The PowerPC G4 microprocessor has many powerful features,
including a pipelined system bus, called MaxBus, that is more efficient
than the system bus on the PowerPC G3 microprocessors.
The PowerPC G4 used in the iMac computer has the following
features:
- 32-bit PowerPC
implementation
- superscalar PowerPC core
- Velocity Engine (AltiVec technology): 128-bit-wide vector
execution unit
- high bandwidth MaxBus
- dual 32 KB instruction and data caches (level one)
- on-chip second level (L2) cache consisting of 256 KB with
a clock speed ratio of 1:1
