iOS 4.3 boosts first-gen iPad browser speed by 18 percent
The answer is yes. The test ran 18 percent faster under iOS 4.3 than under iOS 4.2 on the same iPad, the 64GB Wi-Fi + 3G model, with a score of 508 versus 430. (Larger numbers are better.) Those results bode well for the iPad 2, which sports a dual-core A5 processor versus the original iPad’s single-core A4.
For comparison, a single-core Verizon iPhone 4 running iOS 4.2.6 (there is no 4.3 update for this model) scored 482, while a dual-core Motorola Mobility Atrix 4G Android 2.2 smartphone scored 662 and a dual-core Motorola Xoom Android 3.0 tablet scored 897. A quad-core i7-based, 2011-model MacBook Pro running Safari 5 scored 2812, and a prototype Chrome OS “Chromebook” laptop scored 1310.
