I read today that quad-core mobile processors are in the making by Intel. I just don't get why. Do they offer a good processing advantage over faster dual-core chips? Do they save power? I have read that programmers haven't fully taken advantage of dual-core CPUs, so I just don't get the deal with quad-core. I'm all ears (well, eyes) for someone who knows more about the innards than I do to explain this. To me, it just seems like the old megahertz/gigahertz wars that really didn't amount to as much as AMD and Intel would've had you think.
