File Compression Performance

In order to save space on our hard drives and ensure we had another CPU crunching utility, we will be reporting our file compression results with two different versions of WinRAR. Our first file compression test utilizes WinRAR 3.51 to compress our Sum of All Fears Chapter 9 test file and our INXS Greatest Hits wma extraction tracks. All default settings in WinRAR are utilized along with our hard drive being defragmented before each test.

The Intel platform basically zips away from the AMD platform in our tests. File compression is a very CPU intensive application and also stresses the memory subsystem heavily. The added cache of Core Duo certainly helps in this particular test. The other interesting result is that our performance results scaled almost 1:1 with the increase in CPU speed, again indicative of a benchmark that makes good use of CPU cache. As an example, our Intel system has a 53% increase in CPU speed while the file compression numbers improved 52% in the Sum of All Fears benchmark and 59% in our INXS Greatest Hits compression test.

Our second series of file compression tests utilizes WinRAR 3.60b2 to compress the same files as before. All default settings are once again utilized in WinRAR along with our hard drive being defragmented before each test. This particular version of WinRAR fully supports multi-threading operations and should be of particular interest for those users with dual core or multi-processor systems.

The program update to WinRAR produces stunning results as we see drops of up to 66% in our Sum of All Fears results and 48% in the INXS Greatest Hits benchmark due to the multi-threading support. We also see the gap close up to 11% between the two platforms indicating our AMD Opteron has improved performance under this application. Basically, the multi-threading support in this version of WinRAR has negated the need for an additional 1GHz of CPU speed.

    Hi Gary, just wanted to drop in and give you a kudos on this very nice review!

    It also makes me smile to finally see Intel catching up with AMD, this can only be good news for the customer...

    And a small heads up, there are a few Intel Core Duo Engineering sample CPU's on sale at eBay, "hint hint engineering sample=multipler unlocked"

    And also a big thanks for finally posting those capacitor shots and mentioning them, keep up the good work!

    Also I think Aopen deserves recognition for designing a mainboard with so high-quality components, Rubycon=Way to go!!!

    Thank you for posting these links. :) We have a policy of utilizing the latest driver sets on a supplier's website at the time our testing starts, in this case the Intel general download page is still posting the 7.2.2.1006 driver set. However, I am using the 7.3.1 driver set on our retail board sample tonight. ;-) Reply

    Hello Gary,

    Sorta funny how that other fellow has absolutely no idea what he is talking about.

    I just wanted to touch upon something that I didnt see get much attention.


    You should have mentioned in your article about how efficient the core architecture is, and how well it scales with increased frequency. The chip turns into a total monster once you get past 3ghz, and continues to perform better and better as you increase the speed. The fastest I could get on air was around 3.1ghz. I wouldnt be afraid to crank the volts to the 1.5 max on the aopen board... with a different cooler, you should hit some nice speeds. Try swapping out for a zalman 9500, or a big typhoon.

    The shortfalls, are as you mentioned the southbridge lacking raid, and the poor bios options. Vcore should let us up to 1.65-1.7, while Vdimm should let us do atleast 2.3.

    While this may not satisfy the most serious enthusiast, this board does fill a nice niche. The price is pretty high, but core duo CPU's can be had on the cheap, which makes up for it. For someone that is worried about their electric bill, and wants performance and performance per watt, this is a great alternative.

    For others who must have the fastest. This just makes them drool. This is the low end of the core architecture. Merom and Conroe to follow... we shall be stunned.

    Consdering Meroms being tested now at 3.0Ghz are faster than 3.2Ghz Yonah's... AND YOU WILL SEE Conroe EE at 3.33 w/ a 1333fsb doing 4ghz w/ 1500mhz FSB :)


    For those that dont get it yet... AMD will need a AM2 processor running at about oh 4.8Ghz to beat a 4Ghz clocked conroe :)

    Good things to come. I take no sides, im just excited about new stuff :)

    How come a ~1 % cpu usage translates into a massiv 20 fps drop in BF2? Looks like EA have a deal with Creative :(

    A lot of world records have been beaten with this mobo already over here at XS :)
    coolaler even got SLI enabled on it ;) also running a merom in it ;)

    Your 266 FSB is very good and about normal for aircooling. Give it some cold and it will go further ;)

    [font color="#000000] (Damn white text. Nice comment engine AnandTech.... Need a new programmer?)

    Because RightMark is a theoretical test and not actually a real game or audio application. Also, look at the 3D/EAX scores - it's more than 1% CPU usage, but still less than 20% or whatever.

    It has to do with the Realtek driver load and Creatives to some extent being split between the cores during the RightMark testing. I noted in the text that although the cpu utilization is extremely low in our Rightmark results due to the load balancing that the actual game results (percentage differences) were basically the same as our single core scores. The drop in BF2 is due to the audio algorithms being generated by the CPU rather in hardware as on the X-FI card. Our audio settings in BF2 are set to hardware, medium quality, EAX enabled, the high quality setting extracts another 6FPS but we generally have not noticed an increase in audio quality. This is one penalty you pay for on-board audio in a CPU limited game although Serious Sam II is the one exception for either solution.

    We are hoping to receive a T2700 chip from Intel shortly and will "chill" it to see what results come from it. :) Yes, we had SLI working on the board also, but that is a topic that will be buried with Jimmy Hoffa at this time. ;-)

    Intriguing last 2 sentences.

    The comments section has some really good info alot of the time :).

    And kudos for bringing into the review something about the penalty for using onboard audio versus dedicated hardware.

    You're not by any chance planning on writing something about audio quality some-time? Not that im an audiophile or the like, just curious.

    We will expand our audio section in the next update to our motherboard review section. We are looking at several variations of the review process as we enter a very busy time of the year with AM2, Conroe, and others all launching over the next 90 days. :)
