Doom 3 Alpha Leak Results
We thought it might be interesting to include benchmarks under the Doom 3 Alpha which leaked its way onto the Internet a couple of weeks ago. We tested using graphics "r_mode 5" (1024x768 32bit color) using the command "timedemo activate_demo1.demo".
The results under Doom 3 surprised us quite a lot indeed. As you can see, there was only a very small margin splitting the two systems with SpeedStep making hardly any difference whatsoever.
Unreal Tournament 2003 Results
UT2003 is one of the newest DX8 installments to our benchmarking suite. It serves as a good comparison since it makes use of quite a few shaders under DX8.1 which help stress the system out and provide us with a good benchmark. We used the included benchmark program and divided Flyby and Botmatch results to give you a rounded result to one decimal place at each resolution.
At 1024x768, the desktop system had a clear advantage. However, as we start to push the resolutions up, the differential between the desktop and mobile systems start coming more in line with each other. The Dell Inspiron 8200 was able to handle gameplay under UT2003, with ease - which was a shock to us at first.
Oddly enough we saw that with SpeedStep enabled under UT2003 our results showed that it was actually considerably faster than with SpeedStep disabled. We are not sure why this is the case, UT2003 may have improved SpeedStepping support - but we cannot be 100% sure.
nVidia ChameleonMark Results
ChameleonMark is a performance tool for measuring pixel shader performance for a variety of shaders. It is based upon the popular "Chameleon" demo released by NVIDIA with the introduction of the GeForce3 line of GPUs many months ago.
Again at 1024x768, the desktop system had quite a lead over the mobile system. When we start to up the resolution, the results become closer. We can see in this benchmark that with SpeedStep enabled, it does not have a considerable affect over performance results.
