Hardware, Embedded Systems And yet another item on the iPad? Are we serious? Yes, we are, since this one is about something that even geeks who aren't interested in the iPad itself should find intriguing. Steve Jobs said yesterday that the iPad is powered by an Apple A4 processor, but contrary to what many seem to think - it wasn't designed in-house at all.

Out of order? I haven't heard that. The current claim is that it is a Cortex-A9 with two cores. This is largely equivalent to having two Cortex-A8s, though there is some flexibility in execution unit choices I believe. Since the Snapdragon is a Cortex-A8 which has been tuned a bit and clocked to 1GHz I would say that the comparison between the Apple A4 and a hypothetical dual-core Snapdragon is very fair.

the cortex a8 is an in-order-design, the cortex a9 is an out-of-order design. arm offers a single-core design called cortex a9 and a multi-core design called cortex a9-mp.

Ah, right you are, I had misread the datasheets.
