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 being that we wanted a more realistic test (from a file size/count perspective) as well as the ability to discern better 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:

File Compression + Multitasking Environment

The Pentium D 840 was the fastest CPU here, even faster than the HT enabled Extreme Edition 840, which actually came in last. What's even more interesting is that the FX-55, a single core CPU, did better than two of the dual core chips. 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:

Outlook PST Import + Multitasking Environment


Update: AnandTech reader manno pointed out that the metric we should be looking at here is emails imported per second while the archive task was running. Looking at these numbers, Intel actually comes out ahead with the Pentium D 840, with AMD in second place. All of the dual core chips outperform the single core Athlon 64 FX-55 by a huge margin, and once again, we see that Hyper Threading isn't always beneficial as the Extreme Edition actually runs slower than the regular Pentium D here.

    Sounds like computing could change a lot in the next 6 months.

    I can't wait to get my hands on a dual core chip - that type of multitasking gaming performance is what I've been waiting for... 92% of unfettered performance during Doom3? That's unbelievable.

    Another thing to consider is that the 939, and 940 Dual Cores work with old mobos. so that saves upgraders ~$100 for the mobo (I have no clue what PD mobo's are going to cost) plus the cost of DDR2 ~$100 for 512MB, not true if you're going with the PD. So if you own a 939 a 2.8 PD will realy cost you ~$441, 3.0 -$516, 3.2 ~$730.
    Throw that out the window if you're starting from scratch however.

    Great review very detailed, I have one caveat, and I should preface it with the fact that I own 4 systems, and all of them have Athlon 64's or XP's.

    That being said your "Multitasking Scenario 2: File Compression" Seems to be misleading, and identifies the A64 as the processor of choice in the 2nd portion of the analysis.

    Maybe I'm wrong but from what I understand with how the test was performed you archived the file, got the amount of time it took to archive the file "x" for instance, and then figured out how many emails got imported in time "x" now because some processors took longer to create the archive than others they had more time to import emails. so in order to make this data more reflective of the performance of each processor you need to divide the number of emails imported by "x", and get e/s. The modified graph should be

    PD 3.2 =19124/5.08 or 3764.57 e/s
    A64 X2 =21687/6.25 or 3469.92 e/s
    PEE 3.2 =16875/6.65 or 2537.59 e/s
    AFX 55 = 3800/5.88 or 646.26 e/s

    These corrected numbers show that at least in this test the PD 3.2 is the winner by ~8%

    At that prices, most of the users really won't need their current mainboards for new dual core processors. I would prefer to have lower priced single core than that prices on dual core.

    We are talking about by this fall, folks. And a 90nm Dual core still uses LESS die than 2 2800+ put together because it is on a manufacturing smaller process, especially if they stick to a 512k cache which is obviously the sweet spot. By this fall I expect that we will see sub $200 dual cores from Intel to squeeze AMD on the desktop market. What is a real shame is that AMD doesn't have suffcient fabs to handle potential demand.

    For those of you who got all hot in your pants and said I can't buy a sub $200 dual core Intel right now, it is just as true that I can't buy one it all! ;P Chill!

    Impressive.

    Am I mistaken in thinking that AMD was throwing out their desktop dualcore line (A64 X2) in 2006? What prompted their earlier release of them? Was it the demand for desktop dualcore, pressure from Intel stealing desktop dualcore market, or excellent manufacturing at the AMD plants?

    blckgrffn, "so if they can't bring anything out under $200 I will probably have to go with Intel. Boo for that ;) "

    INTEL doesn´t have one under $200 either.

    #14... all socket 939 motherboards will support the X2 with a BIOS upgdate.

    #9 They'd have to release a 1.6 @ $240 to accurately compete with Intels slowness in Pentium D's starting at $241. Sorry not gonna happen. AMD not for budget shoppers anymore but those interested in performance. Want the best? Pay the price. Or substandard CPU at a discount?

    I can see a 1.8 for about $250 though however no way you're going to get into DC for less than $200.
