Updated A5X chip destined for Retina iPad mini: Arment

If the next Apple TV was to feature Apple’s A5X processor found in the third generation iPad, it would be “a low-volume production trial preceding its deployment in a much higher-volume product”, that product being the Retina iPad mini, suggests a technology expert.

In addition, this version of the A5X chip – called the A5XR2, according to an AnandTech report – is thought to have had a process-shrunk update. This is significant because the A5X chip is “huge, hot, power-inefficient, and too slow for CPU-bound operations”, according to technology writer and Instapaper founder Marco Arment.

Arment wrote on his blog: “I couldn’t believe that Apple would use the iPad 3’s A5X in anything again since it was huge, hot, power-inefficient, and too slow for CPU-bound operations on Retina iPad pixel volume.”

A process-shrunk A5X, on the other hand, “probably won’t contain faster CPUs, but it would be smaller, cooler, and more efficient,” he adds.

Arment speculates that Apple’s real motives for using this new version of the A5X chip in the Apple TV is as a trial before rolling it into a Retina version of the iPad mini. He writes: “It’s obvious, in retrospect, what this is probably for: the Retina iPad Mini.”

Arment has previously suggested that the reason the first iPad mini didn’t have a Retina display was down to performance and power concerns.

    I prefer the Kindle Fire HD. The interface is great and it’s very easy to use. Check out its Amazon page(http://amzn.to/11SRHbE) if you want to compare what they bring to the table.

  2. Peter T. says:

    Many people, like me, have spent years buying apps and content for iOS devices. Fire HD might be good, but it is not so good that it would encourage anyone to throw-away their iOS apps and content and re-purchase the lot – assuming the equivalents exist. Putting that aside, Android tablets come only in 16:9 format. It is useless for any real work in portrait mode. Sure, it makes videos better, for most people that is hardly the main reason for their decision to purchase a tablet. Then there is the issue of apps in the Android store, apps that aren’t checked or tested and which are simply malware. Why would sensible person give-up a secure store with iOS for one of the most insecure stores ever devised? And those are just a couple of the issues . . .

    Enjoy your Kindle HD, but please stop kidding yourself that it is in any way a better option to an iPad.
