Keeping the politics and personal feelings aside here, what is wrong with the PowerPC architecture? I know Motorola for years, and now IBM, has been having problems keeping yields up, why? The G5 was the world's most advanced processor and, what, 2 years later it's being practically abandoned in favor of a drastic architecture jump? IBM seemed so promising for future processors from the G5 and being able to delivery, what went wrong? I know that Intel, AMD, IBM and everyone else are all having the same issues....too much heat, power, etc.....what makes Intel the answer if they are having the same issues as IBM right now? The PowerPC, as I have understood, is generally considered superior, more robust, and better for many applications, especially scientific ones.....what has changed?
