Conclusions

Although the Athlon 64 3500+ and the Xeon 3.6GHz EM64T processors were not necessarily designed to compete against each other, we found that comparing the two CPUs was more appropriate than anticipated, particularly in the light of Intel's newest move to bring EM64T to the Pentium 4 line. Once we obtain a sample of the Pentium 4 3.6F, we expect our benchmarks to produce very similar results to the 3.6 Xeon tested for this review.

Without a doubt, the 3.6GHz Xeon trounces over the Athlon 64 3500+ in math-intensive synthetic benchmarks. Again, not that it is really a comparison between the two chips yet anyway, but perhaps something of a marker of things to come. However, real world benchmarks, with the exception of John the Ripper is where AMD came ahead instead. Even though John uses several different optimizations to generate hashes, in every case, the Athlon chip found itself at least 40% behind. Much of this is likely attributed to the additional math tweaking in the Prescott family core, and the lack of optimizations at compile time.

That's not to say that the Xeon CPU necessarily deserves excessive praise just yet. At time of publication, our Xeon processor retails for $850 and the Athlon 3500+ retails for about $500 less. The 3.6F processor the Xeon represents does not even exist in retail channels yet. Also, keep in mind that the AMD processor is clocked 1400MHz slower than the 3.6GHz Xeon. With only a few exceptions, synthetically the 3.6GHz Xeon outperformed our Athlon 64 3500+, whether or not the cost and thermal issues between these two processors are justifiable.

We will benchmark some SMP 3.6GHz Xeons against a pair of Opterons in the near future, so check back regularly for new benchmarks!

Update: We have addressed the issue with the -02 compile options in TSCP, the miscopy from previous benchmarks of the MySQL benchmark, and various other issues here and there in the testing of this processor. Expect a follow up article as soon as possible with an Opteron.

    Come on people this is Anandtech, have they ever appeared to be anything, but honest, and unbiased in their reviews? These are the number they got using these benchmarks. They did the work, and gave you the numbers. This site isn't here to advertise for AMD, or Intel. They give you the information, and you use it as a tool for you own purposes from there. I mean come on take of your uniforms, and accept what you see in front of you. This should be looked at as a favor. I don't see any other sites posting benches of Intel's EM64T chips, do you? You came to this site by choice, they don't charge you dime one for the service they provide, and you get pissed at them for not bending the truth so you can to advance your own personal agenda.

    Say thank you, and be on your way.

    These guys work hard, and they do a fantastic job supplying the enthusiast community with some of the best benchmark numbers around. They just posted numbers showing that EM64T is a huge step forward in terms of P4 performance. So what? If you want to buy an A64 or P4 Prescott and get worse performance in those benches then go out and buy one. I was just about tho buy a some PC's for the office here, and they were all going to have A64's in them. Thanks to Kristopher I've decided to sit on the fence a little longer.

    Again Thanks for the early release, it really and truly helped. I hope these fanboy's don't affect you decision to post early numbers in the future.

    Is this what you call these days a *benchmark*? Just wondering... o.O

    hello. someone effed up :(

    Not a bad article, though it might have been better if an Opteron 150 was benched which is priced @ 637US or the Athlon FX 53 @ 827US those would be closer in comparison to the Pentium 4 3.6 Nocona EM64T

    Though eventually a fairer comparison would be the Pentium 4 3.6F vs the Athlon 64 3500+ or Athlon 64 3700+. You could also throw in the Pentium 4 3.4F and Athlon 64 3400+.

    at least compare the same thing, if you don't have the same class CPU for testing THEN DON'T POST THE ARTICLE.

    Given the numerous errors in this article, I believe it is prudent that it be removed from Anandtech.

    This ludicrous article has damaged my opinion of Anandtech.

    Wow... and a big fat Intel ad at the bottom of the article. Never thought I'd see the day.

    Good review, thanks for the early benchmark release. I'm not going to lie to you I like AMD, and I own a bunch of Athlon 64s. But before I think I'll hold off on buying any new hardware until I get to see how well these new P4's do. Any chance we can get some Doom 3 numbers up? Again thanks for giving us the heads up. Looks like things could start heating up in the Chip market soon!

    wow intel fanboy alert.
    I also joined the forum just to post here.

    Numerous forums are all comenting on this article. Anand's is even compared by some to THG. So I think an update is appropriate here. A delete to.

    T8000, maybe you should read some of those comments, you would discover that , compared to an opteron, results would be very different. Results that aren't even correct btw. And that the benchmark choice is awfull.

    The gcc options used don't generate 64-bit binaries.
