- The address of the long double data will cause no less detrimental to the design of computing systems. Imagine a network of natural changes now start each 20-digit phone number you'll see. - Not quite as bad, but like the example above, if the sum of 12 + 34, CPU registers Longer advantage, but if the calculation is 1 + 2, why? This time the two CPUs 32-bit and 64-bit are the same speed alone. - The trouble with software: Software CPU who ordered what. 12 + 34 as the example above, the 32-bit software will make the CPU perform 1 + 3, 2 + 4, then transplant results back. 64-bit software will protect computer CPU straight 12 + 34 always. You will see that if the 32-bit software running on 64-bit CPU 64-bit operating system, it still runs well, though not optimal. But if the 64-bit software, it will not be able to operate with the CPU or 32-bit operating system. This is why Microsoft and many development studios to make two versions of the same software. For example, Windows 7 and Windows 8 32-bit and 64-bit; Microsoft Office 32-bit and 64-bit. - For mobile devices, this will cause the app maker hesitate to write applications for 64-bit processors, because it will only run on a very small number, at least as of the moment. But if they just wrote for the 32-bit app, it will not take advantage of 64-bit CPU. Therefore, as well as on the PC, if developers want their app optimized for 64-bit, it must make two different versions, and takes time, effort and money than a lot of maintenance and upgrade later. 64-bit applications on the mobile device As mentioned above, 64-bit processor has proven capability and its benefits to PC, the PC and the server or supercomputer sized to count. CPU 64-bit computers will help take advantage of the above 4GB RAM, which has become extremely popular today. Many machines also spend 6GB, 32GB and even more there. 64-bit architecture also helps applications faster data processing (or in other words is faster), and can clearly see this effect in the massive alum to editing software, 3D image rendering, programming, databases, ... current 64-bit CPU has also appeared on the market a lot. Most of Intel Core i, Celeron, Pentium, the APU and CPU AMD line are 64-bit chips. 64-bit operating systems, both Windows, OS X, Linux have both, and we also use them a lot for about 3 years now. Future Intel chips will also support 64-bit Android's.
