Apple Introduces 'The New iPad' with Retina Display, A5X Chip, LTE, 5MP Rear Camera
Featuring an A5X system-on-chip with quad-core graphics, the Retina display offer 44% greater color saturation than its predecessor. All of Apple's stock apps have been optimized for the new ultra-high resolution display and existing apps from third-party developers will be automatically scaled up with text rendered for the new resolution. With additional work, developers can also optimize their entire apps for the new display.
On the camera front, the updated iPad features a 5-megapixel rear camera with advanced optics very similar to those found in the 8-megapixel camera on the iPhone 4S. 1080p video recording is also supported. Voice dictation as found on the iPhone 4S is also included.
Cellular-capable models of the new iPad also support 4G LTE as had been rumored by multiple sources. Supporting data speeds of up to 21 Mbps on HSPA+, 42 Mbps on dual-carrier HSPA+, and 73 Mbps on LTE, the new iPad offers a significant improvement in cellular data capabilities. LTE partners include AT&T and Verizon in the United States and Rogers, Telus, and Bell in Canada. Due to differences in frequency bands, AT&T and Verizon support will require separate models.
On the battery life front, the new iPad offers the same levels as before: 10 hours on Wi-Fi or 9 hours on 4G LTE. As for the device's size, it comes it a scant 0.6 mm thicker than the iPad 2 at 9.4 mm thick, and weighs 1.4 pounds versus the 1.33-pound iPad 2.
