Today, the hype about dual-core processors is so widespread that the understanding of the technology seems to be out of the truth. Both AMD and Intel compliment the merits of their dual-core processors on their web pages. Their campaigns are timely, as most industry watchers believe the dual-core processors will be in the pipeline in 2006. But there are some st

Dual core vs. Dual CPU: AMD and Intel's dual-core technologies also have a very different physical structure. AMD has two cores on a die (crystal), connected through a direct-attached structure, higher integration. Intel would encapsulate the two cores placed on different die (crystal), so someone called Intel's solution "dua

Now when it comes to processors, the word "double core" should inevitably be talked about. Looking at the full street dual-core processor ad from Intel Corporation, no one would suspect that 2006 would be a dual-kernel processor. But from the various reports of the relevant dual-core processor, I find that many of the places are inaccurate and misleading to consu
