Forum Test results
Unlike the Dell DVD Store test, Woodcrest demonstrates a commanding lead at all load points. Woodcrest is able to lead the Opteron 285 by 10%-35% and Dempsey 3.73 by 18%-58%. The Forums test was harder to throttle at the lowest load point, thus the first load point results do not fit entirely into the expected linear model. In future reviews we may try and address this.
This graph is similar to the Dell Power results. Woodcrest is again the lowest consumer of power. Woodcrest leads the Opteron 285 by 13%-14%, and Dempsey 3.73 by 24%-34%.
Lower power and higher performance of course makes Woodcrest the clear leader at all load points in terms of Performance/Watt. It leads the Opteron 285 by 26%-58% and Dempsey 3.73 by 73%-108%. Again note that the Opteron 280 outperforms the Opteron 285 in terms of Performance/Watt.
Conclusion
It took a few years, which is normal for any architecture redesign, but we feel Intel has finally created a product that is not just competitive to the AMD Opteron. Woodcrest outperforms all of the competition in 2-way configurations, and it does so with lower power consumption. This combination leads to better Performance/Watt in all tested situations. Woodcrest not only outperforms it's predecessor by over 100% in Performance/Watt, but it outperforms Opteron by as much as 60% in Performance/Watt. In terms of straight performance the Woodcrest led the way by anywhere from 18 to 35% at higher system loads. We feel that Intel has the vision to continue this trend, as they have a clear roadmap for next year and beyond. Expect to see even further gains in 2007. How those parts will compete with future AMD products is unknown, but we have competition and that is always good for the consumer.

What's the fastest Opteron dual core CPU you can buy?What's the fastest Woodcrest CPU that will be released?
AMD don't make anything faster than 2.6GHz, so it doesn't really matter what speed Intel have to be at to beat it, they beat it with their top end part. And the Opteron is nearing its end (at 90nm), Woodcrest is new, so it will go faster probably, same as 65nm Opterons will go faster.
Woodcrest is not behind Opteron, it is better per watt, and the high end Woodcrest beats the high end Opteron. Enough said. Whether Intel is clock for clock better or not still doesn't matter. They are better, and if they are not better clock for clock, it doesn't seem to matter because, again, they have higher clocks.

"What's the fastest Woodcrest CPU that will be released? "Umm.... None?
Does that mean AMD beats Intel by an infinite margin then?
True, if Intel has a 3ghz part out, and AMD only has 2.6, then it makes sense to compare these two.
But for now, let's just keep in mind that Intel doesn't have a 3ghz part out. They don't have a 2.6GHz part either. We are still comparing an unreleased product to one that has been out for a while.

You should note the way the two processors are compared here. Both are dual-CPU systems. Intel's FSB based system architecture means lower system bandwidth than AMD's DirectConnect architecture. The Opteron's have an on-die memory controller and a point-to-point interconnect. I am sure if you put Woodcrest on a Paxville system, you would see significantly worse performance. The 3.0Ghz Woodcrest is probably capable of a bit more performance, but the lower bandwidth FSB does not help it reach its full potential. Also coupled with the fact that FB-DIMMS have more latency than standard DDR2 means the Woodcrest isn't at a serious advantage compared to the Opteron system.Bottom-line system performance for the Woodcrest processor is still 5-20% better than Opteron. But thats way better than being 30% lower during Paxville days.
Now Conroe does not have all these complications that Woodcrest has, thats why you may see better performance advantage, also since it is a single-CPU solution, the system architecture is much simpler.

how many people running servers are going to overclock their system? :Dfitten - Thursday, July 13, 2006 - link
Zero. I'd fire any IT person on the spot if I found out they had overclocked a production server.FesterOZ - Thursday, July 13, 2006 - link
I find this article somewhat surprising in tone. My company is a Fortune 500 and a big Dell shop so we have had access to Woodcrest workstations and servers for testing for a while. We have also tested these vs HP 9300 Athlon based Workstations and vs Sun x4100 servers and HP DL385s. Based on our tests which involve business applications, trading applications, etc., the performance of Woodcrest vs the Athlons is slightly better (about 5-10%). Nothing to really rave about, especially when its the latest Intel designs on 65nm. This actually disappointed our in-house Dell groupies, especially since they were comparing the top of the line new CPU design from Intel vs AMD's older platform. As a result we are moving away from Dell simply because they do not offer choice of CPU's at the moment and into HP's world, with our first purchase being 3 full chassis of AMD blade servers.IMHO, its now a two baron world with a missing king, each with strenghts and weaknesses.

>IMHO, its now a two baron world with a missing king, each with strenghts and weaknesses.Yes I back that opinion.
Woodcrest is hampered by its FBDs. While it delivers much better bandwidth, it has worse latencies. Furthermore the 4 MB L2 cache & Core2 prefetch does not help that much in a multithreaded server environment, than in the average desktop application area.
What I want to say is, that the performance difference between Conroe/Athlon64 will be bigger than that between Woodcrest/Opteron.
First "tests"( I was told by an administrator of a huge financal institute) also showed a Woodcrest performace lack with gcc compiled 64bit applications. Are some of your applications 64bit, too ? It would be interesting, to get more 64bit statments. For some reason, there are none from Intel so far ...

Yes, I've been wondering about 64-bit performance too. Intel hasn't mentioned it with a word, but I hope they've made a decent implementation this time around.duploxxx - Thursday, July 13, 2006 - link
no they didn't, still the same as in the Netburst. some small 64bit testing has been done on XS forums seeing a core architecture gaining 17-18% performance on a 64bit os + program like 64bit cinebench. the opty 940 gained 31-38%
