I just read this on AMD's website, and then I noticed a link to something by AMD - The top 10 reasons Intel did not participate in the Dual-Core Duel. 10. Tried to follow their roadmap to get to the duel. 9. Decided to take the "front-side-bus" to the duel; got stuck in a bottleneck. 8. The "Intel Inside" stickers they used to package the cores together keep melting. 7. TO busy rearranging the chairs on the Itanic. 6. "Hey we don't expect anyone to actually buy these things!" 5. Didn't want to comete when the realised that the dual would involve actual "rules" of fair competition. 4. They couldn't get a permit from the fire department to emit that much heat. 3. No systems available yet -- protective clothing used by manufacturers only safe for up to 149 watts. 2. Dell told them they weren't allowed to participate. And the number one reason Intel didn't accept the dual-core dual: 1. Moore's Law has been replaced by "Paul's Paradox": the number of cancelled products per year at Intel will double every year after the introduction of the AMD Opteron Processor. (Link to the pdf file of this is here.) I laughed when I read that, I round it rather amusing.
I read that a while back, another Intel one... Why Apple chose Intel for its CPUs: Most of Apple's customers live in colder climates.
