With this article and the other about 64-bit technology from AMD, we finished to talk about the processors for the beginning of the millenium. In addition, it is important to mention that there already are computers running 64-bit versions of Windows and Linux. Now, more than performance, our biggest concern is the compatibility with our present programs. We really have to verify how much those 64-bit architectures are compatible with our 32- or 16-bit programs. We hope that in less than a year we already have the answer to this question. To finish this part of 64-bit CPUs, it is very good to see how the two companies compete on the market of high performance processors. This grants us access to even cheaper and better computers.

To conclude, we would like to comment the great space that there still is to the evolution of electronics and consequently to the evolution of computers. More important than the creation of supercomputers, this new age will see the permeability of the computers. It will be the time of invisible computers. They will be present in nearly all modern devices. At the moment they inhabit our TV sets, microwave ovens, cars, watches, stereos, DVD, etc… In a near future, they will invade the refrigerator, the toaster, the air-conditioner and all everyday appliances. We have gone beyond the cheap electronics age and we are entering the cheap intelligence age.
