Orginial iPad VS iPad 2

in Ipad
iPad 2 has been announced. But how does it differ from the original iPad? The two Apple products are pretty similar in many ways, so we thought we'd do a detail comparison to see what have changed on iPad 2.
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.
Like the iPhone 4, the iPad and iPad 2 both have anImagination TechnologiesPowerVR SGX-based graphics chip. Apple is promising nine times better graphics for iPad 2 versus the original iPad. The iPad use PowerVR SGX 535 chip. The new chip is thought to have four pipes, but can that produce a 9x increase?
Storage and Memory
Like the original iPad, the iPad 2 comes loaded with 16GB, 32GB or 64GB of what is presumably still Toshiba-manufactured flash storage. The original iPad had just 256MB of RAM, for iPad 2, Apple will have boosted this 512MB is likely, but Apple won't want to shout about the amount because of the other tablets - it's not cited on the official spec sheet.
As well as matching the memory of the original iPad, the iPad 2 also has the same screen. It's a 1,024 x 768 9.7-inch LED-backlit display with fingerprint-resistant oleophobic coating.
Buttons and other hardware Like the iPhone, all iPads have an ambient light sensor, but you don't get the proximity sensor the iPhone uses when it's close to your face to turn off the screen – not that you need it. As well as the standard dock connector, volume control, Home button and sleep/wake button straight off the iPhone. With the other switch, iOS 4.3 on iPad 2 gives you the option of a mute control or screen orientation lock depending on what you specify.
Size and weight
Not surprisingly, this one's where the difference between the two pieces of hardware is most in evidence - especially in terms of thickness, which is down to 8.8mm from 13.4mm. The iPad 2 is now thinner than the iPhone 4. Interestingly, the original iPad with 3G carries a weight premium of 50g over the standard Wi-Fi model but now the iPad 2 drops the extra weight down to just 12g.
