Apple It's one of those days again: Apple held a product announcement today, announcing several new products. The most important of which was rumoured about for a long time now: a smaller iPad. It's called the iPad mini, and has the potential to become the best-selling iPad - and thus, the best selling tablet.

I was hoping they'd at least put an A5X chip in there rather than just the A5.


Apple is not going to put the A5X in anything new - it doesn't make sense for them to do that. The A5X is still a 45nm chip, while the currently manufactured version of the A5 is 32nm - the A5X is over twice as big and uses ALOT more power.

Its all about maximizing profitability on varied products - the A5 is used in ALOT of devices (iPad2, iPod Touch, AppleTV, and now iPad mini). Its tiny, so you can make a whole lot of them cheap - and it is packaged with RAM on the chip, so it needs much less PCB area. Apple is going to put it into anything they deem "value oriented".

The A5X is is a layover from the previous generation. It is probably cheaper for Apple to make an A6X now, as it is much smaller and uses the same process node as the A5.

I expect you will either never see another new product with an A5X in it, or it will get shrunk to 32nm first (like the A5 was) if there is ever an "Old New iPad" type SKU.

Besides, your really don't need 4 GPUs to push a 1024x768 screen. Other than the GPUs, there isn't all that much difference between the two chips.
