Linux and EM64T; Intel's 64-bit Suggestion

Synthetic Benchmarks
Our Nocona server was setup in a remote location with little access, so we had limited time to run as many real world benchmarks as we are typically accustomed to. Fortunately, there are multitudes of synthetic benchmarks that we can use to deduce information quickly and constructively.Sieve of Atkin (primegen)
Primegen is an older, but still useful library for generating prime numbers in order using the Sieve of Atkin. We compiled the Bernstein implementation by simply running "make". We ran the program as so:# time ./primes 1 100000000000 > /dev/null
We found the benchmark to be extremely reliable and we replicated our figures continually with less than 1% difference.
Super Pi
We ran the Linux compilation of Super Pi 2.0, which is a closed source application. We are not aware of which optimizations are compiled with the program and we are prohibited from redistributing the binaries. Please download the latest binaries from ftp://pi.super-computing.org/Linux. We ran the command:# ./super_pi 20
Below is the program's output of calculation time in number of seconds.
After re-running the program several times, our benchmarks never deviated outside of 1%. In a mathematical operation-only situation, the Intel processor has outpaced the AMD offering twice now.

I will admit, i am an AMD fanboy, i was loyal to AMD since the k6-2 days. I ran AMD when intel was stomping us... Now we get a better product, and this, A review comparing a Desktop pc processor. with the very best that intel can pull off. and it only manages to win by a few.. Compare it to an opteron 250, i do belive the 250 will bench 2 or 3 times more than this new intel, It is good to see competition. But, is it really worth trying to glorify sub par technology.KristopherKubicki - Wednesday, August 18, 2004 - link
TauCeti:EMT is some medical something. EM64T is the actual terminology.

Oh dear. I'm sorry to say that this review is so full of conceptual and methodological holes that I can almost hear generations of scientists, reviewers and geeks in general turning in their graves.Does anandtech have no peer review procedure? No one checks articles before they are published? It's such a shame, because this has made me think twice before accepting what I read here as objective fact.

Just wondering, is 270 comments (not counting this one) a record?dark0n3 - Thursday, August 12, 2004 - link
I see lots of pro-AMD comments here, but I think noone noticed one issue about this test that might make intel scores look worse than they really are.Because Xeon's pipelines are much longer than pipelines in A64/Opteron, their performance is more dependant of optimizations. And from my experience, gcc does not produce binaries that have comparable quality to binaries that any windows compiler produce. (and disabling all optimizations in some tests...) I wonder how results would look, if programs were compiled with intel's linux compiler instead. See performance delta on windows for reference [gcc vs icc]: http://www.aceshardware.com/read_news.jsp?id=75000... I'd expect same ratio to apply in unix benchmarks.

Hi Kristopher,"What the heck is an EMT64? "
Because Intel changes terms for the AMD64 emulation mode every odd hour, YOUR test-system.os vendor ( SuSE 9.1 Pro) decided to stick to the EMT64 nomenclature.

Not that it matters a lot...

Yep, pretty stupid idea for this review. I have an old bicycle, why not compare it to EMT64... Ohh wait here is another great idea for the review: "What tastes better, EMT64 vs LCD TV vs Scroll wheel from the mouse?".... I guess I could continue like this for a while.Man do you really have so much trouble figuring out what to review?
