<DIV><FONT size=2 face=Arial>The <FONT color=#ff0000><B>PR</B>

class=mw-redirect title=AMD href="http://en.wikipedia.org/wiki/AMD"><FONT
color=#ff0000>AMD</FONT></A><FONT color=#ff0000> </FONT>in the mid-1990s as a
method of comparing their <A title=X86

<P>The<FONT color=#ff0000> first use of the PR system was in 1996<SUP

title="This claim needs references to reliable sources from June 2010">[<I><A

class=mw-redirect title="AMD 5x86"
href="http://en.wikipedia.org/wiki/AMD_5x86"><FONT color=#ff0000>AMD
5x86</FONT></A> processor was as fast as a Pentium running at 75 <A
class=mw-redirect title=Megahertz
href="http://en.wikipedia.org/wiki/Megahertz">MHz</A>. The designation "P75" was
added to the chip to denote this.</P>
<P>The letters PR stood for "Performance Rating", but many people mistakenly
thought it stood for "Pentium Rating", as the PR was often used to measure
performance against Intel's <A class=mw-redirect title="Intel P5"
href="http://en.wikipedia.org/wiki/Intel_P5">Pentium</A> processor.</P>
<P><FONT color=#ff0000>Later that year, </FONT><A title=Cyrix
href="http://en.wikipedia.org/wiki/Cyrix"><FONT
color=#ff0000>Cyrix</FONT></A><FONT color=#ff0000> also adopted the PR system
for its </FONT><A class=mw-redirect title=6x86

These processors were capable of handling business applications under <A
title=Microsoft href="http://en.wikipedia.org/wiki/Microsoft">Microsoft</A> <A
title="Microsoft Windows"
href="http://en.wikipedia.org/wiki/Microsoft_Windows">Windows</A> faster than
Pentiums of the same clock speed, so Cyrix PR-rated the chips one or two Pentium
speed grades higher than clock speed. AMD did likewise with some versions of
their <A title="AMD K5" href="http://en.wikipedia.org/wiki/AMD_K5">K5</A>
processor, but abandoned the system when it introduced the <A title="AMD K6"
href="http://en.wikipedia.org/wiki/AMD_K6">K6</A>.</P>

<P>Itariu, kad procai jau anksciau tiek AMD (tarkim 1996), tiek Cyrix (tarkim
1995) buvo isleisti.. <BR>o paskui tiesiog nauja partija
"pervadinimo/perzymejo" (abu 1996m., wiki sako AMD pirmas paxalturino).. </P>
<P>Tuo labiau AMD pakepe 133MHz (is esmes 486-uko..) -> P75 (atitinkantis
486-ukus, ar tuos 5x86), <BR>o Cyrix'as jau reitingavo 6x86 (atitinkantis
"beveik Pentium".. pavadines jau 6x86.. AMD'ske su K6 taip jau nedare
berods..)</P>
<P>The <B>Cyrix 6x86</B> (codename M1) <..> was originally
released in 1996 ().<BR><..> It has six performance levels: PR 90+, PR
120+, PR 133+, PR 150+, PR 166+ and PR 200+. <BR></P>
