Linux and EM64T; Intel's 64-bit Suggestion

Synthetic Benchmarks (continued)
TSCP
TSCP is a simple chess program, which you may read more about here. We compiled the program using our own Makefile, which you can download here. Once compiled, we ran the "bench" command inside the program. Using the -m64 flags provided no change in performance.
As you can see, there appears to be no advantage with HyperThreading for this application. This also appears to be the largest lead that the Intel processor takes over the AMD during the duration of our analysis.
Update:We have retested this part of the benchmark with the -O2 flag in the correct place for both machines. The score has changed to reflect this. br>
ubench
Finally, we have ubench, which stands as the definitive Unix synthetic benchmark. Feel free to learn more about the program here. We compiled the program using ./configure and make with no optimizations. The benchmark was run on a loop ten times to assure that we were getting a true average.
Here, we see HyperThreading working against the Xeon processor in a distinct fashion. According to the Ubench website, both of these machines with single processors outperform dual Xeon 2.4GHz machines, even though they are only running on one processor. The program runs several math-intensive floating point and integer operations over the course of three minutes.

Which tests were re-ran? I guess I should ask that first.KristopherKubicki - Tuesday, August 10, 2004 - link
#203 can you be more specific? What is wrong with my conclusion.Kristopher

What more do we want? Fix the rest of the article, including the conclusions you drew.KristopherKubicki - Tuesday, August 10, 2004 - link
#200:Jasons article is seperate from mine. His is running on windows anyway with two processors.
"f-off people" is strictly not my attitude. I have made changes to the article that were suggested; i fixed the broken makefile, i even did another article on my vacation with an opteron 150 to be posted within the next 24 hours.
What more do you want? Really?

There is nothing wrong with an engineers’ pov. We tend to like symmetry and base results on facts. Unfortunately there is little symmetry and too many variables for accurate results.Experiments should be kept in the lab

A few days ago when Nocona was announced I shouted I wanted some benchmarks.When Jason Clark mentioned AT is working on some benchmarks I was very excited. Now I am am not. This article is... well in attempt to be polite... of a very questionable quality or simply crap.As many people posted their observations, whith most of which I agree, this is not quality we're used to from AT. And all the AMD and Intel fanboyish escapades in here are just making all this worse.
I feel like something should be done. I have no idea what but just one 'f-off people' type of comment from the author is just not doing it for me. This is bad.

Good on ya Kristopher, you got a bit of scientist in you unlike some of these machine like engineer types. Some of us know where you are coming from (and it aint Intel). A little knowledge can be a dangerous thing but its still better than no knowledge at all. Looking forward to your later articles on the subject.MikeEFix - Tuesday, August 10, 2004 - link
Well the nvidia 250 reference board isn't exactly a Tyan Thunder K8W(S) either.The Xeon is using platform $600.00 server mainboard while the desktop variant, a64, is using the generic desktop solution.

This is the kind of article i'd expect from Tom's not Anandtech. I guess Anand is out with the lady.srg - Tuesday, August 10, 2004 - link
Well with these refinements an updates to the benchmarks, not forgetting setting them up right, the gap is closing to what I would have though it would have been, although the Jon-The-Ripper benchmark does seem odd (explained better my an earlier poste, if he's right then the 3500+ is basically running 64-bit'ised K6 code).I think what Kris has learnt here will be valuable for later reviews (and no, the simple fact that Intel beat AMD won't bring a torrent of flames like this one).
