As usual, I will first run synthetic benchmarks.

SiSoftware Sandra 2004 measures the overall performance of the system as well as that of each of its subsystems, while PCMark 2004 benchmarks performance in office and multimedia applications and also produces performance scores for the computer’s main subsystems (CPU, memory, graphical, and disk subsystem).

The advantage of the dual-core architecture is expectable and big. It is also expectable that the results are more than by half lower when the notebooks work on their batteries. The frequency of the AMD Turion 64 MT-34 is reduced by 1GHz in the Max Battery mode whereas the bottom frequency of the Intel Core Duo processor is 1GHz (it is reduced by 0.83GHz). The ATI Mobility Radeon X700 looks much better than the Nvidia GeForce Go 7400 when powered from an AC power source, but slows down dramatically as soon as you disconnect the notebook from the wall outlet. This is a typical behavior of ATI’s mobile graphics solutions, though. The difference in the memory subsystems is noticeable, too. The second-generation DDR SDRAM is faster and more economical (the tests don’t show that, but you should be aware of that difference, too).

The Business Winstone 2004 test runs scripts of the following real-life office applications, several scripts at a time to simulate multi-tasking: Internet Explorer, Outlook, Word, Excel, Access, Project, PowerPoint, FrontPage, WinZip, and Norton AntiVirus Professional Edition.

The Multimedia Content Creation Winstone 2004 test determines the performance of a computer in the following multimedia applications: Windows Media Encoder, Adobe Photoshop and Adobe Premiere, NewTek LightWave 3D, Steinberg WaveLab, Micromedia Dreamweaver MX, and Micromedia Director MX.

The benchmarks from PC Magazine are not optimized for multi-threaded processors, and the ASUS V6X00J has DDR2 SDRAM. The results of the two notebooks are proportional to their frequencies in the two power schemes. Switching to the batteries, the notebooks lose in performance as much as they lose in CPU frequency, and the ASUS V6X00J whose CPU frequency is 0.2GHz higher is preferable to the ASUS Z83Db then.

The contending notebooks are equipped with discrete graphics cores, ATI Mobility Radeon X700 and Nvidia GeForce Go 7400, so I only benchmarked them in 3DMark03 3.60.

3DMark uses a set of 3D scenes rendered by its own graphics engine to check the capabilities of a computer’s graphics subsystem.

The ATI Mobility Radeon X700 shows its best at first, but loses all its advantage as soon as you disconnect the notebook from the electric mains. That’s how ATI’s power-saving method works. Switching to the battery transforms the ASUS Z83Db from a gaming computer into a rather weak opponent to the ASUS V6X00J.
