New technologies are always becoming old ones with the passage of time and the development of improved versions. This holds true for computer components, particularly central processing units or CPUs. Next generation CPUs always follow a downward path from fame. With the release of a new line of CPUs, the old “next generation” CPUs become standard CPUs and are eventually rendered obsolete.
One important development in CPU technology is the upgrade from 32-bit processing to 64-bit processing. A 64-bit processor was made possible with the release of the dual core and multi-core processors. Intel’s Pentium D dual core processor and its big brother, the Core 2 Duo dual core processor, were released just one year apart that many are unable to tell the difference between the two.
