GeekBench has released some of the first benchmarks regarding the iPhone 4S’s speed. Needless to say, the iPhone 4S has similar speed and performance to the iPad 2, which of course, is also powered by Apple’s A5 chip. The iPhone 4S also appears to have 512MB of RAM, as was rumored.
Now to the numbers. The iPhone 4S gets a GeekBench score of ~622. This is lower than the iPad 2’s score of 749, and far ahead of the iPhone 4’s score of 370. That works out to be around 68% faster than the iPhone 4, and around 17% slower than the iPad 2.
The reason for the speed difference between the iPhone 4S and the iPad 2 even thought they share the same processor, is the fact that the iPhone 4S’s chip is likely clocked at 800MHz as compared to the iPad 2’s 1GHz clock speed. This is likely due to the device’s smaller thermal envelope.
With all that said, the iPhone 4S does seem to have graphics about 7X faster than the iPhone 4 as Apple claimed.
