Well the
9 series chipsets are are somewhat interesting and the first generation where moving over. the second generation worked out all of the bugs and supported dual core, the third generation i'm not really sure whats useful yet.
Also Intels system makes plenty of sense
x20=2.8ghz CPU
x30=3.0ghz CPU
and so on
if it is a 6x0, 8x0, or 5x1 cpu it is 64bit.
if it is 8x0 or 9x0 series it is dual core.
if it is a 7 series it is a dothan.
that might seem like alot stuff to remember but its not like AMD where a 3800 could mean several things 2800 means several things, 3700 means several things. Intel may have more numbers but it is possible to understand them and they all have significance.
Also by posting anything in this thread its kind of like asking for a flame war which if you want it please do somewhere else.
