Early iPad 2 & Apple A5 Benchmarks – Up to 65-Percent Faster than iPad & Apple A4

Earlier this week, we ran a series of tests to compare the JavaScript performance of iOS 4.2.1 and iOS 4.3. This time around, we focused on the performance offered by the iPad 2 and its new Apple A5 processor, when compared to the first generation iPad, powered by the older Apple A4. We ran a couple of JavaScript tests, as well as GeekBench for iOS, to see whether the new tablet really offers a noticeable performance gain, or not. Unsurprisingly, the iPad 2 proved to be faster than its predecessor, and by a hefty margin. Hardware
  • First generation iPad, restored to iOS 4.3 (build 8F190)
  • Second generation iPad, restored to iOS 4.3 (build 8F191)
Tests The three first tests offer a good balance between different areas of the JavaScript language and different types of code, while the last one tests the raw performance offered by each device. Each test was run 10 times, to avoid discrepancies. Results The JavaScript performance gain offered by the iPad 2 ranges between 37-percent and 57-percent, while Geekbench showed a raw performance increase of about 65-percent.

iPad 1 & Apple A4 vs. iPad 2 & Apple A5

iPad 1 vs. iPad 2 – Geekbench results. Notice the lower clock speed of the A5.

While the Apple A5 is clocked slower than the A4, its two cores allow the processor to offer a significant performance gain over its predecessor. As for real-life test results, performance gains are mostly noticeable with apps like Safari, as well as iPad 2 optimized apps such as Infinity Blade. Best of all, this extra performance comes at no premium, as the iPad 2 costs the same as its predecessor.
