7. Multimedia Performance: PC Mark 2002

The mobile AthlonXP-1800+ CPU in the Evo tries hard. The low memory performance score confirms the poor marks from the Sisoft Sandra benchmark just run. The power of the hard drive is a typical notebook average.
The Sysmark 2002 application benchmark provides insight into the performance of the overall system. As the results prove, the dynamic switching of the clock rate/ voltage combination is very reliable in practice.

The power in outlet operation (AC) with different power schemes varies relatively little. Compared with the values supplied by a comparable notebook with an Intel mobile P4-m CPU , however, the values are well below expectations. This is not the processor's fault - rather, it is caused by the poor memory interface of the chipset. Still, these performance figures are adequate for everyday use.
Battery operation provides a good compromise between power and battery life when the "Portable/ Laptop" power scheme is used. Although the "Max Battery" setting yields an even longer battery life, performance is hobbled because of the rather low processor rate of 530 MHz in conjunction with the slow memory interface of the chipset. Typical office applications, however, can still be carried out efficiently.
