As we look toward the introductions on September 23rd, some things are starting to become clearer about Athlon64. Announcements from AMD and word-of-mouth all point to the performance of Athlon64 and Opteron being very close if not identical. We also are hearing rumors from the Inquirer and elsewhere that the 754-pin Athlon64 will likely be introduced initially at 2.0GHz, with a revised (and more realistic) Performance Rating that will place it somewhere around 3200+, which is the current highest PR of the top Barton. However, no one has really done much in answering how the Athlon64 will perform compared to current Athlon and Pentium 4 CPUs. While the delay of Microsoft’s 64-bit Windows XP still will not allow us to test 64-bit Athlon64 performance, we do have the tools at hand to give a good idea of what to expect from 32-bit Athlon64 performance when it is introduced in the next few weeks.

When Anand Shimpi first tested Opteron in April, there were only server-based boards available for testing. The single-CPU nVidia nForce3, which has real AGP 8X and Enthusiast-level overclocking options, would not be released for a couple of months. With nForce3 for Opteron now available in the market, and the expectation of a 2.0GHz Athlon64 introduction, we went back to our nVidia nForce3 reference board with an Opteron capable of running 200FSB to see where Athlon64 might land.

With the AGP/PCI lock and FSB overclocking of the nForce3, we were able to reach a stable 2.0Ghz (222x9) at default voltage with our 1.8 Opteron, even though we were running 2GB (512MBx4) of Dual-Channel ECC memory. With full support of AGP 8X, we were also able to use our standard ATI Radeon 9800 PRO for benchmarking.

With the nForce 3 running Opteron at 2.0Ghz with a Radeon 9800 PRO, we had the platform to give our readers a decent preview of Athlon64 performance. So how will Athlon64 likely compare to the best Pentium 4 CPU’s and current Barton processors?

    I found it difficult to compare products because of the way the descriptions of processors and components were laid out.

    Well for any Intel posters you can avert your eyes. I've recently been doing some shopping to piece together a new system for myself. I'd decided on AMD since their systems have always been good to me and cuz ..screw the big boys.
    Anyways I've been out of the hardware game for a while and the 64bit cpu is really interesting for me. I do a lot of 3d animation and video editing. SO my question is this 1)is there a trustworthy, compatible Mobo out there now that will work with amd64 that I could build now and upgrade up to later? 2)Is there another solution from the current 32bit amd processors that could give me all my needs (gaming, animation, editing, etc..)? or should I just wait for 64 to come out (which I really REALLY need to build a pc fast)??
    I'm open to any and all suggestions :)

    Speaking of AMD vs Intel & the Sysmark 2002 cheating allegation, just wait until XP-2003 for AMD comes out and you install Sysmark 2002. Anyone with half a brain will understand what Intel & Bapco did to stack the deck when the system reboots after install. Very revealing.

    Remember this.

    Hmmm, talking about stocks. Actually in the last 3 months, AMD also doubled its price. So, if you own either Intel or AMD stock, you will have gain a lot of money. The stock increase occurs because investor expect that the chip sector is improving this year, i.e. there is an increase in the demand of cpus. Reply

    I don't know if anyone is considering this but don't you think the prices for a processor are becoming a tad bit HIGH!? As it stands in order for me to get a piece of this new technology(Athlon 64 and its motherboards) I would have to cough up $1000+! $1000 for a cpu and motherboard!!! For companies that want its customers to flock to thier stuff when they release them that is TRULY not encouraging anyone to go out there and buy at all. As it stands I don't think a lot of people will be able to buy this thing right off the back no matter how bad they want it. The Opteron 940 is higher than my HOUSE NOTE right now for my 2-story home. The AthlonFX isn't any better. Right now Directron.com has the Athlon64 up for pre-order at the price $489. Ladies and gentleman that is a whole f***ing check for most people. I really do think that the Athlon64 and the Opteron are an advancement and a powerful one but could they please stop raising these prices? Reply

    Please stop repeating the same questions...

    The only thing I wanted to point out is that the drivers that are recompiled for the Athlon 64 are going to make a difference more than anything else discussed in this comment section.

    As for this Pentium 4 arguement, the P4 3.2 GHz 800MHz is $613. That is about $200 more expensive than the Opteron 242 and $150 more thank an Opteron 144. The MBs will become cheaper due to the lack of a Northbridge and ease of design. $130-140 is the price I expect the Nforce 3 boards to sell.

    Whatever you want is what CPU you should use. Just know that if you buy an Opteron or Athlon 64, that every driver update is going to get you more speed. Every update patch to games will get you more speed. And you have the ability to go to Windows XP 64 when it is finished and run even faster. Over time, you may have a 20% or more improvement in speed. If it doesn't, then you have a really fast CPU at 1.8 GHz running less than 39c while benchmarking.

    It will be a nice laptop.

    The testing methology is flawed here.

    You have an Opteron that is OVERCLOCKED to 222MHz HT bus/RAM, versus a stock standard 3GHz P4 (why no 3.2GHz?)

    It's like comparing a 2.8C @ 3.2GHz and comparing it to a 1.8GHz Opteron. I'm sure that would create an uproar of 'Intel BIAS!' type of comments. ;-)

    Don't get me wrong, Opteron/A64 is an impressive processor, but the review would've been much more credible had Anandtech reviewed a stock 2GHz Opteron vs a 3.2GHz P4, instead of an overclocked Opteron 1.8GHz @ 2GHz with faster HT bus and RAM, compared to a 3GHz P4, which isn't even the fastest available.

    I'm a noob and I have a question. I'm not understanding how us gamers will be able to play our games (like bf1942) when these processors come out if there isn't a 64 bit OS out for us to run. Can anyone clear this up for me? Reply

    Considering this was testing its performance on a 32bit OS, I cannot wait to see how well it fairs in a true 64bit enviroment!

    I say....each to their own preference. Be glad you have the option to choose Intel or AMD and that their competion produces a less noticable strain on our pockets!

    #18, some Xeon's (not XeNon) have 1 meg L3, as well as 512 K L2 like any nortwhood. The L3 is inclusive however, which basically means that data stored in L2 is also duplicated in L3 to allow faster chaches. This results in a "net" cache size of 1 Mb, not 1.5. Reply
