It is no secret that the core purpose for the Galaxy S6, release date of which is rumoured to come as early as January 2015, is for Samsung to better compete with Apple's iPhone 6 and propel the South Korean tech giant back to the top of the global smartphone market.

But the big question is - will Samsung deliver this time around and deploy with the Galaxy S6 the essential functionalities that will boost its chances of upending the market leader that is the iPhone 6?

In a report by The Motley Fool, the S5 replacement appears to be the monster device "that will outclass (both) the iPhone 6 and 6 Plus." Specifically, the same report indicates that the Galaxy S6 will shine in three key areas:

Higher RAM provision and latest technology

The minimum expectation is for the Galaxy S6 to overtake the specs and capabilities that Samsung had presented with its twin 2014 flagships - the Galaxy S5 and the Note 4. One possibility that is gaining ground is a variant of the GS6, likely the international build, will flash the Snapdragon 810 processor by Qualcomm.

That happening will mean that the next Galaxy flagship is very much open for supersized spec upgrades, the most notable of which will be felt in the random access memory department or RAM.

It will be hardly surprising that with the Galaxy S6, Samsung will jump from LPDDR3 to LPDDR4 and the upcoming device will boast of at least 3GB of RAM with the high likelihood of higher provision once the phone is out of the box - 4GB perhaps.

Efficiency, however, is the most exciting benefit that the GS6 will get from the LPDDR4 memory technology. That would mean the device is equipped with extreme mobile powers not found on any of the iPhone 6 models plus one welcome bonus - the Galaxy S6 will not be a power-hog, promising single-charge battery juice that could last more than 24 hours even in extensive usage.

Superfast Internet access

The Note 4, according to The Motley Fool, is already a powerhouse in terms of LTE speed and clearly outperforming any of the iPhone 6 and 6 Plus in mobile download speed. It's only natural that the Galaxy S6 will do significantly better, likely leaving the Apple hero phones behind by many miles.

Again with the Snapdragon 810 powering up the next Samsung pride, it will likely sport a cellular radio signal that is governed by the Category 9 LTE-Advanced technology, which translates to maximum speeds of 450 megabits per second (MBPS) for download and 50MBPS for upload.

...and breakneck Wi-Fi speed

Complementing the Galaxy S6's LTE edge over its rival is a Wi-Fi standard that will deliver download top-speed of 650MBPS. This is made possible by Broadcom's BCM4358 that takes full advantage of the latest Wi-Fi 2x2 802.11ac solution.

The chance is quite high that the chip - or even a much better version - will find its way to the Galaxy S6 as the same is already showing prowess via the Galaxy Note 4, The Motley Fool noted on its report.

Additional come-ons for the device is a freshly-engineered body - light and slim - and Samsung's unique TouchWiz render of Android 5.0 Lollipop, which suggests it will be first Samsung kit to get a solid taste of Google's latest mobile operating system.

And if indeed Samsung is so raring to take on the iPhone 6 with the Galaxy S6 then the latter could be really set for a release date anytime in January 2015 with the grand introduction to be packed with the CES 2015 in Las Vegas that will kick off on the 6th of the month.
