Multitasking: Scenario 3

Scenario 3

The third and last scenario in multitasking testing is based around someone gaming on their machine.  Most gamers don’t have a whole lot of active applications running behind their games, so I didn’t include anything like the PDF or Excel document in the background.  What I did include was Trillian, iTunes (as I know many gamers listen to MP3 while playing their games) and I also threw in a Norton AV virus scan.  While you may not have Norton do a scan on purpose while you are gaming, many times I have had NAV start doing one based on its schedule while I have been doing other things, so I felt it appropriate for a worst case scenario.

  1. Open Trillian
  2. Open iTunes and play 12 song playlist
  3. Start NAV virus scan on HDDs
  4. Start Doom3 and run timedemos @ 1024×768, HQ, 4xAA

The results this time were based around the average frame rate reported by the Doom 3 in-game time demos.

At 1024×768 with 4xAA and in High Quality mode, the difference between the three processors is actually already pretty slim:  less than 6 FPS separate the top from the bottom results.  Let’s see what happens when we add in some background work into the mix.

The Athlon 64 X2 4400+ does see a gain in its lead with both iTunes and Norton AV at work in the background, as the lead has gone from about 6 FPS to 9 FPS.  Still nothing very exciting but its important to see where this progresses as newer games come out that have any kind of multithreaded capability in the engine.
