CJ, Re: AMD does a better job on the speed of their SOI process. They are currently shipping 1.8GHz with a processor that uses a 12 stage integer pipeline with several of those stages devoted to dealing with x86 stuff, which the PPC970 doesn't have.
LOL. Yeah, that's a great SOI achievement, especially considering that their bulk CPUs have a 10 stage integer pipeline that can currently scale to 2.2GHz on 130nm.
Re: Yet the PPC970 is slated to top out at 2GHz at 130nm. AMD likely can do better than that with a considerably shorter pipeline.
You're comparing apples to oranges. AMD uses plenty of custom circuits in their implementation to achieve their clock frequencies, while IBM does not. This has been confirmed by several sources, if you check around a bit. The point is you cannot compare the two frequencies on different designs and draw any kind of conclusion about the process, since the design has just as much to do with it.
