will PPC64 .zip file work for all aix 5.3, regardless of processor types?

i see on the oracle.com site, under 11.2 downloads, a file described thusly,

AIX (PPC64)                       Disk 1, Disk 2 (2.2 GB) | See All (Including Client, Gateways, Grid Infrastructure, more). 

my concern is whether this indeed the download for me.      i'm running aix 5.3 under unix, yes.   

but  my company has three different computers upon which i would like to install 11.2.   all are running aix 5.3 under unix.

two of them run POWER4+ processors, which appear to be an evolution of the PowerPC processor.   however, the thirs uses an RS64-II processor.
