The Test

We've already covered the architecture behind Intel's Core 2 processors extensively in the past, leaving the only unanswered questions centered around final performance. Today we're here to answer these questions, and we'll focus exclusively on performance. If you want to read more about Intel's Core architecture, please look back at the following articles:

Intel Core versus AMD K8 architecture

Spring IDF 2006: Introducing Intels new Core Processors

Because AMD is killing off its 1MB L2 Athlon 64 X2 parts, we've only included 512KB X2s in this review. The Athlon 64 FX-62 features a 1MB L2 per core and is obviously still included.

    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...
  • xFlankerx - Friday, July 14, 2006 - link

    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).
  • Calin - Friday, July 14, 2006 - link

    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.

    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).
  • duploxxx - Friday, July 14, 2006 - link

    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.

  • duploxxx - Friday, July 14, 2006 - link

    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

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