Dell Test results

At the first three load points all platforms are within 4% of each other. At the fourth load point the spread opens up and Woodcrest leads the Opteron 285 by 5% and Dempsey 3.73 by 6%. Finally, at the fifth load point, Woodcrest is able to lead the Opteron 285 by 19% and Dempsey 3.73 by 27%. It is interesting to note in this graph, and other upcoming performance graphs, that Woodcrest scales linearly to the fifth load point but the others stop scaling linearly between the third and fourth load points.

Woodcrest is clearly the lowest consumer of power and leads the Opteron 285 by 11%-17%, and Dempsey 3.73 by 27%-33%. FB-DIMMs do consume more power than regular DDR2 memory, which partially offsets some of the advantage of the Core architecture.

When we combine performance and power and come up with Performance/Watt we get a very different picture. In this graph we see that Woodcrest is the clear leader at all load points and leads the Opteron 285 by 17% - 34%, and Dempsey 3.73 by 39%-88%. It is also interesting to note that the Opteron 280 outperforms the Opteron 285 on a Performance/Watt measure while Dempsey performance scales almost linearly with power. This often is an indication that the architecture is reaching its clockspeed limits, which is certainly the case as the only faster dual core K8-based chip presently available is the FX-62.

    Quite shocking to see Anand perform such a biased benchmark and get away so easily.

    Is it a coincidence that Dell did not sell AMD chips in their machines to date, and benchmarks from Dell show Intel chips perform better

    Can we say tuned or skewed

    It's just killing fan boys like Kiijibari that Intel is the best 2-way server out there now and they have to craft these elaborate scenarios to somehow justify how AMD is still great.

    Man give it up - Is it not enough almost every hardware site on the net has crowned Woodcrest the new 2-way champ over AMD? How much more evidence do you want?

    As I've posted before I own an FX-60 now so I don't feel great that Intel will soon be selling at Wal-mart a chip that will kick ass on my carefully overclocked FX system.

    But so what? It is what it is. Sure AMD are planning new things, and when and if they are benchmarked to be superior, then you can have your day again.

    For now Intel *owns* AMD except a couple niche segments - get used to it.

    i think you mean conroe... not woodcrest (the server chip) you can count the reviews on 1 hand that were made... two of them were from anand here. which are still in a large discussion about comparisson etc... and this one is comming straigth from intel...

    nice to see the "king" is anounced by intel themselves

    That prevented Intel's Woodcrest computers from being considered for government bids?">US government unit throws Intel out over RAID problems

    or">Conroe shows dodgy RAID performance anomalies

    I know its 'The Inq' but since this is a server test it would be nice to see some confirmation or exploration of this issue.

    The charts are almost totally inscrutable for the red-green color blind population, which is something like 5% of males. Learn to use a decent color scheme or incorperate symbol shapes as well as colors. Map makers know this...

    All of you ranting about comparing 3.0 GHz Woodcrest to 2.6 GHz Operton, look here:"> and see how much better Core 2 architecture is. Core 2 Duo 2.13 GHz beats Athlon FX-62 2.8 GHz in most benchmarks. Of course architecture is not everything, especially in enterprise market. Operton has advantage thanks to HyperTransort and advantage of Woodcrest is diminished because of FSB. But the main battle will occur with Desktops and here Core 2 Duo shines. Lets hope AMD will show something intersting soon, not only prices drop. All in all we consumers will benefit from this battle.

    you are looking at desktop... don't compare desktop with server... desktop is more the mass and low profit.... server and laptop are for the profit.

    AMD will manage to come out with a decent competetor in the next little while and we'll have real compitition in the CPU space again. I'm sure this sucks for AMD right now, and if AMD were able to rebound and deliver a competitor in the relitive near term futer for intel too. But for consumers, competition is beautiful, already we can look twards dirt cheap A64's for your low to mid-range computing needs.

    I tried skimming back through the article but is Anand just measuring the CPU wattage or the overall wattage draw for the whole platform (i.e. cpu, northbridge,dimms?
  • Jason Clark - Thursday, July 13, 2006 - link

    Wall folks, sorry that wasn't more clear. We'll ensure we include power measurement information in future articles. We use the same procedure as we've used in previous articles with power, an extech device and we log power througout the test duration.
