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.

General Performance - Video Encoding


In something of a change, both the Core 2 Extreme and that E6300 manage roughly a 25% margin of victory over their AMD counterparts in the DivX test. The E6300 very nearly matches the X2 5000+ here. The X6800 maintains the 25% lead in WMV9, while the E6300 lead over the X2 3800+ drops to 8.5%, roughly equaling the 4200+. Finally, in H.264 encoding, the Core 2 Extreme claims one of its largest victories coming in 36% faster than the Athlon FX-62; the E6300 also manages a large 21% performance lead over the X2 3800+ and falls between the 4600+ and 5000+ in performance.

General Performance - Audio Encoding


Moving over to audio encoding performance, we used Apple's iTunes 6 application to encode a single 307 MB Wav file into a 192kbps MP3. Audio encoding is still very CPU intensive, but of course the faster encoding times make the differences less noticeable in practical use. At the top and bottom price points, Intel leads again: 5% at the low-end, and 15% at the extreme performance segment. Unless you frequently encode really large amounts of audio files, however, it's unlikely you're going to notice Intel's 2-4 second lead.

    A very good part of what Intel makes (processor wise) goes to mainstream and lower-than-mainstream performance (Celeron-like chips). There might be, in the end (of the year), enough production of Core2 to fill the enthusiast/retail market.
    Indeed, the Netburst are obsolete over night...

    Not just Netburst, even the Athlon 64s are obsolete now.

    With the Pentium 4 vs. Athlon 64 debate, atleast there were moments when going with the Pentium 4 could be justified. However, because of the huge difference in performance and prices of the Core 2 Duo and Athlon 64 processors, I think it would be foolish to go for a new Athlon 64 system right now (unless ofcourse you're on a tight budget).

    Yes, Pentium4 was better in so-called media benchmarks, and there were some uber-optimized application that were flying on Pentium4.
    Right now, there are (as stated in article) three competitors: Core2Duo at high price, performance and low power, Athlon64 X2 at lower price, performance and a bit higher power, and PentiumD at dumping prices, even lower performance and quite a bit higher power. It all depends on how much money you would invest.
    I am thinking at a single core Core2, and integrated video mainboard with ATI or NVidia chipset - or a Sempron AM2 3000+. I wonder how cheap a Core2 Solo would be

    Agreed, an excellent review, I loved Anand's anologies about the dinner table. I get the feeling he may have been thinking Arby's (tm) when he wrote this review. :)

    My goodness does Intel's new lineup impress. I've been using AMD ever since the K6/2 days and was planning on getting an X2 soon, but this review has made me decide to wait it out just a little bit longer.

    Great article guys, keep up the good work.

    I'd say that the A64 X2s are still quite competitive, depending on your budget and availability of the C2Ds.
    That said, Intel has done a magnificent job with these chips!
    It looks like Conroe will own the high end market until AMD can release K8L...but judging by the review, AMD will own the low end. I can't see anyone buying a PD once AMD drops the prices, nor can I see anyone buying an AMD if they can afford a medium or higher priced system.

    With the 1.83GHz conroe at $183 and on par with a X2 4600, I don't see the low end going for AMD either.Ultra low end will be a toss up however. Reply

    If you look at the situation in total, it will probably make more sense...
    1. The X2 has far more inexpensive but fully functional motherboards to choose from.
    2. Supply will be far more constrained on the Conroe than on the X2

    Combos are king in the low end...for example, if you combine an Asus M2NPV-VM with an AM2 X2 3800 (after the price drop), you get a good dual core system with Raid 5, HDTV, nVidia 6150 graphics, Firewire, dual screen (VGA and DVI), and just about every whistle and bell you could want for (est) ~$250. You'd be hard pressed to find just a Conroe-ready motherboard with that kind of functionality for that kind of money (let alone a combo).

    correct the real performance king will be for now the conroe starting from 6600 and above. maybe 6400 this will be clear later. but for the budget platform it will be better to buy an x2 3800 or 4200 seeing the price combo it will have. mobo + proc is way cheaper then any intel combo (100$ and more) thats a lot for a budget system.

    oh and one big item which is left out of sighht... the performance gain is less on a conroe then on a k8.. its a difference of 15% in identical apps... that's an interesting point for the future... just my opinion Reply

    Yes it was a very, very well done review and I will definitely be purchasing one of these bad boys. Reply
