Intel has started delivering 64-bit processors to server and workstation OEMs, but according to DigiTimes there is still no timetable for delivering the 64-bit Pentium 4's to the desktop segment.
There has been increasing speculation about Intel’s plans for the 64-bit chips since the specifications and prices of Intel’s new Pentium 4 processors with 64-bit extension technology (known as EM64T) are similar to those of desktop CPUs, said sources at Taiwan motherboard makers.
The time is not yet ripe for positioning the 64-bit version of the Prescott processor for the desktop, stated sources at Intel Taiwan.
Taiwan motherboard makers commented, however, that Intel’s aim is to ease the relatively high inventory levels of its 32-bit processors before migrating the new chips to the desktop segment.
The 64-bit Pentium 4 processors are available at 3.2F, 3.4F and 3.6F GHz. Intel has added the letter F to distinguish processors that feature EM64T.
