CNET News.com reports: "Just as the bragging rights for dual-core chip supremacy are dying down, Intel gave the first glimpse of a quad-core chip coming next year."
First there was the Megahertz/Gigahertz speed war with AMD to see who could produce the fastest CPU. Now, we are entering into the multiple CPU core wars, to see who can put the most cores on a chip.
The only problem with running multiple cores is just because you have the extra cores doesn't guarantee you a huge increase in speed. For example, the speed increase you will get going from one core to two cores will be much greater then what you will get from going from two cores to four cores.
