Just some copypasta from wired.com
"Quantifying graphical performance is notoriously squishy. That being said, Microsoft touts the Xbox One as delivering 8 times the graphic performance of the 360."
'the Xbox One boasts 5 billion to the 360’s 500 million. More concretely, those paltry 512 MB of memory have been boosted to 8 GB."
Now for you camera nerds
"It’s essentially like turning each pixel of the custom-designed CMOS sensor into a radar gun, which allows for unprecedented responsiveness. - even in a completely dark room."
yeah, holy fuck.
and for the lazy
"In fact, the Kinect will be used for that most fundamental of tasks: turning the whole thing on. Xbox One utilizes multiple power states; it can thus ramp up as needed and consume different amounts of juice depending on use, whether games or movies. And it also possesses a low-power standby mode, allowing Xbox Live and game updates to be pushed to the Xbox One overnight — or whenever the box knows your usage is lowest — without keeping the console all the way on. (Don’t worry; you can still play a single-player game without being connected to the Internet.) It also means that when you walk into your room and say “Xbox on,” the Kinect sensor hears you and turns on your entire setup via infrared blast: TV, Xbox One, even your cable box."
some xbox and tv
"Because of that direct pipe from your TV provider to the Xbox One, you can watch TV with varying degrees of Xbox overlay. It can look exactly like your plain old TV interface, being controlled with the original remote. Alternately, you can use Xbox’s electronic programming guide, which presents a lineup based on your favorite channels or tells you what your friends are watching and can be controlled via voice, gesture, and game controller. Or, thanks to Xbox SmartGlass, the second-screen functionality that Microsoft introduced in limited capacity last year across multiple mobile platforms, you can use your smartphone or tablet to change channels with a no-look flicking motion."
"Skype calls while you’re playing a game? Sure."
