So its common knowledge the iPhone 3GS is using a Cortex-A8 but has anyone actually verified its running at 600MHz or just underclocked like the two previous phones?
 
underclocked

if it ran 600MHz battery life would suck literally ;) plus it makes for a easy upgrade next year if they can get better battery performance. somebody will probably find a way to overclock it before then. but for now 400 MHZ ain't bad. :D

So..... you're saying that the iPhone 3GS' CPU is running at 400MHz?:confused:

The iPhone 3GS' CPU runs at 600MHz...

No.

And look up the meaning of literally.
 
I'm sure it's not 400Mhz, but somewhere in the median 500s.

I mean, my battery life already sucks :p. I can't even get a day of light usage.
If I get a day without charging, it means I used my phone for about 10 minutes.

to me that isnt credible, it could be reading only the CPU information that is comes with the chip and not the actual multiplyers etc. im not saying its wrong, but there is the chance....

I thought of that but if that were the case wouldn't the memory reading be 256 instead of 253?. That suggesting some parts of the 256 is in use by/reserve for something else

Plus testing out the Accelerometre/GPS leads to real time readings
 
Remember that the new System-on-a-chip (SoC) is made on a 65nm fabrication, whereas the old one were produced at 90nm.
 
I wouldn't sweat the exact clock speed numbers so much. There are many optimizations in the 3GS, not just clock speed, that make it a heckuva lot faster than the 3G. I upgraded from a 3G and it's a huge difference. People that say "4x faster" are not joking. It is, based on just about every kind of test you could run. And you can jailbreak the hell out of this phone, run stuff in the background, etc. and it STILL moves quickly.
