    CNET.co.uk did some Javascript benchmarks on the new iPad running iOS 4.3 and compared them with other iOS devices and a few Androids.

    The results are pretty impressive. Where the iPhone 4 and iPad lagged behind both Android devices using iOS 4.2, popping iOS 4.3 with the new WebKit 2 browser engine in the devices dropped more than half of their rendering time.

    As you can see, the iPad 2, with its more powerful processor, and perhaps helped by some additional RAM, is over 50% faster than the previous iPad.

    Darn. Awesome! Can't wait for iOS 4.3 and iPad2~~

    Wow, didn't know 4.3 increased speed by that much...

    The iPhone 4 was slower than the original iPad. The A4 in the iPad ran at 1 GHz. The A4 in the iPhone 4 ran at 800 MHz.

    Will the 4.3 update make a significant increase on safari speed for my Iphone 3GS?

    There's another thread somewhere on this site in the last few days where one of us (forum members) posted experiences of Safari browsing after upgrading their iPad 1 to 4.3GM. It agrees with the findings above, i.e. browsing is much faster on the iPad 1 with 4.3 vs 4.2. Also, apparently the old 4.2 issue has gone away where, when visiting a web page with lots of images in it, Safari would stop loading images after a while and start displaying the blue "?" symbols. Unfortunately the issue of constant page reloads when switching between multiple open tabs isn't fixed with 4.3 on the iPad 1 but hopefully the iPad 2 will at least alleviate that if it does have the rumoured 512MB of RAM.

    Will other browsers (iCab, Atomic) see the same speedups? I would think the answer is yes because the faster JavaScript engine and rendering code all lives in WebKit I think, which all third party browsers have to use if Apple is going to approve them, so I hope they will all benefit too.

    I would have thought so. They've radically overhauled the JavaScript engine and probably done some other tweaks in the rendering. All this stuff is in a software module within iOS called WebKit so I would expect you to see speedups on all platforms, it shouldn't be hardware dependent (except for whether iOS 4.3 is available on a device at all, and it is for the 3GS).

    You'll know for sure this Friday, assuming the Apple servers don't buckle under the release-day strain. I always leave it a few days before upgrading, partly to see if any bad bugs emerge once it goes on mass distribution, and partly to let the servers get less busy.

    aren't those just JAVA benchmarks?

    ...I'm sorry, but, is this test a test of the overall speed of the iPad or just how fast it renders javascript (such as in safari). If it is the latter then it is not an accurate graph of the overall speed of the devices. ...however, I am looking forward to faster Safari browsing w/iOS 4.3 on my (old) iPad! :)

    Exactly. This is comparing pure javascript performance only. This is not realworld surfing of pages. Their were other tests done that compared actually loading sites and the differences between 4.3 and 4.2 were negligable. Now if those sites use alot of javascripts, then you would see a bigger improvement. The iPad 2 will see performance increases across the board.

    The iPad 1 clocks the A4 ARM CPU at 1 GHz. The iPhone 4 is thought to under-clock the same A4 ARM CPU to only 800 MHz, so as not to run down the much smaller battery too quickly.

    Whatever is in the iPad 2 runs Javascript 55% faster. Since Javascript normally only uses 1 core, this might mean that the iPad2 ARM CPU is a version of the Cortex A9, or a much much faster A8.

    Sorry, but I don't see from these stats how the conclusion can be made that iPad2 is 4 times faster than iPad1:

    iPad2 = 2097ms
    iPad1 = 3261ms

    Seems to me the iPad2 is moderately faster than iPad1 from these numbers - 35% more, not 4 times. The Galaxy at 7066ms looks like the significantly slow device here.

    just run this myself.

    My, not very cutting edge PC by today's standards scored:

    Total: 264.7ms


    My iPad running "Perfect Browser" scored:

    *** I'm still waiting for it to finish! ***

    Yay finished! 8820.7ms

    I think it's 4x faster than the iPad running the current revision of the OS, which clocks in at 8321ms.

    And for what it's worth, my crappy old work PC (2.8ghz Pentium 4 with 1.5GB of RAM) running Firefox 3.6 clocks in at 2179.4ms, so let's have some perspective here.
