According to Apple, the new 1GHz dual-core A5 chip in iPad 2 unveiled at ‘Come See What 2011 Will Be Year Of’ event is 1.5x faster than the iPad 1 on iOS 4.3 and 4x faster than the iPad 1 on 4.2 and it also improves graphic performance by up to 9 times. Folks at CNET UK who got a chance to get their hands on the new iPad after the event, ran a quick benchmark test to find out exactly how fast it is. They carried out JavaScript SunSpider benchmark test to find out the real world Javascript performance on iPad 2 and compared it with the original iPad (iPad 1) and competing Android devices. Here is what they had to report: Incidentally, when you compare the iPad to the other devices we tested, Android phones and tablets don’t come out particularly well. The Galaxy Tab is more than 3x slower than the iPad 2 in this test, and about 2x slower than the original iPad with the new software. The Google Nexus S smart phone doesn’t fare too well either, at nearly 3x slower than the iPad 2. CNET also reports that iOS 4.3 that comes pre-installed in iPad 2 is also another reason for the improved Javascript performance. Apple has ported the Nitro Javascript engine used in desktop version of Safari to iOS 4.3, which Apple claims loads Javascripts two times faster. The tests carried out by CNET also indicates that it is a lot faster: There’s really good news for iPhone 4 owners out there: when it arrives, iOS 4.3 will deliver a 2.5x speed increase in this test. Once we’d updated the software on our iPad 1, the gap between the two devices narrowed considerably, with the iPad 2 coming out at just 1.5x faster than the iPad 1. iOS 4.3 will be released on March 11 for iPhone 4, iPhone 3GS, iPod Touch 4G, iPod Touch 3G and iPad, the same day as the launch of iPad 2. It goes without saying that iPad 2 will be faster than the original iPad but it is always interesting to find out how much faster it really is. Share your thoughts in the comments section below.
