Apple made a big deal about the iPad's A4 running at 1GHz, but they've never said how fast the iPhone 4's processor is. In the teardown, iFixit mentions that the iPhone 4 uses an A4 but never gives a clock speed. Has anyone been able to find out how fast it actually is?

According to MacRumors and some German source the iPhone 4 is somewhat slower than the iPad, but still significantly faster than the iPhone 3GS. I guess that its A4 CPU is clocked at about 750 - 850 MHz.

+1. Also, it actually has more RAM than the iPad too. (512 vs 256) – jmlumpkin Nov 15 '10 at 13:10

The iPhone 4 is based on the same processor that is seen in the iPad and has a clock speed of 1Ghz.

The iPhone 4 also has 512mb of RAM which is double that of the 3GS and although never officially announced also double that of the iPad.

its the same processor, but its not clocked at 1GHz like the iPad. – jmlumpkin Nov 15 '10 at 13:10
-1. It's clearly not 1 GHz (see the benchmarks). Apple has a tradition of underclocking the iPhone's CPU since the very first generation. – MrMage Nov 15 '10 at 19:32

Though it's not confirmed, most sources claim that the A4 in the iPhone 4 is the same processor that runs the iPad, clocking in at 1ghz as you suggested.
