The Test

Our test configuration is identical to what we used in our Athlon 64 X2 3800+ review, however we can’t disclose the motherboard used for the Yonah platform.  We can say that it used the Intel 945G chipset and was outfitted with 2 x 512MB DDR2-533 DIMMs; the rest of the configuration remained the same as the AMD and Intel systems.   

Once again, keep in mind that the platform and processor are pre-release samples, and performance could change by the time the parts head to retail. This is nothing more than a preview, so treat it as such.

Business Winstone 2004

Business Winstone 2004 tests the following applications in various usage scenarios:

. Microsoft Access 2002
. Microsoft Excel 2002
. Microsoft FrontPage 2002
. Microsoft Outlook 2002
. Microsoft PowerPoint 2002
. Microsoft Project 2002
. Microsoft Word 2002
. Norton AntiVirus Professional Edition 2003
. WinZip 8.1

Business Winstone 2004

Just as we saw in the Dothan vs. Yonah tests, Yonah loses some of its competitive edge in the Business Winstone benchmark. Although in this case, it's not very far off the Athlon 64 X2 3800+.

Office Productivity SYSMark 2004

SYSMark's Office Productivity suite consists of three tests, the first of which is the Communication test. The Communication test consists of the following:

"The user receives an email in Outlook 2002 that contains a collection of documents in a zip file. The user reviews his email and updates his calendar while VirusScan 7.0 scans the system. The corporate web site is viewed in Internet Explorer 6.0. Finally, Internet Explorer is used to look at samples of the web pages and documents created during the scenario."

Communication SYSMark 2004

Yonah manages to be quite competitive in the SYSMark tests, slightly outpacing the Athlon 64 X2 4200+ here.

The next test is Document Creation performance, which shows very little difference in drive performance between the contenders:

"The user edits the document using Word 2002. He transcribes an audio file into a document using Dragon NaturallySpeaking 6. Once the document has all the necessary pieces in place, the user changes it into a portable format for easy and secure distribution using Acrobat 5.0.5. The user creates a marketing presentation in PowerPoint 2002 and adds elements to a slide show template."

Document Creation SYSMark 2004

Here we see that at 2.0GHz, Intel's Yonah is right in the middle of AMD's Athlon 64 X2 4200+ and the X2 3800+. Given that the CPU has no on-die memory controller, yet performs comparably to an identically clocked Athlon 64 X2, it's not a bad position to be in for Yonah.

The final test in our Office Productivity suite is Data Analysis, which BAPCo describes as:

"The user opens a database using Access 2002 and runs some queries. A collection of documents are archived using WinZip 8.1. The queries' results are imported into a spreadsheet using Excel 2002 and are used to generate graphical charts."

Data Analysis SYSMark 2004

The Data Analysis test is dominated by the Pentium D, but even the Athlon 64 X2 3800+ holds a slight advantage over the 2.0GHz Yonah.

    Also, isn't there a way to disable the second core in BIOS?

    I think it's definitely possible to make your dual-core chip into a single-core for testing.

    No, since it is a CPU with double execution units, rather than 2 CPUs linked together. Reply

    I've not seen that stated anywhere. What I've seen is that there are two cores, two independent L1 caches, and a shared L2 cache. Reply

    The reason it was compared against the X2 is simply because that is where the next gen Turion "may" land in performance. Power consumption in this test is nice, but not really relevant to the new Turion, nor is it relevant to the mobile arena where AMD with integrated controller does well against P-M plus external controller consumption (well though Intel is better so far).

    I had a feeling things were going to turn out this way. That cache on the P-M is really what makes it such a nicely performing chip. Weakening that was really the telling test in all this. It's nice that you put that test first. The dual core Turion is going to be very close in release timing to Yonah, and quite a few samples of the chip are already out there, but I'd bet AMD is keeping its cards close, as it has less of a need to prove a point.

    However, from a mobile perspective AMD's use of Via and ATI chipsets really will be the telling factor, and will impact the "you get it all" bundle of a notebook. Where, after over a year, is Nvidia and a pci-e mobile chipset for AMD? Turion is almost out the door and they haven't even spoken up yet. That's probably because they won't be there when Turion releases. If Nvidia had no chipset on the desktop, the competition would be starkly different right now, and a good many folks know this to be true. So I'm expecting the dual core Turion to do incredibly well. 64 bit isn't an end all be all, but it will be a wonderful perk when Vista comes, and Vista will be here sooner than previously expected. Power consumption "may" favor Yonah, however Intel is doing what they always do, when a chip performs so-so, they push up the clockspeed. When they find out what Turion has on the table, they'll put out the EE version of Yonah to try to match it. THAT I bet, won't be so power friendly.

    Intel is improving on Yonah with Conroe. But remember that the low latency L2 is what gave the Dothan its ability to stand in the A64 arena. That got lowered and we see the results. Now imagine what will happen when they "gently" increase the pipeline of Conroe vs P-M/Yonah. It'll drop a bit again. Against that you'll have architecture improvements and higher clockspeed (Conroe is expected to clock higher). That might end up making Conroe only "slightly" better than Yonah. That is why the marketing of th two can overlap, probably.

    So IF (and it's not promising) Nvidia gets the NF4 into a mobile format and gets builders to use it on the new Turion dual cores, we might see some interesting things from the AMD side. If not, they stay as now, a niche market only. ATI chipsets aren't going to change that, much as they have not done much to the desktop side of things.

    IF Yonah clocks at 2.6ghz you may see some competitive desktop systems to A64 X2's. It will rule the mobile roost unless the above happens for AMD. Conroe had better make some dramatic improvements to even Yonah's ability, though I'm doubtful, or putting both Yonah and Conroe on the desktop will simply hand even more of the market to AMD. On the mobile front, again unless the above happens for AMD/Nvidia on a mobile chipset, you will watch Yonah/Conroe rule the mobile roost.

    Intel just now managed to close the gap between them and AMD as far as dual core is concerned. I dont care if one is a mobile part and the other is not, mobile computing is of no interest to me and even less dual core mobiles. But it gives a good idea of what to expect.

    The numbers are there. Yonah isnt groundbreaking besides the fact that it is a dual core - and the desktop versions probably wont be either. Wow, thats late...

    TG Daily: What is your reason for not including support for 64-bit technology in Yonah? Why is it going to be supported only in Meron?

    Perlmutter: Like everything in technology or life, it is all a matter of timing. Integrating unneeded features into a processor means a waste of power consumption. Our assumption was, and still is, that 64-bit extensions are not the most important thing required from a processor, not even in the beginning of 2006. We believe this will change with Windows Vista, when applications start migrating to 64-bit, and we want to be ready then, and not a minute earlier.

    64-bit extensions = more transistors, which means higher power consumption. Reply

    If this is cheaper than the X2 3800, and overclocks really well on the desktop (say, 2.7-3ghz or so), then I could see myself being tempted by it. As long as the 'secret' motherboard isn't as ridiculously overpriced as current dothan desktops. Reply
  • Griswold - Wednesday, November 30, 2005 - link

    WHat makes you think that thing will go to 2.7-3ghz? *laff* Reply
  • Donegrim - Wednesday, November 30, 2005 - link

    Well the x2 3800 that consumes much more power (therefore is hotter) consistently goes to at least 2.5ghz, so I don't think it's unrealistic for a lower power chip to go further. Plus the FSB is nice and low, which makes for a good start with the overclocking. Reply
