Not the speed tests, but the Titannuim Powerbook memory bus was reported to
be on 100-200 MHz, and the information capacity to 1-2 GB/s (but I do not
recmeber the details anymore). This gives a shuffle of 8 * 1-2 GB/s /
100-200 MHz or somewhere in the middle of 64 to 128, per time. But perhaps
the figure 1-2 GB/s does refer to someting else than the memory informatin
low (I do not remember).

I recall I looked there too, for the G3, a long time ago, but I could not
find details about memory bus size.

I found it at a mirror (the address above was overloaded, so I could not
check it there).

Thank you for the URL. (I knew that it is available under MacOS X.)
