As widely expected, Intel says it is adding 64-bit features to the standard Pentium line, following AMD's lead.
"Intel's 64-bit extension technology will be software-compatible with AMD's 64-bit extension technology, Barrett said. A few architectural differences won't affect application compatibility, he added. The first Intel chip to take advantage of the 64-bit extensions technology will be one code-named Nocona, the next generation of the Xeon DP processors for workstations and low-end servers. Nocona is scheduled for release in the second quarter," reports the IDG News Service.
"Future versions of both the Prescott processor and the Xeon MP processor will also include this technology. Prescott is the core for existing Pentium 4 CPUs."
There will be more details later today. [Update] See here
