The notebooks both have discrete graphics cores, NVIDIA GeForce Go 7400, we tested them in three versions of 3DMark: 3DMark 2003 3.6.0, 3DMark 2005 1.2.0 and 3DMark 2006 1.1.0.

3DMark uses its own rendering engine to create a set of 3D scenes that load the graphics subsystem in various ways. Compared with the previous version, 3DMark 2005 uses Shader Model 2.0x/3.0 instead of Shader Model 1.x, provides full compatibility with Shader Model 2.0, includes more complex tests (over a million polygons per each frame), and employs normal maps. 3DMark 2006 brings support for HDR, Uniform Shadow Maps, and multi-core CPUs. It is overall oriented at Shader Model 3.0, but two out of its four graphics tests work within the Shader Model 2.0 framework.

The two notebooks are equals in their 3DMark results. The graphics subsystem of the tested notebook seems to be faster in some subtests, but this is far from an overwhelming advantage. When powered by the batteries, the GeForce Go 7400 installed in the VAIO VGN-C2ZR/B slows down as much as ATI’s graphics solutions.

Next, we tested the notebooks in two modes in Quake 3:

  • 640x480; 16 bit; Vertex Lighting; Low Detail; 16-bit Texture Quality; Bilinear Texture Filter
  • 1024x768; 32 bit; Lightmap Lighting; High Detail; 32-bit Texture Quality; Trilinear Texture Filter

And in one mode in Quake 4:

  • Overall Quality – High; Resolution – 1024x768; Format – 4:3; Multi-core Optimization – Yes. Other settings were left default

There was no standard demo record in Quake 4, so we had to create one by ourselves. We will use it in every review of notebooks on our site so that different notebooks could be compared under identical conditions.

We see the same overall picture in these graphics subsystem tests. The VAIO VGN-C2ZR/B with all its megabytes of dedicated memory behaves just like a regular GeForce Go 7400. So, you can indeed play 3D games on this notebook, but its performance is going to be much lower when you switch to the battery.
