According to code references discovered in iOS 7 beta, Apple is testing a new version of iPad mini powered by A6 chip, which currently powers the iPhone 5.
The code references also reveal that this new iPad mini will not feature a Retina Display.
9to5Mac reports that this was discovered by developer Nick Frey in a hidden file that provides the list of devices compatible with iOS 7.
Apple is considering three new iPad mini models: iPad “2,8,” iPad “2,9,” and iPad “2,10.” The respective code names for the devices are J75, J76, and J77. This points to one WiFi-only model and two cellular-compatible models (just like the current iPad minis). [..]
[..] As for what these new iPad minis will feature, the references state that the devices include the “s5l8950x” processor. This is the same A6 system-on-a-chip inside of Apple’s iPhone 5, and this would offer significant speed improvements for the iPad mini compared to the current A5-based model. The A6 chip will mean that users could move around the operating system at a quicker pace, load up movies more quickly, and see better performance and frame-rates while playing games.
The internal code names for current generation iPad mini are iPad “2,5,” iPad “2,6,” and iPad “2,7.” So the code name suggests that the new version will most likely be an incremental update.
9to5Mac also reports based on the code references, this new iPad mini may not feature a Retina Display:
From the references, we can also infer that this potential iPad mini model will lack a Retina display. The versions of these references for Apple’s Retina display devices, such as the iPhone 5 and fourth-generation iPad, include hooks to images at a “@2x” mode. “@2x” is how developers reference app artwork that is built for a Retina display device. However, these new iPad minis lack the “@2x” hook, including only references to non-Retina images.
These is in line with recent rumors that have indicated that Apple may launch a refreshed iPad mini later this year, followed by the Retina iPad mini early next year.
With the launch of the new Nexus 7 last week, which features a Retina-like HD Display, there is pressure on Apple to launch a Retina iPad mini.
