11. System Performance: Sysmark 2002

As the results show, the system performance suffers considerably if the clock speed of the Celeron M is restricted to a value of approximately 300 MHz by means of the BIOS settings shown in the previous section. However, for standard office applications such as word processing or spreadsheet calculations, a performance value of 35 points is more than enough.

Battery Test: Mobilemark 2002

It is interesting to see how the Celeron M system competes with the Pentium M notebook with regard to battery life.

Just a reminder: The Celeron M always runs at maximum clock speed, in contrast to the Pentium M. In addition, its power loss in the "Sleep" and "Deep Sleep" sleep modes is approximately 30% higher compared to a corresponding Pentium M CPU.

The Mobilemark results impressively prove the power savings theory. With the Pentium M CPU, there is a good hour more battery life under normal conditions.

However, if you freeze the clock speed of the Celeron M at 300 MHz, the battery life's edge is reduced by almost half (compatible mode). Of course, it must also be noted that in a Celeron M system, the system performance in this case also drops by 25%.
