Hi Guys!

Unfamiliar with What the Tech?!! Series? Well, check out the previous issues below:


Welcome again to What the Tech?!!
December! Ah, Yes, the season of giving gifts and receiving too. And if you're a techie, It's also the time of the year when mostly you plan to buy yourselves a new gadget or a new Android Smartphone.

So with that in mind, lets begin with Issue #4

What the TECH template christmas.jpg

Android is on a full scale expansion. Starting from Android 1.0 to cupcake then now to Lollipop, Android had a long run of bettering performance and expanding features. Alongside the OS, manufacturers have really caught-up with their hardware. Starting with the first Android Phone,  T-mobile G1, which was released in 2008 only have a measly 528 Mhz Single Processor and 192mb of RAM, but now our high-end phones have Octa-core processors and 3 gigs of RAM. Android did really came a long way to stardom.

And yet still, now at the later part of 2014, we've seen another milestone for the Android Ecosystem: 64-bit computing. The HTC Desire 510 holds the crown as the first 64-bit Android Smartphone running on the new mid-range Qualcomm Snapdragon 410. But since then, many other OEM's have also anounced their own 64-bit phones.

nvidia-tegra-2-dual-core-mobile-processor.jpg

While nearly all mainstream laptops and desktop CPUs transitioned to 64-bit many years ago, it's just recently that Android caught up with 64-Bit, with the recently released Android 5.0.

So why is there a need for a transition from 32-bit to 64 bit processors? What's a 32-bit or a 64 bit means anyway? Why should it matter to you? the future is bright for the new 64-bit architecture, and starting 2015, its going to be the rise of the 64-bit Android Environment.

Let's Get Started!

32-bit? 64-bit? x86? x64? ARMv8? WHAT THE TECH?

----------------------------------------------------------------------------------------------------------------
What's 64-bit computing?

Well, I'm not expecting that all of us would really understand all of these terminologies and stuff, But let me only indulge you with it's real-life implications.


3 factors would have to be taken into consideration here : HARDWARE, OS, and APPLICATIONS


64-BIT HARDWARE:
What's new?

1. New 64-bit ARMv8 processors & Intel x64 Atoms vs. current ARMv7

While Intel has long implemented 64-bit processors, ARM has only recently did.

According to the ARM website:
ARMv8-A introduces 64-bit architecture support to the ARM architecture and includes:
64-bit general purpose registers, SP (stack pointer)  and PC (program counter)
64-bit data processing and extended virtual addressing.

For Android, the story is not simply 64-bit, but its really more about the new ARMv8 Processors. Previously, most Android Phones (except Intel-based Android) runs ARMv7 processors (Qualcomm, MediaTek, Exynos, etc.) But with the new ARMv8 Architecture, in addition to enabling 64-bit applications, it should bring improvements in power efficiency as well as performance impact on nearly every 32-bit Android applications.

Exynos_5433_AnTuTu_Benchmark.jpg

2. Larger RAM support
One big thing that we can expect with 64-bit processors is the maximum amount of memory (RAM) that it can support. 32-bit only support a maximum of 3-4GB of memory (that's why even the highest-end of phone is only with 4GBs of RAM), but 64-bits can support memory over 4 GB. This is definitely beneficial for APPS that will use more resources in the future like Console-grade Android Games, etc.

-----------------------
64-BIT OS: ANDROID LOLLIPOP vs. 32-bit Android (Kitkat below)

For Android to take Advantage of the 64-bit hardware, it has to upgrade their OS to 64-bit as well. Thus the Introduction of the Android 5.0. But, Without Android 5.0, 64-bit processors would make an inch of a sense.

Lollipop-2-590x330.jpg

There's nothing much to be said on Android's 64-bit upgrade. 64-bit computing won't matter that much for now.

------------------------

APPS ON 64-BIT PLATFORM: BACKWARD COMPATIBLE

According to Google, building 64-bit apps starting Android L will offer them increased addressable memory space, a larger number of registers, and new instruction sets.

But I think that what we should address here is that 64-bit is able to run 32-bit the same way.

Look at the Charts below:

32 bit table.jpg table 2.JPG

So even if we all moved up to 64-bit devices, our favorite Apps will still run just fine.

--------------------------------------------------

Now here's our question for Buying a Smartphone this Season:
Should I avoid buying a high-end 32-bit Smartphone and instead buy a new 64-bit one?

Definitely Not!
While 64-bit is new, and have some improvements, your 32-bit phone (like MI3 or MI4) will still outperform most 64-bit offerings. Having a 64-bit processor won't make you phone any faster at all. You won't really be seeing a huge improvement in the performance of your NOTES app (for example) due to the new architecture.

However, things that are graphics intensive and require a lot of operations on pixels and color data, physics calculations, etc. will surely benefit greatly because these are large processes being operated.

How about Xiaomi and MIUI? Any 64-bit offerings anytime soon?

There's no official plan released by Xiaomi as of yet, but there are RUMORS and leaks concerning Xiaomi Releasing 64-bit MI's:


As with our beloved MIUI, Lollipop is definitely at their Roadmap, but as now, there's nothing conclusive.

miui lol.png


However, Hugo Barra talked about Android Lollipop in an Interview with @raviki
Q: What are Xiaomi's plans for rolling out Android 5.0 Lollipop across its range of mobile devices?
Barra: Upgrading to Lollipop is my #1 priority from a product perspective for our global business. As you know, we customize Android significantly and have our own design language — so what we're tasked with now is not only all the technical aspects of putting Android 5.0 on our devices, like at the kernel level, but we also have to marry Google's Material Design language with ours.
-------------------------------------

So there you have it folks!

Now you know WHAT THE TECH is 64-BIT ARCHITECTURE all about!
----------------

Always remember: Don't be ignorant. Be smart, Be informed.

This has been Iakwbos, now signing off.


Thanks to @Meredith, @Penguin, and to all our team members at QQ for their invaluable support and encouragement. Special thanks to our ever helpful  team leader @iyengar for his utmost support!

RESEARCH SOURCES:
Without these sources, i would not have gathered the right information for you:

Now which Android Device will you choose to buy next: stay with 32-bit, or jump in to 64-bit? Join the debate below!

I'm not going to jump ship as i don't believe the apps in store is optimized to function at that level as in yet. Would take time around 3-4 years and we would have some thing else to think about.

64-bit is still in its early implementation. So 32-bit is still the way to go! Its' not going anywhere anytime soon.

What happened to computers several years ago will happen to androids now...
64 bit is the future, while 32 bit will be slowly left out.
