With the launch of iPhone 5S, Apple has become the first company to introduce 64-bit computing for smartphones. This development has long-term implications not only for Apple, but also for other key participants in the smartphones and tablets ecosystem – companies like Google, Microsoft, Qualcomm, Samsung, and Intel.
Why 64-bit: All smartphones, except iPhone 5S, and the majority of tablets at present run on 32-bit operating systems (OS). Moving from 32-bit to 64-bit is like doubling the number of lanes on information superhighway. For current smartphones applications, 32-bit is plenty. But 32-bit will eventually run into a bottleneck for applications needing more than 4GB dynamic RAM memory. This limitation is easily removed with 64-bit OS. PCs and Macs moved from 32-bit to 64-bit some years ago. That is the future for smartphones and tablets running data-intensive applications.
