writes "AMD will be releasing triple-core chips next year, carrying the same Phenom brand name. Their real reason?
The three-core Phenom chip is basically the same as the quad-core one, it just has one less working core, Brewer confirmed. One disadvantage of the monolithic quad-core design that AMD chose for its quad-core chips is that just one manufacturing defect on part of the chip can knock out an entire quad-core processor. But if you invent a category for three-core chips, suddenly you can make money off those chips that would otherwise have to be discarded because of a defect that disabled one core. Reminds me of the 486SX more than a decade ago. Otherwise normal 486DX chips, with their defective math co-processor disabled."
