Just saw this on Engadget and though that it was interesting. No idea if it's real or not, but it looks as though the next iPad will have an A5X SoC rather than an A6. I don't know if this is merely a difference in naming or if, as the article suggests, that the chip is just more of an incremental enhancement.

Its been treated with Pixie dust, to make it more magical.

The 5X probably indicates the same dual core and possibly oveclocked with a beefed up GPU. I probably would be able to live with it if the GPU is powerful enough to drive the retina screen. The retina screen is the biggest upgrade to me IMO.

Makes sense. No one can seriously describe the ipad2 performance as lacking.
Apple has the fastest chip and the most efficient OS already. This chip is likely a die shrink to 28nm so it opened up some room for clock maneuvering they took advantage of. I'm curious whether the GPU related changes involve a different part or different clocking. Either way, it should be good enough.

Rick,

Wouldn't a die shrnk mean more for battery life?

More likely it'll be 32nm, as that's what Samsung's factories are tooled for. 28nm production comes from TSMC, and they have so many other customers to deal with (Qualcomm, nVidia, AMD, TI, etc..), I don't know if they can guarantee capacity to Apple on a new process.

Only if they decided to use the gained headroom towards the battery life. Since no one is exactly screaming about poor battery life in iOS, they will likely use some or all of the die shrink benefit towards performance while keeping battery life on par with previous generations.

There has been talk in the past about Apple going with TSMC. If they wanted to, I'm sure they could have leveraged themselves into the production cycle, if they wanted to. Indeed, if they stayed with Samsung it's a 32nm chip but wouldn't change much vs a 28nm SoC.

Perhaps some chips, but certainly not all (as sometimes implied by the Apple-Samsung patent spats).
