Download the RS/6000 Product Handbook from redbooks.ibm.com. It will
probably answer most of these questions.

Thanks for the responses so far everyone. The 660 using the RS64 IV
processor and the 630 uses the POWER4. What are the major differences
between the two? Links or .pdfs would be appreciated also.

The H50 is a PowerPC 604e, is that the same as the RS64 III (thinking the
answer is NO)? Again, a link or .pdf that discusses the history of IBMs
processor architectures would be helpful. I have "IBM's Eserver pSeries
and IBM RS/6000 Facts and Figures" dated August 28th, 2002 which doesn't
discuss the H50 at all. Coming from an H50, should I be concerned with
what processor architecture is chosen (Power4 or RS64 IV)? I will be
running AIX 4.3.3 on any new box that is purchased.

Thanks again for any info.
