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.

    This looks very promising, my next rig is definately going to have one of these fine AMD X2 processors. Reply

    anand, thanks for the preliminary overclocking results. me and my DFI compadres are very eager to see how this chip overclocks and hope you add an overclocking page section as soon as you receive a production X2. Reply

    Would be interesting to also see if DC had any affect on SLI performance. Not sure if the driver work of splitting the duties for 2 video cards would be streamlined with a second core on the processor.

    #88 are you talking about the PD 3.0GHZ 356US or the PD 2.8GHZ 241US? The 3.2GHZ 530US is the worst price/performance DC in Intel's arsenal it cost more then twice as much as a single core and then some.

    Just like how the 4600+ and 4800+ are now costing more then twice the single core versions.

    I don't understand why people are going to assume the motherboard is expensive. Why must you have the flagship 955X motherboard?

    The lanuch pricing of the 955X is 50US, which is the same as the price of the 925X when it was launched.

    There is also the 945P chipset to consider which also supports Dual Core and is a less expensive alternative price at 38US which is only 1 dollar more then what the i915P chipset cost at launch.

    Since the chipsets base pricing match what the 925X and 915P were at launch we should logically assume that pricing of these chipsets will be similar to what i915 and i925 were at launch.

    #97, are you being serious? Read my post on #81.

    Performance drops with HT when there are memory bandwidth intensive apps due to the shared data TLB. The shared FSB also hurts Intel, and it only gets worse as you scale up with more processors.

    Since the advent of HT on P4, AMD has been at a great disadvantage in multitasking scenarios and I thought dualcore would end that. Well, I guess P4 is just better at that. Really ironic, when AMD has touted K8 as being designed from ground up for DC and Intel just slapping two cores together - LOL.

    Nontheless AMD is still doing great with X2 chips, and I too can't wait to get one, since I think we all multitask non-stop, even if we don't realize it (AV, Antispyware, SETI, FAH, Word, IE, Firefox, Opera, Acrobat, ACDsee, Photoshop, Outlook, BT, eMule, ... and the we open a game on top of that). Just yesterday my A64 3200+ S754 / 1 GB RAM gave me real trouble with gazlion windows open, while writing my graduation paper. Had to restart the bastard, grrr.

    TY for including OC results...

    maybe a whole 'nother article on this?

    i think if ppl want AMD's prices to come down, then we should all pitch in and build a new fab for them Reply
