Info on the Apple iPad processor....
*****************************EXCERPT*************************************
Update #1, January 28, 2010 22:22 GMT/UTC - Following the request for comments, we were incline to update the story. First of all, we do not have concrete information about the number of cores inside the Apple A4 "CPU that it isn't" i.e. A4 SOC. We were told that the ARM licensed its CPU and GPU technology to Apple. That's it. Out of that technology, Cortex-A9 is intended for manufacturing in advanced manufacturing process such as 45nm, 40nm, 28nm and so on, while Cortex-A8 doesn't have advanced video processing capabilities that Cortex-A9 has. As the time progresses, we'll know more about what LEGO brick components did Apple use to create the A4. One thing is certain - it uses ARM IP throughout the silicon.
Good discussion on subject
