Performance

As usual, we will first run our 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 and 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. SiSoftware Sandra measures the overall performance of the system as well as that of each of its subsystems.

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). 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 a computer out 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…) divided by the number of results.

Being equipped with identical Intel Core 2 Duo CPUs, the notebooks have very similar results in the CPU tests. The numbers are lower in the battery mode because the CPU clock rate is then reduced from 1.66GHz to 1.0GHz to save power. Strangely enough, the two memory subsystems differing in the frequency and amount of memory produce similar results irrespective of the power mode.

As for the graphics subsystems, the NVIDIA GeForce Go 7400 installed in the VAIO VGN-C2ZR/B is claimed by the manufacturer to be somewhat faster than its namesake installed in the VAIO VGN-FE31HR and this is confirmed by the test results. The exclusive graphics solution behaves differently when powered by the battery. It tries to save more power and slows down dramatically in the battery mode, resembling ATI’s mobile solutions in this respect. We’ll see this in the graphics tests below as well.

In the disk subsystem tests the SATA drive enjoys an obvious advantage over the ATA model.

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:

The Winstone benchmarks show a small advantage of the VAIO VGN-C2ZR/B over the FE series model because the former has more system memory. The results are lower in the battery mode proportionally to the CPU frequency reduction.
