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.

Ooops... I really wish it was possible to edit these. =) What I meant to say was..."... especially since 2/3 of those benchmarks..."

I would like to see some Pentium 4 3.6 GHz numbers in there too so we can see the effect of Intel's x86-64 support. With the data available, it's impossible to decide whether Intel has integrated it properly and gets a performance boost, or if a 3.6 GHz Xeon is just naturally that much faster than an Athlon-64 3500+... especially since 92/3 of those benchmarks are not benchmarks I've ever seen you run before so I have no idea how ANY other processor compares.Sorry Kristopher, but this was a BAD article. There's not nearly enough information to draw any useful conclusions.

this was probably the worst comparison ever. At least give us some game benchmarks like UT2004 64bit and let us see some real numbers.Server CPU against a mianstream chip in a database environment will surely favor the xeon.
whatever though

what is the reason for comparing the new intel processor against the slowest socket 939 processor? why not a FX53 or 3800?DrMrLordX - Monday, August 9, 2004 - link
What the hell made you run a 3.6 ghz Nocona vs the 3500+?!? Try running it against an Opteron 150! For crying out loud . . .
