Apple's much-awaited Apple iPad Air, also referred to as iPad 5, recently made it debut amid much frenzy in the technology world.

The design philosophy of the newly-launched device is different and way ahead of other rival tablets. However, its specifications fail to impress.

Taking into comparison the fourth-generation iPad, it has been noted that Apple is running out of innovation and technology as both iPad 4 and iPad Air share nearly the same specifications with minor tweaks.

Here is a comparison, or rather similarities, between the latest iPad Air and its previous iteration iPad 4 (Wi-Fi + Cellular):

Display

The display sections of iPad 4 and iPad Air are exactly the same. Both feature a 9.7-inch LED-backlit IPS LCD capacitive touch screen with 1536 x 2048 pixel resolution and 264ppi pixel density. They even carry the same scratch-resistant glass and oleophobic coating screen protection, reported GSM Arena.

Besides the same screen size and features, Apple has managed to make iPad Air slimmer and shorter, cutting out the bezels from 9.50 x 7.31 x 0.37 inches to 9.45 x 6.67 x 0.30 inches.

Memory

Both tablets come in the 16/32/64GB storage variants. The RAM for iPad Air is not known, but one can expect it to stay the same as 1GB as seen in iPad 4.

Camera

iPad Air and iPad 4 carry the same 5-megapixel autofocus camera with Geo-tagging, touch focus and face detection features. The 1.2-megapixel front camera is also shared by both tablets. 

The only difference in this aspect is that iPad Air comes with HDR feature which is lacking in iPad 4.

Processor

The power aspect sees a considerable change in iPad Air with a Apple A7 dual-core 1.3GHz Cyclone processor. In comparison, iPad 4 sports an A6X dual-core 1.4 GHz processor.

Battery

Both tablets feature a non-removable Li-Po battery. The battery capacity of iPad Air is not mentioned but one can expect it to be bigger than iPad 4's 11.560mAh non-removable battery.

Taking note of the key specifications of the device, iPad 4 owners shouldn't see the need to upgrade to iPad Air as major specifications are carried over to the slimmer version. Based on the speed of Apple's innovation and technology, users can expect just tge addition of fingerprint sensor in the next model which might be tipped as iPad 6.
