The Real Test - AnandTech's Multitasking Scenarios
Shortly after receiving the dual core system from Intel, I posted a question in my blog asking AnandTech readers to respond with how they multitask. I kept the question pretty open-ended, just wanting to get a feel for all the different types of multitasking that this sample of AnandTech readers did on a daily basis. I then took the data and did my best to, in the limited time that I had, model some real world multitasking benchmarks based on the responses. The results are three real world, multitasking benchmarks with the promise of more to come.
The biggest commonality between responses was that AnandTech reader systems, much like my own, are loaded with applications running in the background. So, the first thing that I did to put together our multitasking testbed was to put a ton of applications on it, the type that we all use. I came up with the following list:
Daemon Tools
Norton AntiVirus 2004 (with latest updates)
Firefox 1.02
DVD Shrink 3.2
Microsoft AntiSpyware Beta 1.0
Newsleecher 2.0
Visual Studio .NET 2003
Macromedia Flash Player 7
Adobe Photoshop CS
Microsoft Office 2003
3ds max 7
iTunes 4.7.1
Trillian 3.1
DivX 5.2.1
AutoGK 1.60
Norton Ghost 2003
Adobe Reader 7
What's important about that list is that a handful of those programs were running in the background at all times, primarily Microsoft's AntiSpyware Beta and Norton AntiVirus 2004. Both the AntiSpyware Beta and NAV 2004 were running with their real time protection modes enabled, to make things even more real world.
With my system fully configured, I did what anyone else would do with a brand new system - I used it. I used it as an actual system doing real world everyday tasks and made notes of my impressions, then came the interesting part - I swapped out processors for a single core non-HT enabled Pentium 4 and started making notes of differences. Armed with the single core chip, I went to task on creating benchmarks based on some of the tasks that AnandTech readers did on a regular basis (not too surprising, I use my system in a very similar way to most AT readers). So let's get to the tests...

Drat. Double Post. Where's the gaming benchmarks? And are those multitasking scenarios realistic? I don't think I would ever do all that at once.Pandaren - Tuesday, April 5, 2005 - link

Additionally, what about throwing in Nero,DC++, azureus, bitcomet, and/or Power DVD. Just progs. that alot of typical college-aged users use(i can verify at least). Great article. Loved the multitasking analysis especially.sideshow23bob - Monday, April 4, 2005 - link

Anand, what about DVDDecrypt and DVDShrink at the same time (as in decrypting one movie, shrinking another)? Dual core could really make ripping faster if you could do both of those at once...ViRGE - Monday, April 4, 2005 - link
#44, SETI is a really good idea, not just because of heat but because it'll push the memory/FSB at the same time. If Intel's chips are getting choked, SETI should scream pretty loudly by tanking in performance.nigham - Monday, April 4, 2005 - link
Thanks, this was a real nice review and its got me all excited. One thing I'd really like to know, though, how does Linux handle dual-core? Does it show the same kind of multi-tasking performance boost that we see on Windows XP? I mostly use Linux for my work and I do a ton of multitasking. Windows I use only for gaming, which as you point out are mostly single threaded applications.gregwjones - Monday, April 4, 2005 - link
Dual-core benchmarks I'd like to see:Two instances of Seti@Home, BOINC version, run on a Pentium D 3.2GHz( dual-core, but no HT )
compared to Pentium 4 3.2GHz single core with HT.
Then run four instances of SETI@Home on the Pentium EE ( dual-core with HT ).
This should generate a lot of heat and put everything at max load.
I have a Pentium 4 Northwood with HT enabled and run two instances of BOINC Seti@Home while using the system to do everyday tasks.Like web browsing, DVD Decrypt, DVD Shrink. Everything is very responsive because BOINC runs at a very low priority.

Great article! It's a good thing you did not do a review like all of the other sites. With just some benchmarks and a few games.As always I can't wait to read more reviews form you Anand. :thumbsup;

The multi-tasking numbers are definetly intresting, but any sane person will wait and see what amd has up its sleeve.
