Apple A5 from the Apple TV 3 – and an iPad 2! » Chipworks

Pictures of the two different A5 chips

From: 9to5mac, the two Apple A5 cpus in question

Not only did Apple roll out a new processor that was not what it was advertised to be, but it also snuck in a new process technology for the manufacturing of this new A5. The previous generation A5, part number APL0498, was manufactured on Samsung Semiconductors’ 45 nm LP CMOS process. This new A5 processor is manufactured on Samsung’s new 32 nm high-k metal gate, gate first, LP CMOS process technology.

Check out the article at the Chipworks website, just follow the link above. They have a great rundown of what they discovered in their investigation of the most recent Apple A5 chips. These chips are appearing in a newly revised AppleTV but have also appeared in more recently manufactured Apple iPad 2 as well. There was some amount of surprise that Apple didn’t adopt a shrunk down die ruling for the A5X used in the iPad 3. Most of the work went into the integrated graphics of the A5X as it was driving a much higher rez ‘Retina’-like display.

Very, very sneaky of Apple to slip in the next generation smaller die size on a ‘hobby’ product like the Apple TV. This is proof positive that when someone says something is a hobby, it isn’t necessarily so. I for one am both heartened and intrigued that Apple is attempting to get a 32nm processor out there on their ‘low power’ low cost products. Now that this part has also been discovered in the more recently constructed Apple iPad 2 units, I wonder what kind of heat, battery life differences there are versus an early model iPad 2 using the A5 part number APL0498?

Keeping up with the Samsungs is all important these days and Apple has got to keep its CPU die rulings in step with the next generation of of chip fabrication giants. Intel is pushing 22nm, Samsung has been on 32nm for a while and then there’s Apple sitting 1 or 2 generations behind the cutting edge. I fear this may have resulted in some of the heat issues that were first brought to people’s attention by Consumer Reports weeks after the introduction of the iPad 3. With any luck and process engineering speed, the A5X can jump ship to the 32nm fabrication line at Samsung sooner rather than later.
