iPad Air vs. iPad 4: Specs and performance of two iOS-powered tablets are compared in this review. We look t Apple’s lightweight flagship, the iPad Air, and it’s former main tablet, the iPad 4. Which of this tablet would you opt for?

The iPad 4 retails from $399 to $529, while the iPad Air costs from $499 to $929. Although the Air has considerably better specs in some aspects, many people are still asking if the price upgrade from the iPad 4 is worth it. Now, if you’re in the market looking for the perfect tablet for you, here is a quick rundown of the two Apple models’ specs to help you decide which is fit for your needs.

DESIGN

With a thinner (7.5mm vs 9.4mm), smaller (240x169mm vs 241x185mm), and lighter (469g vs 662g) body than the iPad 4, the Air is the clear cut winner in this round. In fact, the Air is "20 percent thinner and 28 percent lighter" than the iPad 4th Gen., according to Apple.

The iPad Air is much lighter primarily because it uses a case design similar to the original iPad Mini line. As a result, the tablet has thinner bezels on the sides of the display than the iPad 4.

DISPLAY

Both iPads feature a 9.7-inch IPS display with a resolution of 2,048 x 1,536 pixels and a pixel display of 264 ppi. The two also have great viewing angles. This means that the two iPads are tied as great for those who enjoy viewing videos or movies with other people.

PERFORMANCE

The iPad 4 is powered by a A6X Dual-Core processor, the same one used by the iPhone 5. Running with iOS 7, the tablet runs smoothly while delivering crisp and vibrant images.

Meanwhile, the iPad Air’s Apple A7 64-bit processor packs a lot of firepower. It is even said to be twice as powerful as the iPad 4’s CPU performance in terms of general processing and graphics.

Moreover, the Air is available for 16GB, 32GB, 64GB or 128GB of memory, while the iPad 4 can only reach up to 16 GB.

Although the iPad Air has the edge most of the time, the iPad 4 is still a viable option. If you’re an advanced user who wants a lighter and more portable body and a faster processor, then the Air is right up your alley. But if you don’t mind a basic tablet that performs well enough with a lower price tag, then the iPad 4 will do just fine.
