Order Entry Results
Our Vendor test has received quite a bit of interest from certain processor vendors; rightfully so, as the workload is quite difficult to recreate.As you can see from the results below, there are some interesting conclusions that you can draw:
- The Dual Opteron 875 took the lead by 18% over the fastest Quad Intel. This should come as no surprise as we have seen in the past that the memory bandwidth limitation of the Intel FSB architecture does not allow the quads to really stretch their legs. On the other hand, the Integrated Memory Controller of the Opterons allow them to pull ahead.
- The additional L3 cache of the Quad Xeon 3.3GHz allows it to outperform the Quad Xeon 3.6GHz by 16%.
- The Quad Xeon 3.6GHz with the 667MHz FSB is only able to outperform the Dual Xeon 3.6GHz 800MHz FSB by 5%.
- The dual Xeons are able to outpace the dual 252's by 2%, and the single 875 by 5%. The Xeons success here can be attributed to the additional L2 cache.
- The Dual Opteron 875 demonstrated nice scalability by servicing 52% more requests in the same period as the single Opteron 875.

If they would have the dual-core in stores in June, I would buy one, but this isn't the case, so I'll buy San-Diego 4000+.I'll upgrade when quad-core will be out.

oh, you cant edit your comments...Anyway, im really excited about this development of computing, not having good multitasking ability feels so outdated, i've been crying about that for years, and fianlly its here...
Well, almost, and its probably another year before i can afford it, but still... :)

Again, the lack of technical superiority of AT's "experts" is obvious. On SQL Server, you're not supposed to prepend stored-procedure names with "sp_", as it introduces a performance penalty. This is basic knowledge. Some have remarked before on how their .NET "experts" code like, um, transplanted ColdFusion "experts". :)Visual - Sunday, April 24, 2005 - link
a minor error: on page 12 right above the graph it says "The Dual Opteron 252's lead by 19% over the closest Xeon, which was the Quad Xeon 3.6 GHz 667MHz FSB" but the slowest xeon is the 3.3 GHz one.mechBgon - Saturday, April 23, 2005 - link
Zebo... hehe, yep :Djustly - Friday, April 22, 2005 - link
An outstanding article about AMDs duel core, just what I would expect from Anandtech (to bad I had to go to techreport.com to read it).Zebo - Friday, April 22, 2005 - link
Hahaha makes Chetta's drool: Looks just like you MECH.:)MACKTEK - Friday, April 22, 2005 - link
I appreciate the article but am disappointed by the misleading title... AMD's dual core Opteron & Athlon 64 X2 - Server/Desktop Performance Preview. The 939 is not equal to 940. Also, the article clearly saysCOMPARE ATHLON 64 X2... right on the 1st page. In fact the article does not admit to "not having a real x2" until page 13. I love reading anandtech's articles and visit frequently... Perhaps a better title would have been... Preview of Athlon64 X2 using an Opteron CPU.

http://pics.bbzzdd.com/users/mechBgon/drool.jpg#82 says "and corporate PCs could work perfectly and more with a K5-K6/P2-P3."
Ahhh, this again. You obviously haven't worked with a fully-armed installation of McAfee VirusScan Enterprise 8.0i. *evil grin* Hope you enjoyed your stay in 1999... welcome to 2005.
