Final Words

Now armed with final silicon, our stance on AMD's Athlon 64 X2 doesn't change at all - AMD clearly has the faster overall dual core desktop solution, but at a price that will be out of reach for most users. Eventually, AMD's pricing will fall to a level that is far more reasonable, but unfortunately, that time won't be until 2006 at the earliest. We've already looked at the slow dual core vs. fast single core debate, but be prepared to be put in that very position later this year as both AMD and Intel bring their dual core CPUs to market at very different price points.

What we did find interesting was that while AMD generally maintains a large performance advantage in single threaded applications, our multitasking scenarios were a mixed bag of results between AMD and Intel. The multitasking gaming tests were obviously very strongly in favor of AMD, but the general usage tests were more mixed between AMD and Intel. In many cases, Intel's Pentium D actually pulled ahead in terms of performance.

Also, in our multitasking tests, there were a couple of cases where we saw no major performance difference between the Athlon 64 X2 4800+ and 4200+. It was mostly in the single application (both single and multi-threaded) that we saw the most noticeable performance difference between the two CPUs.

The other thing we continue to see is that dual core with Hyper Threading in these multitasking environments is very much the double-edged sword. There are some situations where having both Hyper Threading and dual core gives Intel a huge performance boost, but there are others where the exact opposite is true. As it currently stands, we're not sure how much of a future Hyper Threading will have in future Intel architectures - but it's definitely not a sure win.
In terms of availability, AMD is encouraging all reviewers to mention that the Athlon 64 X2 will be available starting in June. However, that availability in June will only be through select system builders, probably very similar to Intel's current dual core "availability". Widespread availability of the Athlon 64 X2 won't be until Q3 or Q4 of this year, and we aren't sure when we'll see widespread Pentium D/Extreme Edition availability either. AMD did deliver on their promise and is making sure that dual core Opterons are out and available for the enterprise markets, however.

With the last of our product-specific dual core previews out the door, now we all play the waiting game. But with both AMD and Intel pushing dual core heavily, we can only hope that the wait won't be too long - especially from the standpoint of improving software support for dual core systems. Today, we're able to show some very tangible performance gains for dual core CPUs in multitasking usage environments, but in the future, single application performance should get a very tangible performance boost as well.

    Anand, have you tried overclocking these X2 chips?
  • AnandThenMan - Monday, May 9, 2005 - link

    Very poor (pre)review IMO. Not nearly enough multi-tasking tests, and NO overclocking tests for some strange reason. And what about power consumption tests? Observations on heat output?

    And I agree with #18, the Q3 or Q4 statement with no explanation is odd and getting annoying.

    Hothardware and Thetechreport have much better preview articles.

    AMD is playing a bit of a word game with regards to availability. When they say available in June, they mean that through select system system builders the Athlon 64 X2 will be available in June. Across the board availability (as in you'll actually be able to buy an Athlon 64 X2 CPU alone) will be Q3/Q4 - that is directly from AMD to my inbox. It's just that availability in June sounds a lot better, much like Intel saying that availability in May sounds good - both companies appear to be playing the same word game ;)

    Take care,

    NIce review Anand, I've more or less chosen the 4400+ X2 as my next processor from my XP 2100+. She's getting venerable now, pushing 3 years old now.

    I just creamed my pants. Who the F*ck wants an 820 Pentium D with you can have a freaking "X2" F*ck yeah! thats Xtreme muther F*cker!

    Its like that "America F*ck Yeah!" song from America World Police.......

    "Wal-Mart, F*ck yeah! Taco Bell, F*ck yeah! X2, F*ck yeah! Pentium D..............(Distant) fuck yeah?"

    wow this is the most F*cks I've seen in a single Anand post, or thread for that matter.

    F*ck it. I'm all for setting records :)

    When the time comes, an X2 shall be a nice upgrade from my current s754 3200+ :)
  • dougSF30 - Monday, May 9, 2005 - link

    What's with the opening bias?

    (1) AMD, unlike Intel and the 840EE, does not claim to have launched the X2. Providing a performance preview != paper launch.

    (2) AMD states in writing that the X2 will be available in June. Not "Q3 or Q4". This is the second time Anandtech has made these "late this year" comments which contradict AMD's official stated position, with no explanation.

    Thanks Anand:)

    DrMrLordX, if you really think it's poorly priced consider this. the lowest end San Deigo, aka the "value" line in that series, a 2.2 is $350. Adding another core is only 50% more money inside 4400.

    Don't even start looking at dual opteron 248's which cost $1000 just for processors, not to mention expensive ECC and mobos pluys it's slower.

    I see real value in the 4400 and I'm a huge proponet of $70 wonderchips like XP mobiles.

    This is a workstation chip with a cheaper than workstation price.

    Great article BTW. AT is my fav review site.
