Lab Tested: The new iPad 2 and old iPad 2

As reported by sites like AnandTech, the folks at Chipworks discovered that Apple is using a different production process for its A5 processors. The company switched from using Samsung Semiconductor’s 45nm process to Samsung’s 32nm process, reducing the size of the chip by 41 percent.

The smaller size could mean better performance or lower power consumption. To see if we could find any measurable performance differences between the two versions of the iPad 2, we purchased a brand new model and ran our standard set of tests on them.

In our performance tests, we found the two iPad 2s to be nearly as identical as their outside appearances.
