On the eve of a new era of large-scale arrival 64 bit architecture to mobile devices, the company ARM spoke about the benefits of this technology.
Unfortunately, there is still some confusion among consumers about the benefits of 64-bit. When the 64-bit computers came from Intel and AMD have motivated its superiority in the ability to address more than 4 GB of RAM. Yes this is true, but it’s not the only benefit, in fact mobile is almost a huge advantage at all (at least for now). In fact, a huge amount of memory on the mobile device may not be as close.
Advantages of 64 bits for mobile devices can be found elsewhere.
Since 64-bit processors to move the data in 8-byte pieces, internally and externally, operations related to graphics, I / O, and Single Instruction, Multiple Data (SIMD) instructions allow to obtain a significant increase in speed in many problems. According to tests carried out on 64-bit implementation of ARM Apple, some operations are performed on 68 percent faster, and AES encryption 825%. It is noteworthy to note that some of these benefits were due to the support teams for cryptography in the new architecture ARMv8.
