From his note:
We think the tablet will, at 7.5-8.0mm, be 15% thinner than iPad 4. The new device will likely be about 500 grams, or some 25% lighter than iPad 4, run on an A7X processor, and sport cameras with similar specs to the iPad 4’s (front HD, rear 5MP). The casing shape and color (silver and black) and narrow bezel design will be similar to the iPad mini’s.
Apple’s transition from the iPad 2 to the iPad 3 was an awkward one, quadrupling of pixels in the Retina display meant a thicker screen and a larger battery, which resulted in a much bulkier iPad. The dimensions and weight remained the same when Apple introduced the iPad 4, but with the fifth-gen iPad, the company’s using GF2 display tech, which is already used in the iPad mini, to reduce thickness and power consumption. Reduced power needs allow Apple to include a lighter battery, that saves up precious space:
We therefore think that iPad 5’s battery capacity will be 25-30% smaller, at 8,500-9,000mAh, than iPad 4’s, and the battery’s thickness will be 15-20% smaller, at 7.5-8.0mm, and the number of cells will be reduced to two from three.
Kuo added that the A7X chip powering the iPad would be manufactured on Samsung’s 28nm process node, contradicting earlier rumors of Apple moving from Samsung to Taiwan Semiconductor Manufacturing Company. Kuo says that the transition will be happening, just not right now.
Some rumors pointed to an April press event for the iPad mini and the iPad 5, but more than half of April has already passed and we’ve not seen any invites. This lends more credence to Kuo’s estimated launch timeframe of Q3 this year.
