CPU "IPC"??? Low end CPU's can't match high end CPU's at the same speed??
I have been trying to learn more about the "IPC" of CPU's.
this is only something I have read about here, and on some other forums, where people have stated.
that a low end CPU, say a XP 1700, has a lower "IPC", then say a XP 2100, so when the 1700 is at 2ghz, and the 2100 is at 2 ghz.
the 2100 will still be faster, cause it has a higher IPC rating the the lower end XP 1700....
atleast thats what I understand of this.
this next part is pure speculation, so please bear with me.
we all know the AMD's do 9 calcuations per cycle or something like that.
but say, the xp 1700 does 10 instructions per calculation, that would be 10x9=90.
then say 12 instructions per calculation, that would be 12x9=108.
thats just pure speculation for me personally to explain what the "IPC" may be, and how it may affect the CPU.
of course that part is simply speculation, cause I don't really know...
but it helps me understand, why people say, a lower end CPU will not beat a higher end CPU, even when at the same speed.
can anyone, shed some light on this?
I really want to learn about this in more detail.
just, after a few hours on the net, didn't really help to shed any light on the subject, and although I emaild AMD, they were of little help.
