload calculations to cloud processors, which could be significant if developers find it useful to take advantage of.
* The Xbox One's Wi-Fi Direct capabilities allow it to use its multiple 802.11n Wi-Fi radios to communicate simultaneously with both a standard wireless network and directly with other Wi-Fi devices.
