Pentium PC
8080: Eight bit machine with 8-bit data path to the memory.
8086: 16 bit machine with wider data path and larger register and
instruction queue that prefetch a few instructions before they are
executed.
80286: Extension of 8086 enabled addressing 16MB memory
instead of just 1 MB.
80386: 32 bit machine support multitasking meaning it could run
multiple programs at the same time
80486: Introduce the use of much more sophisticated and
powerful catch technology and sophisticated and instruction
pipe-lining.
Pentium: Pentium introduce super scalar technique which allow
multiple instruction to execute in parallel.
Pentium pro: Super scalar organization with aggressive use of
register renaming branch prediction.
Pentium 2: Design to process video , audio or graphics data
efficiently.
Pentium3: Support 3D graphics software.
Pentium 4: Includes enhancement of multimedia.
Power PC
601: 32 bit machine
603: Also 32 bit machine comparable in performance with 601. But with lower cost more efficient implementation.
604: 32 bit machine uses much more advance super scalar design technique to achieve greater performance.
620: 64 bit machine including 64bit register and data path.
740/750: Also know as G3 processor integrates two levels of cache in the main processor chip.
G4: Increases parallelism and internal speed of processor chip.
