According to a report published by AppleInsider, Analyst Ming-Chi Kuo of Concord Securities has come up with a report saying that iPad 2 won't get higher resolution screen and will be using the same 1024x768 of the original iPad.
The report says:
The improvement of iPad 2 display focuses on thickness and anti-reflection, not resolution. iPad 2 display module is 30~35% thinner than iPad 1 and it's helpful for better form factor.
Thanks to anti-reflection, iPad 2 could have better sunlight readable experience and it's helpful for Apple to compete with Amazon's fast growing Kindle business.
The most important reason why iPad 2 won't have retinal display is yield rate of panel making. At this point, making high resolution and bright IPS/FFS panel is not easy and the production volume and cost couldn't meet Apple's requirements
Apart from this, the report also says that the iPad be powered by a dual core processor and will boast SGX543 graphics.
iPad 2 will use [ARM] Cortex-A9 dual core processor running at 1.2GHz. Increasing 1~2% single core processor clock results in a 3~5% power increase and dual core could get a better balance between computing power and power consumption. That's the reason why Apple will use dual core for iPad 2
iPad 2 will also sport a GPU using Imagination's SGX543 dual core graphics technology which is 200~300% powerful than iPhone 4
Last but not the least; the report also says that the iPad 2 will be featuring two cameras and hints that a SD Card slot may be possible.
iPad has two cameras. Front camera is 0.3 mega-pixel [VGA, like iPhone 4] and rear one is 1 mega-pixel [like iPod touch, rather than iPhone 4]. Front camera is for Facetime and Photo Booth and 0.3 mega-pixel is enough because the resolution of iPad 2 is 1,024x768. Rear camera is for applications such as video recording and augmented reality
According to latest rumors, the iPad 2 is said to be launching on either the first or second Saturday of April. We have extensively covered all rumors related to the next iteration of Apple's magical tablet and until and unless we receive official details about the device from Apple itself, we are left with these rumors to judge what exactly the next iPad may turn out to be.
