Multitasking Scenario 2: File Compression

For our next test, we simulated what would happen if we performed two disk intensive tasks at the same time: zipping a file while importing a 260MB PST file into Outlook 2003.  

We ran the same Firefox and iTunes tasks from the last test again, and then did the following:

1) Open Outlook.
2) Start importing 260MB PST.
3) Start WinRAR.
4) Archive 130MB test file.

WinRAR remained the application in focus during this test.

Here, we looked at two metrics: how long it took WinRAR to compress our test file, and how many emails were imported into Outlook during the time WinRAR was archiving.  Let's have a look at the results:

Multitasking Performance - Scenario 2

Here, we see that all of the CPUs performed relatively similar to one another, but now let's talk about how many emails were imported.  The non-HT Pentium 4 imported around 500 emails, while the HT P4 EE imported around 1700 emails by the time WinRAR was done.  Neither of those are even close to the performance of the dual core chips, which each imported over 3000 emails in the same 40 seconds.  The single core Athlon 64 FX-55 also only imported around 400 emails. 

Our second test shows us that the performance of a dual core solution comes in all shapes and sizes. In this case, our foreground task took the same amount of time in almost all cases, but what was done in the background varied significantly.

    AMD's dualcore will use less power and produce less heat apparently and last I checked an FX-51 (2200) out performs the Intel 3200 in a single core configuration so it will be interesting what a dualcore AMD at 2200 or 2400 will do compared to the Pentium 4 3200 dualcore. AMD is going after the busines market where the money and the desire for dual core will be greatest. Why isn't Intel going for that market? Interesting question.

    good review! cant wait to see more info. I am particularly interested in heat dissapation as well and would be nice to see the new unreal engine that supports multithreading benchmarks but that would be be a ways off id assume.

    Is the 955X gonna support pressler? is that why it has 1066 fsb and ddr-667?

    How about a web developer test I constantly run these programs

    Dragonflycms 9.1.2
    Apache 1.3.9
    MySql 4.1
    PHP 4.0
    Photoshop 7.0
    Flash MX 2004
    Fireworks MX 2004
    Dreamweaver MX 2004
    Firefox
    Hydra IRC
    Messenger
    Yahoo Messenger

    The web server and mysql drastically effect the runing of the multimedia applications. This would be a great multitask test.

    #34 You are absolutly right there Anand, to this day I have still not had a single CPU system as responsive as my old dual O/C Celeron 550 machine. I ran it along side a P3/800 for a long time and always much prefered the Celeron box for general day to day tasks, hell my AMD 3500 feels damn fast most of the time but when I try multitask a bit too much it just takes forever to even get menus to pop down. Dual core is definately the way to go for the future, when the apps/games start to catch up with the technology everyone will wonder how they ever did without a multi core/cpu system.

    If it's any help to y'all asking about thermals, [H]ard|OCP says:

    "Our Intel 840 will have an operating voltage between 1.2V and 1.4V and have a Thermal Power Design of 130W"
  • knitecrow - Monday, April 4, 2005 - link

    thanks Anand... it is the power consumption and power dissipation profiles that I really want to see.


  • Anand Lal Shimpi - Monday, April 4, 2005 - link

    oh and power consumption is coming... :)

    These usage scenarios were described by AnandTech readers in my recent request for benchmarks, they weren't anything prescribed by any hardware manufacturers.

    Ask anyone who has used a dual processor system, things are just smoother. The reason we've never recommended dual processors systems in the past is mostly because of price. In less than 3 months you should be able to, in theory, purchase a dual core processor for as little as $240. Not since the days of the dual Celeron 300A systems has dual processing been that affordable.

    Take care,

    The best thing about dual core is that you do not need HT aware OS's anymore. It sucks when you want to run Win2000 with HT and getting slower speeds.

    Instead of trying to take screenshots, maybe you could've used one of those desktop video capture programs to try to get a better visual representation of what you were trying to explain.
