I just saw an article that leads me to believe that Intel is going to come out with a 64 bit extension for the 32-bit Intel x86 architecture.
Intel President and Chief Operating Officer Paul Otellini on Wednesday said the world's largest chipmaker would likely give its 32-bit microprocessors an upgrade to 64 bits once supporting software becomes available.
"You can be fairly confident that when there is software from an application and operating system standpoint that we'll be there," Otellini said, responding to a question about 64-bit technology, in an interview with a Wall Street analyst that was broadcast over the Web.
Sounds like Intel will come out with something that is binary compatible with the AMD 64 bit extensions. Hmmm, IA64 looks more and more like IBM Microchannel every day.
