On the inside, Microsoft has opted for an Intel Cherry Trail Atom CPU, which is passively cooled and allows the device to run silently in the absence of a fan while generating barely any heat. One of the main differences between the Surface 3 and the Surface Pro 3 isn't visible from the outside. It can run any Windows program out there (within reason) and is ready for a free upgrade to Windows 10 as well as all of its subsequent updates. Despite the lack of a Pro moniker, and the fact that it bears more than a passing resemblance to the Surface 2 (it's almost exactly the same size and weight), the Surface 3 has killed off Windows RT and instead comes with Windows 8.1 installed.
