While the 4th generation iPad and iPad Air currently sport 1GB of RAM, Taiwan's TechNews reports that the next iteration of the iPad Air will get an exclusive update to 2GB. Unfortunately the news site also reports that the Retina iPad Mini second generation will be left behind, still sporting 1GB of RAM.
Apple has probably been keeping the RAM at 1GB to save money on costs and space inside of the device. More RAM also equals more battery usage, and we all know how well the battery does in most iPad models.
Rumors have been flying around that the iPad would be receiving split-screen multitasking in iOS 8. However the rumors also claim that the feature won't be ready for release until a future update, such as iOS 8.1. Split-screen multitasking on the iPad models has been rumored to run two separate apps, side-by-side in sizes like; 1/4, 1/2, and 3/4. Running two apps will definitely put the tablet to work, so more rams and the A8x process will come in handy for sure.
As with previous years and rumors around the web, Apple is planning to unveil the new iPad Air 2 and Retina iPad Mini 2nd generation at an event, separate from the iPhone event, in October. A little bird also told us that this is when Apple might be planning to unveil the rumored iWatch, however the device might not release to the public until next year.
