iPhone 3G S gets Cortex A8 CPU and PowerVR SGX graphics


AnandTech looks inside the new iPhone

Left to Apple, the new iPhone 3G S works on "magic." The marketing angle appears to be not on what's inside, but what it does. Geeks though need to know how things works.

Likely we won't know everything until the new iPhone ships and someone promptly rips it apart. In the mean time, AnandTech has some great tidbits and analysis on key components.

According to the site, the iPhone 3G S gets a significant CPU boost with the ARM Cortex A8. The CPU supports an L2 cache and is expected to run at 600 MHz vs the 3G's underclocked 412 MHz CPU. This all adds a considerable improvement in performance, likely matching Apple's claims of 2X.

The other major tidbit is the PowerVR SGX graphics processor. This upgrade is capable of processing about seven times the geometric output of the 3G, and 2.5 times the fill rate. The question remains how Apple will utilize this chip, so performance may not be that high, but it will be a major improvement over the 3G regardless.
