MacCoaster:
Eh, 450mhz x 2 or 900mhz, not the same but pretty similar. It is common to refer to busses by their effective speed (533mhz and 400mhz for P4, 333mhz, 266mhz and 200mhz for Athlons), and so I am continueing to refer to the PPC-970 bus as 900mhz. I don't see how anything I said was wrong.
Note also that Arstech revleals that the bus runs at a fixed part of core clock speed (1/2), so that the bus is 900mhz only on the 1800mhz PPC-970. A 1.4ghz model would sport a 700mhz bus... with a data rate of "only" 622mhz, which means data transfer rate of "only" 4.9 GB/sec. This would work fine with dual channel DDR-333 even (oops, I meant DDR-166x2 ).
