Intel Designs a 64bit x86 CPU?
Rumors abound that Intel is designing 64bit extensions to it's Pentium line, in case Itanium turns out to be a flop: "Intel's decision to back the novel Itanium architecture had upset a small group of Intel engineers in Oregon, who preferred to build on the x86 legacy. When AMD released the specifications of its upcoming 64-bit chips in the summer of 2000, these ``cowboy'' engineers decided that Intel needed to match its rival. They began developing their own 64-bit extensions to the Pentium line, making sure the code was compatible with AMD's design." Update: MercuryCenter has an article about this too.
