Gaming Multitasking Scenario 1: Heavy Downloading

In the first article, we ran under the assumption that gamers wanted to have as little running in the background while playing a game.  While that ended up being true for a lot of folks, we also received quite a bit of feedback asking for some pretty intense multitasking tests while gaming.  The requests were far more intense than even the most strenuous setup that we came up with, but because of the demand for such benchmarks, we spent some time putting a few together.  Note that this is by no means supposed to be an exhaustive comparison of all gaming scenarios. We are working on creating more and we apologize if your desired scenario didn't make it into this review, but keep sending in suggestions on how you play and we'll do our best to model some benchmarks after how you use your computer. 

The first test basically performs all of the tasks from our first Multitasking Scenario, with the exception of DVD Shrink.  We have Firefox loaded, but with all 12 tabs from the third test, iTunes is running and playing a playlist, and Newsleecher is downloading headers.  We kept Newsleecher in this test simply because it's the best way for us to be able to have a fairly CPU/disk intensive downloading task running in the background while still maintaining some semblance of repeatability.  So, replace Newsleecher with BitTorrent or any other resource-consuming downloading that you may be doing and you're good to go. 

Of course, Norton AntiVirus 2004 and Microsoft's AntiSpyware Beta were also running in the background. 

First, we ran our Doom 3 benchmark:

Gaming Multitasking Performance Scenario 1

The tables have now been turned. While the Athlon 64 held a 30% lead with no multitasking, it's now outpaced by both Intel processors, with the Pentium D holding a 25% performance advantage.

It's no surprise that having two cores yield less of a performance impact to having more applications run in the background.

Doom 3 was actually quite playable on both machines; although, loading the game and the levels took a lot longer on the A64, and there's a lot of stuttering during the actual game. 

The Pentium 4 platform was quite a bit better, but there is a definite reduction in performance.  Obviously, the Pentium D did the best out of the group, but you still notice the performance drop. 

Next, we ran the Splinter Cell: Chaos Theory benchmark:

Once again, the Pentium D is ahead of the Athlon 64, but the improvement in minimum frame rates is particularly impressive.  The Pentium D offers twice the minimum frame rate of the Athlon 64 in this scenario.

    the power consumption is a series mofo here.

    hm, with a P4 EE or PDEE, with 2 6800Ultra or GT, you're definitely expecting an oven case.

    Wonder how those dualcores overclock-->that should help to make up the single thread performance. On the other hand, Clearly HyperThreading is GOOD, but AMD still says NO.

    Great article. Well done guys.

    The only thing I have to question is how a dual core Athlon-64 at encoding. On the last page you say, "For encoding performance, you still can’t beat the Pentium D. Even a dual core Athlon 64 isn’t going to help enough in that area."

    What makes you think that when the 2.2 GHz Athlon-64 is RIGHT behind the 3.0 GHz Pentium 4 630?

    Everything I've read so far has told me that the Athlon-64 should scale better than the Pentium 4 as far as dual cores are concerned... so... what exactly are you basing your opinion that even a dual core Athlon-64 won't help in encoding???

    Does http://www.anandtech.com/cpuchipsets/showdoc.aspx?... page have an error?
    It lists the PD 3.2, P4 3.73 EE and the PD 3.2 EE, not the 3 CPU's montioned in the article. Wrong graph maybe.

    H isn't even near P on the keyboard...

    Holy crispy power and cook my eggs in true multitasking while I surf the net Batman

    I guess it makes sense that NCQ would help when multitasking. I assume that this would be the same on single cores as well? The new focus on responsiveness is a good move IMO. The time to switch between apps and redraw the screen and clicking on menus and buttons is what frustrates me when I am multitasking.
