The iPhone 4S won't go on sale until this Friday, but benchmarks for the device have somehow already leaked their way onto the Internet. Tech blog Anandtech posted several CPU and graphics benchmark comparison graphs that pit the iPhone 4S' internal hardware against older iPhone models, competing Android smartphones, even the iPad 2.
Surprise, surprise. The results show that the performance of the iPhone 4S' A5 processor surpasses that of the iPhone 4's A4 chip. The iPhone 4S scored 623 to the iPhone 4's 360 on the general Geekbench test, and notched a respective 560 and 281 on Geekbench's processor integer benchmark. During the "Let's Talk iPhone" press event last week, Apple officials said that the new iPhone 4S would offer up to twice the performance of the iPhone 4.
While the iPhone 4S beats out much of the Android competition in the test results, Anandtech says the iPad 2—which uses the same A5 CPU as the new iPhone—still wins out overall. In the Geekbench test, the iPad 2 scores 751 over the iPhone 4S' 623 in the overall tests, and 687 to the latter's 560 in the processor integer comparison. Because the A5 chips within the two devices are identical, Anandtech theorizes that the iPhone 4S chipset is down-clocked to about 800-MHz, while the iPad 2 A5 chip runs at a full 1-GHz.
