General Computer Science II - 64-bit processor - Architecture Introduction: To get a first idea, how the 64-bit architecture works and also how it differs significantly from a 32-bit implementation it is useful to consider one definition first: "A 64-bit processor is a microprocessor with a word size of 64 bits , a requirement for memory and data intensive applications such as computer-aided design (CAD) applications, database management systems, technical and scientific applications, and high-performance servers. 64-bit computer architecture provides higher performance than 32-bit architecture by handling twice as many bits of information in the same clock cycle ." ( search390.com ) The most important parts, which define a 64-bit architecture are boldfaced and give a rough idea that one can now process not only 2^32 = 4294967296 basic units of information, but 2^64 = 18446744073709551616 units. The numbers are quite impressive and show that the architecture level has to be updated accordingly.
