Design
-
Intel designs and designates the Core 2 Duo and the Pentium as dual-core processors. This means that they have two processing units.
Speeds
-
Both the 2 Duo and Pentium chips have a 3.33-gigahertz peak in terms of clock speed, which is the rate at which the processors perform their basic functions. The 2 Duo, however, can bottom out at 1.8 gigahertz, while the Pentium goes lower at 1.6 gigahertz. Also, while the 2 Duo and Pentium share the 800-megahertz minimum regarding bus speed (the rate at which the processor connects with the computer's motherboard), the 2 Duo has a higher peak at 1,333 megahertz, with the Pentium peaking at 1,066 megahertz.
