here's the snippet from [H]ard OCP:
Here is an interesting statement from an AMD applications engineer that will remain nameless. This came to us second hand and was not supplied directly to us so I don't want to get the guy in trouble. First the questions posed:
Will PowerNow! be used for desktops, if so why? Will there be any new faster bus speeds so the Athlon/Duron can better take advantage of DDR Ram?
The specs for the desktop version of the Athlon 4 have not been finalized at this time, therefore I cannot answer this question. Support of PowerNow! will probably be determined by the industry and our partners. If there is a demand for this functionality, then it will probably be included. While I cannot think of very many reasons why this would be needed in a desktop environment, there may still be reasons for it. My guess is that throttling the clock based on CPU usage could make your processor last longer. After all, there is no reason to pump the CPU if it is not really being used.
As for faster bus speeds, the Athlon bus can scale up beyond the 266 that it is currently running at, however we would be back in the same boat with the memory bottleneck. Therefore, memory developers along with chipset companies are starting to work on DDR 2. The specs are still early in the stages of development so it is difficult to say what speeds they are talking about, but rest assured it is being worked on.
I can think of some HUGE *** REASONS that we will need it in the desktop segment if it works like I think it will. Of course, none of those reasons have anything to do with OCing the Palomino,
pretty interesting if you ask me, as to the reliability issue as of late with AMD based systems (the topic of several articles on the OC homepage), I think NVidia might be gearing up to silence critics (FYI- the CEO of NVidia is a former employee of NVidia, check it out at their website, it's listed with his bio/background info). This waiting stuff sucks... I'd kill to know what's going on in those R&D labs right now!
