As usual, we will first run synthetic benchmarks.
The SiSoftware 2007 suite features an updated enhanced-functionality interface, runs on three platforms (Win32 x86, Win64 x64, WinCE ARM), contains 13 tests, 34 informational modules, and supports a large range of devices thanks to the developer’s collaboration with Intel, AMD, ATI, SiS and VIA. The program is supported in six languages and has a free Lite version for personal and educational purposes.
PCMark 2005 carries on the tradition of complex benchmarks of the series and uses fragments of real-life applications as tests. This makes it somewhat more relevant for end-users as opposed to fully synthetic benchmarks. After running a series of 11 tests on the different components of the system, the program calculates an overall performance score in units called PCMarks. PCMark 2005 can check out a computer at processing HD video and encoding audio, and offers enhanced tests of the CPU and hard disk under multi-threaded load. The overall score is calculated by the formula: PCMark Score = 87 x (the geometric mean of the basic tests) , where the geometric mean is calculated as (Result 1 x Result 2 x…)/the number of results.
SiSoftware Sandra measures the overall performance of the system as well as that of each of its subsystems, while PCMark benchmarks the computer performance in office and office-related applications and also produces performance scores for the main subsystems (CPU, memory, graphical, and disk subsystem).
The CPU performance tests produce expectable results, which are proportional to the frequencies of the installed CPUs. When the notebooks switch to their batteries and enable Max Battery mode, their CPU clock rates are reduced to the minimum of 1GHz. The results become almost identical then. The memory subsystem of the ASUS Lamborghini VX1 is somewhat faster as it incorporates two times the amount of memory installed in the Dell Precision M90. Both notebooks feature dual-channel memory access. The amount of memory is not crucial in the graphics subsystem tests, however, and the mobile workstation easily beats the rather powerful Nvidia GeForce Go 7400 VX with TurboCache technology which allows to allot up to 512MB (that’s the amount of dedicated graphics memory the Nvidia Quadro FX 2500M is equipped with in the Dell notebook) for the needs of the graphics subsystem.
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 evaluates 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 following table and diagrams show the outcome of these tests:
It is all clear here. PC Magazine’s benchmarks put a high load on the CPU and the ASUS Lamborghini VX1 has somewhat better results thanks to its higher CPU clock rate. When working on the batteries, the notebooks lower their CPU clock rates to the same point and produce similar results as a consequence.
