Changing Temperature, Changing Density. Most matter increases in volume when it gets hotter. For example, if an iron rod is heated, it will get longer and fatter and its density will decrease. This happens because the mass of the rod stays the same, but its volume increases. The increase in the volume of matter with increasing temperature is called expansion. When cooled down, most matter decreases in volume and increases in density. This decrease in volume is called contraction.
USB-C also builds on the new USB 3.1 standard so to all intents and purposes is the connection type that brings in the new power and speed advantages of USB 3.1. USB-C is still backwards compatible with existing USB variants, but that of course requires adapters.
Microsoft says it is 8x more powerful than the Xbox 360. USB 3.0 is a nice feature, as is the HDMI in and HDMI out on the back. The former is used for taking TV signals, which we will come to later. As for the processor, this is an eight-core AMD system on a chip, which we presume will be extremely powerful.
