Early AnandTech benchmarks for the iPhone 4S are already here, showing the new device’s SunSpider and Geekbench scores. The iPhone 4S gets a Geekbench score of 623,and a SunSpider score of 13580.
The iPhone 4S’s Geekbench score of 622 places it vastly above the iPhone 4 (370), but below the iPad 2 (751). This represents a 68% performance increase over the iPhone 4. The decrease in performance from the iPad 2 is due to the fact that the iPhone 4 is underclocked to 800mhz, likely to reduce heat and improve battery life.
The SunSpider benchmarks also show that the iPhone 4S has significant increased performance over the iPhone 4, achieving a score that nearly doubles that of its predecessor.
If nothing else, AnandTech’s results clearly demonstrate that the iPhone 4S will bring us some pretty exciting improvements in performance, and I for one can’t wait to experience this in person.
