A lot of people want to know the differences between the original iPad and iPad 2 unveiled recently. Here’s a quick rundown of what’s changed, and what hasn't changed.
Original iPad VS iPad 2 - Size
The iPad 2 follows the style of super-slim iPod touch, measuring 0.34 inches in thickness and weighing in at 1.33 pounds. These changes might sound subtle, but once you feel the iPad 2 in your hands, the difference is significant especially when carrying the tablet for extended periods of time. Apple is quick to point out the iPad 2 is 33 percent thinner and up to 15 percent lighter (depending if you buy the WiFi or WiFi+3G model).
Original iPad VS iPad 2 - Processor
The iPad A4 is an ARM Cortex-A8-based core clocked at 1GHz. It's a fully-integrated system-on-a-chip (SoC), that was rumoured to be manufactured by Samsung for Apple. The iPad 2 introduces the A5, a dual-core chip based on the new ARM Cortex-A9 design. That's the same basic architecture as the other dual-core tablet processors such as the Nvidia Tegra 2. The A5 is clocked at 1 GHz too.
Original iPad VS iPad 2 - Screen
No change here - The iPad 2 makes use of the same 9.7-inch LED-backlit IPS 1024 x 768 screen as the original iPad. At this point one unknown relating to the screen is what graphics processor Apple has used. The original iPad used a PowerVR SGX 535 chip. We’ll have to wait for the teardowns to find this out.
