Besides SYSMark2004 SE that uses mostly desktop working scenarios, we have also resorted to a special MobileMark2005 benchmarking suite to measure the performance of our Centrino Duo platform. This benchmark works with a user model more typical of mobile conditions. In this case there are the following applications used: Microsoft Word 2002, Microsoft Excel 2002, Microsoft PowerPoint 2002, Microsoft Outlook 2002, Netscape Communicator 6.01, WinZip Computing WinZip 8.0, McAfee VirusScan 5.13, Adobe Photoshop 6.0.1 and Macromedia Flash 5. The benchmark emulates the work model of a car dealership employee who creates and edits documents in Microsoft Word, Excel and PowerPoint, works with an e-mail client, and uses Photoshop and Flash to edit images and animated files for his presentation. He also actively uses the Internet browser and a few additional tools such as archiving utility and antivirus software running in the background.
I would like to specifically stress the fact that MobileMark2005 test is put together in such a way that it measures the performance when the notebook is running on battery. In fact this is not surprising at all: this work mode is much more typical of the notebooks that we are looking at today. Note that during this test session all power saving technologies available in the given platform are activated. Therefore, the numbers given below also take into account the negative effect of Enhanced Intel SpeedStep and Intel Dynamic Power Coordination that slow down the system performance.
The funny thing is that the diagram shows a completely different picture compared with what we have already seen in SYSMark2004 SE. However, this shouldn’t be puzzling for you: there is a logical explanation to any phenomenon. On the one hand, the tested Centrino Duo platform is equipped with a slower processor (from the clock frequency standpoint) than the Centrino platform. On the other hand, the typical notebook usage scenarios (when the notebooks are not used as desktop replacements) are very rarely using heavy applications with multi-threading optimizations and do not really take advantage of operating system multi-tasking. Moreover, MobileMark2005 models the work in relatively old versions of popular applications that have been mostly developed without taking into account the things contemporary processors are capable of.
