iPad 2, the new A5 CPU power savings than the original version.

The earlier it is discovered that the Apple iPad 2 16GB on sale today adapts to the smaller A5 CPU. I have tested it out and save more than enough.
Web anandtech.com. Tested iPad 2 (code iPad 2,4), the CPU's A5 of a 32 nm (from 45 nm) showed the same type can be used for more than surfing the Web, such as the iPad 2 iPad 2,. 4 can be used up to 11.7 hours of iPad 2 to work 10.1 hours or at the game Infinity Blade 2 version is 7.9 hours and the original version is 6.12 hours at the end to an hour to open the video in 720p. differ up to 2 hours and more than iPad (3rd Gen) to 4 hours together.

I see that the power consumption of the iPad 2,4 with iPad 2 and iPad (3rd Gen) will be more evident in the work that each individual consumes much different. For example, while playing Infinity Blade 2 The iPad 2,4 4.3W power consumption of 5.1W, and the iPad 2 iPad (3rd Gen) power up to 10.3W on the temperature of the CPU smaller iPad 2,4. It makes the heat spread out down to the test with Infinity Blade 2 temperature with iPad 2 it is one degree Celsius (33.2, 34.2) for iPad (3rd Gen) heat not care about media to 41.9 degrees. Celsius
