I got a little sample on the intel and AMD CPU's, if two computers with a pentium 4 in them. A computer that has pentium 4 with a bus speed of 133MHz and 512MB RAM is just as fast as a computer that has pentium 4 with a bus speed of 333MHz and 256MB RAM. It doesn't matter only on the clock speed, but if you want to know the performance comes from the L1 and L2 cache, memory bus speed, then the clock speed.

Intels processors are powerful indeed ... and very stable too
buuut they tend to get really hot haha .. and they suck energy abit more compared to AMD ... but still they're powerful

and AMD processors .. are energy saving, and very cool too .. and its has HUGE! overclocking potential *my LE-1620 is originally 2.4 ghz .. but I overclocked it to 3.2 ghz with proper cooling and bios settings* .. but its very unreliable ... after awhile your pc might shut down on its own even though you haven't overclocked it yet
i dunno maybe its just my power supply ... but I dont experience any random shut downs on my intel unit ..but! amd is cheaper haha

~_~ so uh ... I guess its safe to say that Intel are for hardcore gamers
and AMD are for overclocking enthusiast

haha AMD is fun!
