Next, I 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

The low resolutions employed in this test allow the notebooks to show their overall best rather than the worth of their graphics subsystem alone. The second-generation DDR SDRAM looks better here. When powered from the mains in the second test mode the ATI Mobility Radeon X700 leaves the Nvidia solution behind for the first time. The results of the notebooks working on their batteries agree with the results of the previous tests.

The Nvidia GeForce Go 7400 beats the ATI Mobility Radeon X700 in the last graphics test, too. Summing it up, the ASUS Z83Db is quite a gaming notebook, but only when powered from the electric mains.

The notebook’s battery life was measured with Battery Eater Pro 2.60. It is going to show if such aggressive power-saving methods applied to the CPU and graphics core are justifiable. The test was performed at the maximum screen brightness in the following modes:

  • Classic (the system bears the maximum and evenly distributed load)
  • Reader’s test (the pages are scrolled through each 15 seconds)
  • DVD mode (the DVD movie was launched in Battery Eater’s Idle test mode)

Well, the aggressive power-saving doesn’t seem to be fruitful because the ASUS Z83Db cannot last long on its battery. Its battery life can hardly suffice even to allow you to watch a full-size DVD movie. So, its battery may be considered as an uninterruptible power supply rather.

Here are the battery discharge diagrams for the different operation modes:
