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'm have been a loyal anandtecher for quite a long time, if i keep seeing reviews of this caliber, i'm going to have to delete my bookmark.syadnom - Monday, August 9, 2004 - link
wow, WTF were you guys thinking!?!ANANDTECH
in our next review, we'd like to show your how an AthlonFX53 compares to a 2.8Ghz Celeron
........."as you can see, the Celeron just cannot keep up with the AMD monster, looks like intel is really going to have to pick up the pace or AMD could rule the frickin' world with this new behemoth"
--
really though, a Xeon3.6 vs. a A643500, WTF, where is the Opt 150? how about showing apples to apples, this is like comparing apples to bannanas.

This review was bizarre. Why compare a $345 CPU to a top of the line Xeon? An Opteron 150 is less than $700 from many retailers. What's next, Opteron vs. Celeron???Avalon - Monday, August 9, 2004 - link
lol Shimm."Xeon processor retails for $850 and the Athlon 3500+ retails for about $500 less". $500 less than the Xeon, not $500 :)
I agree, weird article to put up, and very weird benchmarks.

Kristopher:To reiterate what other people have been saying, your methodology is flawed. What you need to do is choose 3 processors from AMD and Intel (same class preferably) and run them both in an 32-bit environment and then 64-bit to see what the gain, if any, really is. For all we know the 64-bit scores for the Nocona might be even lower then the 32-bit brethren. If so this also points to the fact that most of the applications you tested are more megahertz dependant the 64-bit dependant, and not a good judgment of the how good Intel’s 64-bit implementation is. If the AMD is 64-bt scores higher then it does in 32-bit then this says that AMD did a good job and gets a boost, however if Intel’s chip falls compared to the 32 test this shows that Intel implementation is not good.

for real though, did intel pay you off for this review???and you state that a 3500+ retails for less than $500... why don't you try less than $400 at most online vendors...
and you'll do a review later (opteron vs. xeon)??? why don't you do in the first place instead of being a lazy bum and trying to save face for intel...

what in the world are you doing?is AT's review's getting worse and worse???
this by far has to be the worst review ever... comparable to those found at tom's...
kris... what in the world were you on when you did this review???

Wow!In other news: "intel's offers 10M for anandtech.com"

Is it just me or is a Server/Workstation CPU v. Desktop CPU comparision anything but apples to apples? Perhapse apples to pears at best? Could please re-run every test with the correct hardware? While I'm in a mood to rant, why the heck is your site no longer storing passwords when posting comments to articles?murdmath - Monday, August 9, 2004 - link
Why are you running a Server chip (ie Xeon) against a Desktop chip (ie Athon 64)? Get an Opteron 150 and do it right.
