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 the source code to Firefox while importing a 260MB PST file into Outlook 2003. You'll note that this is a slightly modified version of the test that we originally created; we modified the test by archiving the Firefox source instead of a single smaller file. The reason for this is that we wanted a more realistic test (from a file size/count perspective) as well as the ability to better discern between contenders.

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 Firefox source.

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 that WinRAR was archiving. Let's have a look at the results:

Multitasking Performance - Scenario 2

Remember that Windows' scheduler will give, by default, priority to the foreground task, which is why we see such a strong showing from the FX-55 here. But let's take a look at the other main task that ran in the background, the Outlook PST import:

Multitasking Performance - Scenario 2

Here, we see that while the FX-55 completed the archive task quicker than the dual core AMD CPUs, it basically got nothing done on the import emails task. Here, the advantage of dual core is clear, and once again, we see that AMD and Intel are very close in performance, but with Intel taking the crown. Interestingly enough, Hyper Threading is a major hindrance to Intel here as the Extreme Edition is significantly slower than the HT-disabled Pentium D 840.

    Would have been nice to have a 2.8GHz Pentium D so you could get a sense of how the Intel chips scaled with an increase in the clock speed. Reply

    I just looked into this article because my destkop in 2019 on windows 10 has it.

    man its insane how dual cores were powerful at this time.

    so crazy that this was 15 years ago, and yall never had a clue that there would ever be 64 core processors today... Reply

    Hah I was reading this review 15 years ago and with their prices back then I was only dreaming about the 1024kb dual core ones :) Well I took it 3 years later second hand Athlon 64X2 4800+ :D Still working on Asus A8N-E with a ATI HD4850 now used by my grandfather just to read the news :) Reply
