“Using some of the integer and fp tests of published Geekbench scores we can already conclude that Apple is shipping a lower clocked A5 in the iPhone 4S than it does in the iPad 2,” Lal Shimpi and Klug report. “This naturally makes sense as the iPhone 4S has a much smaller 5.25 Whr battery. Based on the Geekbench results it looks like the iPad 2 is clocked around 25% higher than the iPhone 4S, pegging the latter’s clock speed at 800MHz.”
Lal Shimpi and Klug report, “The GPU power in the 4S should be more than enough to run any well written, current generation title at well north of 30 fps on its display.”
