Intel Mobile Pentium 4 3.06 GHz
The 'Mobile Pentium 4' is basically a desktop CPU that was sold as 'mobile' CPU. It was identical to the desktop version except for the so called 'Enhanced SpeedStep' feature. This feature allowed to reduce the multiplier and voltage while the CPU was idle (a feature seen on any regular desktop and mobile x86 CPU today).
This particular CPU was made in the 10th week of 2003 which is roughly three months before the CPU was officially released.
