iPhone 4S is not only the must have phone this holiday but it’s also the fastest. At the moment anyway. Shipping of the phone that sold over 1 million in just 24 hours started this week. Although some lucky few already have their hands on one. The new iPhone 4S has a A5 chip inside. The same chip that is powering up the iPad 2.
The results of Geekbench have the iPhone 4S running at around 800MHz, with a score of 623. That is just a tad bit slower than the A5-based iPad 2, yet but much faster than the iPhone 4. The GLBenchmark 2.1 which tests GPU performance (graphics) has the iPhone 4S performing better than the Galaxy S II but not the iPad 2. The test is ran in 1280 x 720, off-screen render mode. So all things considered this is the fastest phone for now until Quad chips come out.
