Prepare to spring. There are presently dual processor motherboards on the market, so the 'proof of concept' has been ironed out for decades.
AMD has announced a dual core chip that is coming out next year. I am not at liberty to discuss this more than what is published here . But to paraphrase someone who would indeed know what he's talking about (despite my disdain for the man, personally)
One of the most powerful things next year is going to be our dual-core product. To me, that's going to really shock the hell out of everyone, because it's going to be hardware-compatible, infrastructure-compatible, pin-compatible. I mean, people that have a 2-P system can slap in a dual-core product and end up with a 4-P system for the price of a 2-P.
Thanks for the feedback on the hyperthreaded CPUs.
