Most people’s attention might be on the iPad 2 (s aapl) launching tomorrow, but iOS 4.3 brought some impressive improvements to existing hardware, too. I followed the same testing I’ve used when benchmarking updates before, only this time I applied it to the iPad. On both devices, I cleared all running apps from the multitasking menu and powered off then back on the device to ensure the there were no background tasks running to interfere with test results.
iOS 4.3 Update Tested
The only concern I had was that the benchmark apps were all iPhone apps, not true iPad apps, but it shouldn’t affect the overall results. I used GeekBench 2 ($0.99), Gauge Mathematical Tool (free), BenchTest ($0.99), SunSpider (free) and V8 (free) to test the performance of each OS version on the iPad. I performed all the tests on the same device, both before and after the upgrade.
Results for the Wi-Fi iPad
Results for the iPhone 4
While I couldn’t upgrade my iPhone 3G, I could apply the latest update to my iPhone 4 for comparison to prior results and see how it was affected by by the upgrade. Unlike on the iPad, I’ve been maintaining benchmark results on my iPhone 4 for some time now, so I have some historical data to compare the latest tests to:
For what you get in the form of features withe the iOS 4.3 update, and for the almost insignificant general performance hit on the iPad, the upgrade is overall a great one. Any time you get more features for little or no degradation in performance is a good thing.
