The first feature has been the subject of persistent speculations in the past weeks that again gained some sort of confirmation from ARM, which is the processing technology that Samsung will reportedly employ.
The retina scanner, on the other hand, is hinted in a new Samsung patent application documents that Patent Bolt picked up and published this week.
Together, these likely Galaxy S5 features make for a very powerful gadget that Samsung is supposedly putting together for a first quarter unleashing in 2014, possibly pre-empting the iPhone 6 rollout from Apple.
With 64-bit computing capabilities on board, the GS5 is fast developing into a beastly handset that Sammy watchers are dreaming it to be. The powerhouse has been earlier implied by a senior Samsung executive and this week, it becoming real gained further traction.
From South Korea, The Korea Herald reported that Samsung and processor chip designer ARM held a meeting that touched on 64-bit chip technology that will be geared for deployment with the Galaxy smartphone lines in 2014.
There was no specific mention of the Galaxy S5 or any other planned Galaxy models but the report cemented the notion that one of the major upgrades to expect from the Samsung device is a CPU in the 64-bit class.
Note that shortly after Apple has unwrapped the A7-powered iPhone 5S, the Asian tech giant declared that 64-bit standard is also making its way to high-end Galaxy devices.
The Galaxy S5 then will boast of "improved power and speed," should the report turned out to be true, Gotta Be Mobile said in a report.
And to complement such impressive gadget muscle is a killer security feature that is comparable to the Touch ID fingerprint scanner that Apple has showcased with the iPhone 5S.
It is biometrics but Samsung's take uses iris scanner technology for its core authentication mechanism. According to Patent Bolt, "iris scanning is used to collect information of characteristics of respective attributes of irises of people and use the information in authentication technology for security."
The system is deemed better than fingerprint sensor because it processes biometric data faster and is non-contact, therefore easier for gadget users to adapt to. "Iris scanning is being evaluated as a biometric identification technology more advanced than a fingerprint or retina scanning technology," the same Patent Bolt report said.
In practical embodiment, retina scanning is made possible with the use of front camera that will work in tandem with iris and proximity sensors. The principle is quite similar to the Smart Stay and Smart Scan features that Samsung has introduced earlier this year with the Galaxy S4.
This provides a solid clue that the feature would be readily available in time for the rumoured Galaxy S5 release date, which is pegged by analysts to happen between January and March 2014.
