Re: Twice the memory in that DELL submission, for one thing. Twice the memory leads to >2x the performance, Petz? I don't think so. What's your next theory? Re: But would a real user turn off hardware prefetch to get better benchmark scores, even though it helps most other applications? Sure they would, if they were buying a Java applications server. And otherwise, why would they care about SPECjbb2005? It's like SPEC_CPU, Petz. Lots of compiler optimizations enable the top scores you see in this benchmark, both for Intel as well as AMD. You guys like to argue that you should only compare non-optimized scores, since no one uses optimizations, but if that were the case, why would the industry spend billions of $$ to optimize code so that it runs faster, and why would Intel spend (at least) hundreds of millions of $$ to build a software and solutions group that facilitates ISVs in optimizing their software so that it runs well with Intel platforms, if this did not have a positive effect on sales...? Think, Petz. These optimizations do make a difference, and people sure as hell use them! Re: If Anand used a "whacked configuration," how come it didn't mess up Barcelona performance? I didn't claim this. I'm sure Barcelona performance will also score much higher when using OEM optimized configurations. But no one has bothered to post these scores, and like I showed you earlier, Dell is "de-emphasizing" AMD due to disappointing performance on Barcelona and Phenom. I'm sure internal server testing had a lot to do with this. Dell doesn't base their corporate decisions on results from Anandtech. Re: Hey, but I know you are just echoing DougSF30's PM to you, but he also just said that Anandtech lied. I don't think Anand lied about anything, nor do I think any of these sites (maybe with the exception of Tom's Hardware Guide) is on the payroll of either of the CPU vendors. They assemble a test case, run the system to the best of their ability, and then attempt to frame a conclusion that fits their data. But in the end, they're only human, and even the writers at Anandtech make mistakes. There's no arguing that Dell can post a much greater score in SPECjbb2005. It's posted on a public website for all to see, and the SPEC website has a certain level of enforcement that configurations and scores are legitimate. So unless we see it pulled in the near future, I would claim it's trustworthy. Anandtech, to their credit, is a fabulous enthusiast site, and often time comes up with excellent reviews and articles. But in this particular case, the data is conflicting, and I will choose to trust the SPEC results over the Anandtech results. It's just as simple as that.
