Optimization for Duron 1.3 Ghz

momotaro · Post by **momotaro** » Mon Sep 04, 2006 6:24 pm

For my Athlon XP 2400+ I use CPU=athlon-xp for code optimization.

What parameter is neccesary for a Duron 1.3 Ghz?

If you are using Windows, use Zget to get an answer.

If you are using Linux, compile archopt in the tools directory and run it to find the answer.

In Linux by default it uses archopt, just build.
That duron is probably athlon-tbird, but zget, Linux building, or archopt will tell you.

zget 4 say --> athlon-xp

is not better "athlon" than "athlon-xp" ?????

monotaro... I meant that you want to use Zget 4 on the machine you are compiling to (the Duron, not your Athlon XP)

Most likely, you should target the Athlon, since Durons at those speeds do not have SSE and compiling for an Athlon-XP and loading it on your Duron will probably cause a crash.

If running zget 4 on your Duron says athlon-xp, then athlon-xp is what you want to use.

I think you have an athlon-tbird at that speed though.

If running zget 4 on my PC with Duron says athlon-xp (a bug?)

Tomorrow will test the 2 different compilations (athlon-xp and athlon) for possibles "errors".

Reading this...
http://en.wikipedia.org/wiki/Duron

It probably should work. I was thinking Athlon-Tbird, but these Durons at those speeds do have SSE.. so Athlon-XP is appropriate. IIRC, the Durons of the SSE (Athlon-XP) generation are just L2 cache crippled Athlon-XPs...

No, it's not a bug, if that's what it says, that's what you have.

ok ok, now understand, the core of a Duron at 1.3 Ghz are based in the Athlon-XP core, and the optimization is for the core

but L2 cache and FSB are minor.
