It was confirmed on Thursday that iPad mini is using the same A5 processor found in the fifth-generation iPod touch, meaning the SoC is built on Samsung's 32nm process first introduced in the refreshed iPad 2 and third-generation Apple TV.
Chip analysis firm Chipworks took a closer look at the iPad mini's processor to see if Apple moved to an updated process as it did with the incremental iPad 2 revision in May, which saw a process change from 45nm to 32nm.
The firm noted in its report that Apple quietly changed the process in the A5 chip when it introduced the New iPad and its touted A5X SoC.
"Apple (likely) plays it this way because they don’t want people evaluating their products based on 'commodity' technical specifications, but based on the overall experience with the device," Chipworks wrote.
Based on the company's generational process changes, some speculated that the iPad mini would carry a third-generation A5 chip even more efficient than the 32nm version found in the iPad 2 and Apple TV. Chipworks discovered, however, that the tablet's SoC is the same 32nm component found in the most recent iPod touch.
"Basically, we put our device in for a cross section and the images show the same contacted gate pitch and the same high-k metal gates, so we are comfortable with this conclusion," the firm said, referring to Samsung's 32nm process.
The continued use of the legacy A5 chip may not come as a surprise to most, as Apple was said to be keeping component costs down in order to offer the mini at a relatively inexpensive price point.
Chipworks' in-depth look comes on the heels of iFixit's usual teardown which found the 7.9-inch tablet to share design cues and parts design with the iPhone 5.

Troll me a poem. A8 at 12nm made by google.:smokey:
This is interesting. During the keynote, Apple very clearly called the processor in the iPad mini an A5X, not an A5. They even put it up in a graphic on the screen.

They do show an A6X but that's earlier for the iPad (4) part. Note that the X is for GPU and bandwidth required to push all the additional data to the display. This is simply not required for the iPad 1, 2, or mini, which all only have a handle more pixels than the iPhone and iPod Touch with Retina displays.

A5. Right on the website.
It sure looks pretty sitting on my bench syncing apps across... it feels very light and no where near as 'solid' feeling as my old ipad2.. but tiny. Jealous of my little one, who is it for.
