Intel's mobile version of the Pentium Dual-Core, or otherwise said, Intel's budget version of the Core 2 Duo Mobile.

The Pentium Dual-Core Mobile is technically a Core 2 Duo but uses a slower FSB (QDR533 opposed to QDR667), has less L1-cache and doesn't have Speedstep functionality. The latter is used to decrease power consumption. Speedstep lowers the multiplier (and thus clock frequency) and the core voltage.
