Hi. Am just curious. I have read that some of the AMD CPUs for ex: An Athlon II Triple Core has actually 4 cores with 1 disabled, A Phenom II dual core has actually 4 core with 2 disabled. Why they manufacture like that? They are simply wasting pure silicon and so much of the computing power right? Why they just can not manufacture perfect 3 or 'x' core CPUs? Please enlighten me.
