On October 22, Apple will present a trimmed down iPad 5 with a powerhouse processing chip and top-notch component upgrades but it is the Retina-toting iPad Mini 2 that will rule the charts after the devices' release date.

This is the consensus aired this week by numerous analysts, who are in agreement that the fifth-generation iPad has the alleged qualities to become another game-changer from Apple. It has been subjected to a major makeover, according to reports, leading to a profile that pretty much resembles that of the original iPad Mini.

Chris Whitmore of Deutsche Bank wrote in a note to investors this week that the iPad 5 bump ups will leave the tablet with upscale specs under the hood, headlined by a 64-bit A7 CPU, Touch ID fingerprint scanner and a massive battery that will extend the slate's operating hours.

In particular, A7 on the 9.7-inch iPad would allow the tablet to gradually match "the performance specs of the low-end of Intel x86 processor," Mr Whitmore was reported by CNET as saying.

Plus, a 4GB RAM provision will likely debut with the large-screen iPad since 64-bit computing standard enables its deployment, the Deutsche Bank analyst added.

On the other hand, the Mini 2, according to Amit Daryanani of RBC Capital Markets, will mostly reflect the same form-factor and a bit of power boosts that made the first edition a hot-selling item for Apple.

The smaller iOS 7 slate will rely on an A6 chip but will stun consumers with a high-resolution Retina display panel that will allow its 7.9-inch screen to flash a resolution of 2048 x 1536 with the same pixel density of the larger iPad.

The latter attribute plus a lower sticker price will make the Mini 2 a certified bestseller for the 2013 holiday quarter. "We believe the iPad Mini will likely drive higher sales relative to the 10-inch (iPad 5) refresh due to its attractive pricing," Mr Daryanani told Apple Insider.

The potential is high for the Mini 2 to significantly pad the fourth quarter revenue of Apple but there is major problem - production constraints, which Mr Daryanani said could lead to a serious supply shortage plaguing the Mini 2 global distribution.

In the event that Apple is able to ship out sufficient Mini 2 supplies, the smaller iPad will dominate its bigger brother in terms of sales percentage by the end of December 2013, likely securing 65 per cent of the pie.

That means that for each unit of iPad 5 that leaves the shelf, two or three iPad Minis will fly off from November through end of December, the RBC analyst said.

Release date for both the iPad 5 and iPad Mini 2 with Retina is seen to happen in the immediate weeks or days after the Oct 22 Apple event though some analysts warned that the Mini 2 would not materialise until December this year.
