iOS5 Boosts Existing iPhone Speeds While iPhone4S is 74% Faster Than The iPhone 4

A recent benchmark scoring of popular smartphone models depicted Apple’s iPhone 4 running iOS 4.2.1 as achieving a score of 31,375 in Rightware’s BrowserMark suite of tests, aimed at profiling the web browser proficiency of a system.

A number of smartphones have beat Apple’s former flagship model in BrowserMark scores, with the super fast Motorola Atrix 4G, LG Optimus 2X and Samsung Galaxy S II all ranking in the ballpark of 50 to 53,000.

Those phones have significantly faster processors than last year’s iPhone 4 with its single core A4 chip, which appears to run at around 800MHz. The Motorola Atrix and LG Optimux 2X use a dual core 1GHz chip, while Samsung’s Galaxy S II has a dual core chip that runs at 1.2 GHz.

When upgraded to iOS 5 however, today’s existing iPhone 4 achieves a score in the same zone as newer dual core chips: in our test, AppleInsider achieved a score of 51,302. Users can run the test on their own devices here.

According to a video of the new phone published by mictvstation, the new iPhone 4S hardware achieves a score of 89,567, a score over 74 percent faster than the existing iPhone.
