Encoding Performance using DivX 6.1, WME9, Quicktime (H.264) & iTunes

Multimedia encoding is typically a very good CPU benchmark, with performance that scales very nearly linearly with faster CPU clock speeds. Video testing was conducted using three popular codecs and applications: Xmpeg 5.03 with DivX 6.1, Windows Media Encoder with WMV9, and QuickTime 7.1 with H.264. The complexity of the encoding process increases as we move from DivX to WMV9, and H.264 encoding is in a league of its own in terms of the amount of CPU time required. Audio encoding performance was also tested using iTunes; MP3 encoding is less time-consuming than video encoding, but it continues to stress CPU performance.

Video encoding was always one of the strong points of the NetBurst architecture, and the results in DivX and WME9 are one of the few instances where the Pentium Extreme Edition 965 can actually outperform all of AMD's dual core offerings. This is in part due to optimizations in the applications, and the advantage doesn't extend over to QuickTime H.264 encoding or MP3 encoding.

Both of the low end Core 2 Duo chips continue to impress, especially the overclocked E6400 which once again manages to surpass the stock X6800 in performance. How can a slower clocked chip outperform the X6800? Video encoding also stresses FSB bandwidth, and the FSB is running faster and providing more bandwidth with the low-end parts due to overclocking. Obviously, neither chip is actually faster than the X6800 if you test that with overclocking thrown in, but for those looking to save money the performance offered is definitely impressive.

General Performance - Encoding

DivX performance is very strong with the new Core 2 processors, and it looks like it'll take K8L to restore AMD's competitiveness here. The E6300 performs like a 4600+ while the E6400 performs like a 5000+, but once overclocked there isn't an AMD CPU that can touch either one. Given that most current 90nm X2s top out at around 2.8 - 3.0GHz on air, there's not much hope here for AMD until 65nm.

General Performance - Encoding

The situation is pretty much unchanged using Windows Media Encoder 9: the E6300 and E6400 are competitive at stock speeds but once overclocked they are now able to hang with their more expensive 4MB brethren.

General Performance - Encoding

Our Quicktime H.264 test is the most stressful out of all the video encoding tests we've got here, but the Core 2 line is quickly changing that as the majority of Core 2 parts complete the test in around 2 minutes. The E6400 is already faster than the FX-62 at stock speeds and overclocking it gives the X6800 a new neighbor at the top of the chart.

General Performance - Encoding

The AMD lineup is far more competitive under the iTunes MP3 encoding test; the E6400 is the same speed as the X2 4600+ while the E6300 is just under the performance of the X2 4200+.

    The text above the chart for the E6400 says 2.88GHz at 360 MHz FSB at 1.350V (with a multiplier of 8).
    The chart however shows 1.312V; which is what my stock E6400 runs at.
    So what's up?

    I agree about your test making the AMD cpu's look none overclocking and at the crazy price of DDR2 ram and the MOBO i just don,t see the bang here..

    My 3800+ X2 non AM2 on Cheap DDR ram can,t bring it also and make the FX62 look bad.. at 2.6Ghz it scored 7232points in 3Dmark05 cpu test on cheap DDR at a $45Mobo.. where dose that put me in your chart?? oh i am sure she could do 3.0Ghz also..

    Can anyone help me as to what RAM clockspeed I need to buy in order to overclock the E6300 on an ASUS P5B Deluxe board to - let's say - 2.592 GHz? Is DDR2-675 from Corsair sufficient? Thanks in advance

    Hey look, I was about to plunk down serious bux for an X2 setup to replace my aging P4 o'clkd 3.6xx system (that replaced an Athlon prior, that replaced a PIII prior.. blah blah). Don't you bedwetters know that this give and take is cool for everyone? No, I guess not for EVERYONE. I guess not for those butt pirates with their heads stuck so far up AMD's @ss that they can't see anything but "bias" in a review that shows FACTS. That's ok AMD girlz, take your soccer balls and go home now after trashing Anandtech. Don't forget to dry out your pretty pink wet panties.

    Man you are the thickest fanboy I have ever seen.

    Since you obviously have no interest in E6300 overclocking whatsoever, and will therefore have no fcuking clue what you're talking about, let me enlighten you:

    E6300s with Gigabyte DS3 boards are hitting 3.3 - 3.5GHz on air cooling. Check XS forums if you don't believe me. That is the equivalent of an X2 @ 4.1 - 4.4GHz. What are your beloved X2 3800+s getting? 2.8GHz? 3GHz if you're lucky?

    That means, with the right mobo, an o/ced E6300 can outperform an o/ced 3800+ by at LEAST 25%.

    You just got owned fanboy. Get a clue FFS.

    So how long will it take AMD to come up with a competitive response to the Core 2 Duo? Or better yet...do they even have a competitive response in the pipeline?

    It was nice knowing you, at least uptil Intel bought you lock, stock and barrel. After reading your latest reviews I have no doubts left in my mind, you're officially gone the THG route. I used to be a lojal reader and both linked and recommended your site to other people for unbiased information, but I will stop doing this now for obvious reasons. I hope you'll wake up and smell the coffee soon before you loose any more readers. Good-bye!

    So what are they suppose to do? Lie about Conroe's performance? You are one of the biggest AMD fanbois around, sometimes it hurts but suck it up as Intel won this round. There was not anything biased about this article or their coverage. They have been just as big AMD fans as Intel fans since the website started. Leave if you must, but do not do it because the numbers tell the truth.

    Oh boy, oh boy I want to buy one of these Conroe's right now. I'm gonna order one.

    Hmm, Newegg doesn't have them, Monarch doesn't have them, it seems nobody has them.

    Why are we worrying about comparing vaporware to something that has been out for a long time. Why don't we just compare the Conroe to an upcoming AMD 4x4 then? It's all vaporware then at least.

    Oh and let's make sure we compare lots of 64bit stuff too, after all there has been 64bit OSs around for about 15 years now.

    I ordered two from Tiger Direct and one from ZipZoomFly. No issues, received one today and the other two on Monday. :)
