Did we ever find out the actual clock speed?

    We all know the iPhone 4 has a 1GHz A4 processor, but how much of that 1GHz are we using? I think we've all come to the conclusion that it is under clocked, but to what?

    I asked the same question when the iphone 4 came out and no one answered either.

    I think people just dont care about running clock speed anymore.

    My best quess is that it.runs between 700 to 800 mhz. Because my ipad is still runs 10 to 20% faster.

    Bingo.

    It's not like 'Angry Birds' says "recomend 600 mhz or better iPhone" in the app store or anything like that.

    Developers test different phones and then say which iPhone model and iOS version they require for their app to run. That's all you need to know. There's no reason for them to say more than that and no reason for me to care.

    Benchmarks show that the iPhone 4 runs integer code loops at 80% the speed of an iPad, which runs the same A4 processor at 1 GHz. So a very good guess would be that the i4 runs the processor clock at 800MHz.

    This is the app checkup. I can't test the a4 because i dont have an iPhone 4

    The checkup app doesn't show a CPU speed on an iPhone 4.

    Planetbeing suspects that the iPhone 4's clock speed is dynamically scaled. That makes sense -- that would give the best balance of speed and power consumption.

    The better question is why does apple keep this information from the public?

    Say the clock speed is 800mHz... Would Apple really want to advertise this when Motorola is advertising their 1gHz+ phones?
