Recently you might have heard of 64-bit smartphones and the fact that Android L now supports 64-bit architecture. For those not familiar with the term and don’t know what 64-bit is, we are going to take a look at why you should care and why there is such a huge difference between a 64 bit and non 64 bit smartphone.
64-Bit is the size of the data types that it handles and the size of its registry, the bigger the more data types it can handle. Currently all Android smartphones are 32-bit while Apple’s iPhone 5S is already 64-bit. 64 Bit can access over four billion times as much physical memory than a 32-bit processor
3 Advantages of having a 64-bit CPU vs 32-Bit CPU smartphone
- Lower Power consumption: Battery running out too fast? With a 64-bit processor power consumption is much lower. Power Consumption is lower due to less CPU load and reduced calculation time.
- More Memory: 32-bit CPU’s can only handle 4GB of RAM while 64-bit doesn’t have this limit
- Complex Encryption. Improved Security: 64-Bit can process incredibly large numbers allowing you to better encrypt data against unauthorized access.
Why 64-bit is not just a marketing gimmick
Some of you might think that it is just a marketing gimmick, similar to how Amazon’s Fire Phone has is “3D” but the thing is, 64-bit is not a marketing gimmick. The improvements over 32 and 64 bit is huge with better register efficiency, floating points instructions and memory addressability.
What about gaming? How does 64-bit affect Gaming on mobile devices?
Remember 8-bit games? A limit amount of pixels and colors were available and as games started progressing, 16-bit and then 32-bit color games started to appear. So does 64-bit mean that there are also more colors? Well yes, but this doesn’t mean graphics improve, it is a small change that you will most likely not even notice. The point is that increasing the bit depth of the processor allows you to do new stuff, but it has no effect at all on the basic speed of a CPU or its ability to run existing code
The Downside of 64-bit
While 64 bit doesn’t have a real big advantage over anything it is more the adoption rate of the architecture. In order to make the most out of 64-bit, apps that use native library in the Google Play Store will have to be optimized or will run at the same 32-bit speed they are currently doing. Once 64-bit Android L Smartphones start to appear it will still take some time to optimize apps for the new architecture.
