Anand, estimating by die size, says A5X looks like 28/32 nm. http://www.anandtech.com/show/5681/apples-a5x-die-and-size-revealed http://www.anandtech.com/show/5681/apples-a5x-die-and-size-r... Qualcomm's chip is confirmed as still being the 45 nm model. http://www.macrumors.com/2012/03/08/new-ipad-appears-to-utilize-qualcomms-mdm9600-baseband-chip/ http://www.macrumors.com/2012/03/08/new-ipad-appears-to-util... So for next year's iPad we can expect a tock architechture update (to A-15) for the SoC and a tick process shrink for the baseband chip. Not sure how many batteries they'll be able to throw out but hopefully some and it'll be thin again.
