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.

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."
24 hours have passed now, so where's the proper review you promised?!

Easy there, ss284. Try not to get the froth on your keyboard.Really, there's no foul play involved. It's just a series of poorly conducted benchmarks. People wouldn't've liked seeing a Xeon beat an A64 to begin with, and now that it's shown that the benchmarks are meaningless poor Kris is getting torn apart. Everyone makes mistakes... I'd advise just taking this review down before it festers, myself, but that's just my opinion.

Oh dang is that an AMD logo I see on anandtech's site? OH NOES! AMD IS PAYING OFF ANANDTECH! TIME TO START TALKING OUT OF MY ASS!Jesus christ will people stop accusing intel of paying him off? Muks75, you're an utterly useless and pathetic moron. Its pretty obvious you havent taken a look at anything between pages 1 and 13. Try reading the entire discussion before posting your useless crap here.

Seems like Intel is paying for the advertisements here. I am disappointed with AT, for such a pathetic comparison. And Kristopher, your post saying it did "pretty good for 500$ less" is the lamest excuse to defend the utterly useless comparison you have done.MrEMan - Wednesday, August 11, 2004 - link
#232 stated:"I praise AMD for bringing 64bit cpu's to the home user but any business in their right mind would never purchase a clone/emulator cpu as of AMD.".
Based on your comments, I guess most Intel-only businesses must not be in their "right minds".
As for X86-64, AMD is the innovator, and Intel is the cloner. It is the Itanium (which is the emulator of the two CPUs) which is most likely going to die or at the very least be severly as far as sales go. As a reminder, many of the Athlon64/Opteron engineers worked on the DEC Alpha, which has a great reputation.
The articles I have read stated that board manufacturers really dislike BTX and that DDR2 will be implemented by AMD when there is an actual performance reason to do so (now the only thing that DDR2 increases is the cost).
As a reminder, you are getting much greater performance (per $) out of your Intel-based systems because AMD is forcing them to cut their huge profit margins and actually get back to competing based on value (performance per $) delivered.
As for the review, I totally agree with those who stated that the article should have been pulled mainly because the conclusion has not been corrected since it was based on BS testing methods.
I will be curious to see what Anand's view of this fiasco is when he returns.

It appears to be about some bogus benchmarks, particularly John The Ripper. The program looks to Intel in the code. We've seen that trick before in benchmarks so no wonder a lot of people are skeptical.ALSO, the REMOTE location of the Intel server. Which, for some strange reason has never been dilvulged, yet we are supposed to take the word of the person in front of the "remote server"?

Intel has the knack to intoduce System packages much before they are market ready....Rambus & i820 are few things that went haywire.... If they try to rush things like this DDR2 will be just where RAMBUS went...in the dustbin

porkster - "any business in their right mind would never purchase a clone/emulator cpu as of AMD"I disagree. I think Intel made the smart move in copying AMD's x86-64. While obviously their first chips will perform at a substantially lower level, I'm confident that they will have some excellent designs out by 2006.
"I'm a programmer and also want future ready items like PCIe, BTX design, DDR2"
Huh? What does one have to do with the other?
As to being "future ready", BTX looks to be nearing an early retirement...DDR2 is more expensive without any appreciable gains yet...and PCIe has not shown any improvements yet (though it will be much more important to a platform that doesn't have Hypertransport...)

to 236:He he, he's probably not a programmer. What does BTX have to do with programming. It's just a form factor, and some are arguing that the only reason it's been brought to the market is to make sure that components are rearranged in a way that will ensure Prescotts and other new chips get good enough airflow inide a case cause they're too runnig too hot.

#232: Your comments about not wanting an AMD chip because you are a programmer confuses me. I am also a programmer and I bought my A64 3000+ because of that. A64's excel in our work evironment e.g. Code Compiliation, Web Serving, Database serving etc.... Why would you choose an inferior product? How does PCIe help you write better code?
