apple a4 ipad cpu:
· There's not much revolutionary here. In fact, the A4 is quite similar to the Samsung processor Apple uses in the iPhone [3GS].
· It's clear from both hardware and software that this is a single core processor, so it must be the ARM Cortex A8, and NOT the rumored multicore
A9.
· It's quite challenging to identify block-level logic inside a processor, so to identify the GPU we're falling back to software: early benchmarks are showing similar 3D performance to the iPhone [3GS], so we're guessing that the iPad uses the same PowerVR SGX 535 GPU.
· The iPad has 256 MB RAM, same as the iPhone [3GS].
· The A4 sips power. In fact, power consumption is probably the reason Apple hasn't stepped up performance much from the iPhone [3GS]. In order to get 10 hours of battery life, the entire iPad (including display) has to pull less than 2.5 Watts on average.
