An Easy Way to Calculate Athlon XP P-Rating

[Swordfish]

Simple way to get the clock or p ratings for athlon XP's...

http://www.ocinside.de/html/workshop/p_rating.html

check it out...

btw are the values correct?

Well it doesn't support Bartons but generally it seems about right yeah.
Nice link!:t

it reported my 2600+ as 2133MHz (266MHz fsb), I have a 2079MHz 333MHz fsb version ...when I type in the correct MHz it reports as 2500+.

geez... just do the old MULTIPLICATION TABLE

clock x bus = mhz (rounded cpu speed)

you mean (multiplier x bus) = actual speed...

PR is just what it is supposed to compete with and destroy.

... PR is just what it is supposed to compete with and destroy. PR is ...according to AMD... supposed to reflect the equivelant speed of an original Athlon, not a Pentium. This is explained in the "XP Processor Benchmarking and Model Numbering Methodology (http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/Benchmarking_Methodology2_v2.5.pdf)" white paper (page 6).

AT last confirmation that i am runnign an XP2900+

So what does it do with the clock speed put in to turn it into a PR? Is there some formula for it?

[Swordfish]

check the source of the page...you will c a script

this is some of it...

<SCRIPT LANGUAGE="JavaScript">
function showrating()
{
var chkit = "";
if (navigator.appName == "Netscape")
{newmhz = document.ratinginput.mhz.value*1;}
else
{newmhz = document.ratinginput.mhz.value*1;}

if (isNaN(document.ratinginput.mhz.value) || document.ratinginput.mhz.value == ""){chkit = -1;}

if (chkit == -1){
alert("Please just type in the numbers !");
document.ratinginput.mhz.focus();
chkit = "";
return false;}

if ((chkit != -1) && (newmhz >= 1333) && (newmhz <= 1989)){
ratingvalue = (Math.round(((newmhz*1.5)-500)/100)*100)+"";
document.ratinginput.rating.value = ratingvalue;
}
if ((chkit != -1) && (newmhz >= 1990)){
ratingvalue = ((Math.round(((newmhz*1.5)-500)/100)*100)-100)+"";
document.ratinginput.rating.value = ratingvalue;
}
if ((chkit != -1) && (newmhz < 1333)){
ratingvalue = "NA";
document.ratinginput.rating.value = ratingvalue;
}
document.ratinginput.mhz.focus();
}

function showmhz()
{
var chkit = "";
if (navigator.appName == "Netscape")
{newrating = document.ratinginput.rating.value*1;}
else
{newrating = document.ratinginput.rating.value*1;}

if (isNaN(document.ratinginput.rating.value) || document.ratinginput.rating.value == ""){chkit = -1;}

if (chkit == -1){
alert("Please just type in the numbers !");
document.ratinginput.rating.focus();
chkit = "";
return false;}

if ((chkit != -1) && (newrating >= 1500) && (newrating < 2400)){
mhzvalue = Math.round((newrating+500)/1.5)+"";
document.ratinginput.mhz.value = mhzvalue;
}
if ((chkit != -1) && (newrating >= 2400)){
mhzvalue = Math.round((newrating+600)/1.5)+"";
document.ratinginput.mhz.value = mhzvalue;
}
if ((chkit != -1) && (newrating < 1500)){
mhzvalue = "NA";
document.ratinginput.mhz.value = mhzvalue;
}
document.ratinginput.rating.focus();
}

</script>

with a little bit of rewriting the code it can be made to display the correct values.......well the writer did a good job of it until barton came out and the modified p-rating afterwards.
