"How smart is your smartphone? It can sync your bookmarks between Chrome on your desktop and Chrome on your phone, but only after you go through the setup process. Open a few apps, fumble around some menus and press some more buttons. Most of that you have to do every time you want your smartphone to do smart things. With the Moto X, not anymore.
Back in April, we told you how the Moto X will feature creepy intelligence. Its going to know when you want to do things, before you even tell it. And if you do have to tell it, it will always be listening, ready for action. Earlier, we told you the Moto X would launch with a MSM8960pro. But thats not all. There are actually going to be eight different cores making the Moto X a contextually aware information powerhouse.
They break down like this:
Four processors cores are dedicated to graphics. By taking this route, youre going to see Android running smoother than ever before. Paired with stock Android, this thing is going to fly in the graphics department.
Two processors cores are dedicated to applications. Let the graphics processors focus on graphics, while two 1.7 GHz processors focus on apps.
One processor will be dedicated to language processing. The low-power language chip will focus on audio sensors, noise cancellation and speech recognition. This will allow the Moto X to use an always-on listening mode, but still retain sufficient battery life.
One processor will be dedicated to other contextual sensors. During his interview at All Things D11, Dennis Woodside said the Moto X would anticipate what you want to do with your phone. Hold it up like youre going to take a picture, your camera will turn on. Thats what this processor is for.
No one else has a chip configuration like this. Its exclusive to Motorola and is what will make this phone smarter than any other phone before it. Google has made it clear that Motorola is being given no special treatment, but its clear that Google is playing a role in the production of the Moto X. Google makes stock Android, with all the bare essentials. Google is going to make the Moto X will all the little things that they really want in a phone that dont make it into stock Android for one reason or another. Think of Motorolas products as getting the moonshot thinking approach. If anything were to kill Nexus, this would be it."
