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.

Agreed!I'm not interested in 32 bit performance.
If you're gonna be spending this much money on an upmarket system you better be running it in 64 bit mode. I know I will.
So if Opteron benches better than Woodcrest in 64 bit mode that changes the equation for me.
Also isn't Opteron 290 out any time now? The would close the % gap a little because of the higher clock speed.
Also S1207 Opterons will be here 1st August. The new nforce5 based pro/server chipsets might give a little boost over existing ones too, as could the bandwidth boost and lower power of DDR2.

Check the review, this (and previous Linux review) uses only 64bit software.

Oh indeed, x64 Windows was used.Good to see than, that woodcrest doesnt take a 64bit penalty. Maybe the Linux application of my source uses FP calculations and no SSE, or it is due to the compiler which may be in favour for Intel on the windows. Anyways 64bit is a big "playing" field for benchmarks looking forward to read more ;-)

Slightly better performance and slightly lower power consumption. Looks like you have a winner for new servers.However, for a Fortune 500 company, there are other things much more important than slightly better performance and slightly lower power consumption.

After the poor showing of NetBurst Xeons against Opteron, I'd think any Dell shops would be thrilled to regain the performance crown. Also, frankly, a 5-10% lead is about all most things get you these days, especially when I/O and everything else comes into play. The Woodcrest systems have better overall CPU performance, but it often isn't that important when working on massive databases.Incidentally, from what we've seen of Conroe, it seems like Intel could release Core chips at up to 3.4-3.6 GHz without difficulty right now. Rather surprising, given the 14 stage pipeline vs. 39 for Prescott.

Actually its not a big thrill at all. One of the major pushes at the firm is to consolidate into VMware based servers or larger raw servers but in all cases stop the traditional 1 server per application that seems to affect most firms. Therefore we are more focused on 4 socket 8 core style servers i.e. HP BL45 blades than 2 socket blades. We had all the top level Dell executives coming in trying to convince us to stay with Dell because at this time, they have no answer for the larger server (the Oct/Nov timeframe for the Dell 4 socket AMD server is too far out). So in the short term we will be a hybrid Dell/HP shop. Maybe we will shift back if Dell's commitment to AMD indeed ramps as expected.Dubb - Thursday, July 13, 2006 - link
I doubt this has much practical use, but I am nonetheless curious...could you "pinmod" a cloverton to run 1333 FSB?might make for some speedy rendering if it was stable.
Kiijibari - Thursday, July 13, 2006 - link
No that is not possible, dont you think that intel would release it, if it would be possible ? Just think about it, to lower the FSB bandwidth on the 4core part doesnt make sense, does it ? 4 cores are much more bandwith hungry than 2 ..Reason is the "Intel bolt-together" architecture. The 4core part is just 2 Dies in one package, thus it will have twice the bus load of a single (dual core) CPU. Intel did the same already with Netburst dual cores, hence you have the same FSB limitations there.
All in all it is a little bit odd, Cloverton/Kentsfield performance increases will be much less than linear, but Intel has the advantage of time to market vs. the AMD K8L quad core. Though AMD's QC design looks much more sound I expect intel to be 1st with releasing a quad core CPU.

okaaaayyy...cloverton's platform supports 1333, and the kentsfield ESs run 1333 easily. most clovertons probably CAN, it's just a question of if the 1066>1333 pinmod some have suggested for dempsey or 1066 woodcrests actually works, and if so, clovertons might be an interesting application of it.
I'm just curious, is'all.

It may work, however that kind of overclocking is more dangerous than normal overclocking. It is easy to oc a chip that run at, lets say 2 GHz, and there is e.g. a 3 GHz top model. Chances are good that yields are well, thus your 2 GHz model may be able to run faster as most models pass 2.6 GHz tests, thus your model was just down binned to 2 GHz.However with the FSB1066 vs. FSB1333 I assume that you are playing around at the absolutly maximum. Intel would do everything to raise FSB speeds, exspecially with Quad cores. It is nonsense from the performance point of view, to decrease the available bandwidth while the number of bandwidth consumers (i.e. cores) increases.
It might boot & work with a FSB1333 though, but Intel cant and wont gurantee that. It may be good enough for Super Pi or other "fun stuff", but if you run I/O intensive applications, cross your fingers and be prepared for data corruption.
