Apple finally unveiled the iPhone 5 today. You can get the full rundown here.

In addition to a better camera, better battery life, better Wi-Fi and LTE connectivity, the device comes with a new A6 processor, which Apple says increases the CPU power by 2X. The graphics are also twice as fast, Apple says (compared to the A5).

“With the new A6 chip, just about everything you do on iPhone 5 is noticeably faster — up to twice as fast compared with the A5 chip. So apps launch, web pages load, and email attachments appear almost instantly,” says Apple. “The A6 chip also offers graphics performance that’s up to twice as fast as the A5. So you can power through graphics-intensive apps and games. And enjoy higher frame rates for smoother, more realistic gameplay.”

“Not only is the A6 chip custom designed to be fast, it’s custom designed to work with iOS 6 to be extremely power efficient,” the company says. “So even at its accelerated speed, iPhone 5 has more than enough battery power to last throughout the day — up to 8 hours of browsing on a cellular connection, up to 8 hours of talk time, and up to 10 hours of video playback time.”
