The Inquirer writes AMD is somewhat waiting on the launch of its 65nm processors before it can boost the MHz.
To be able to continue to make money against such a mighty foe, AMD has to focus on producing adequate quantities of processors without a large amount of waste. It can be a tricky balance, as AMD could pursue the almighty MHz with its process mix and achieve mind-numbing yields, or it could flood the market with chips at mediocre speeds with decent power consumption with incredibly high yields. These extremes are poor choices for AMD. But the bottom line for AMD and their success is simply process tech combined with a good design.
