- PPC 603:
- one int, one float and one mem operation per cycle (sceduled)
- all instructions take one cycle except:
- int multiplication 5,6 or 9 c (depends on the operands)
- int divide 38c
- float muls double prec 2c
- float divide single prec 18c
- float divide double prec 34c (?)
-
- PPC 604:
- three int, one float, one mem per cycle
- I think (don't have a cycle table but heard "rumours") all instr
- take 1 c except the divide operations that are 1c faster than on 603.

- Don't know MIPS, but a 133 MHz 604 is three times faster than a
- 90 MHz Pentium (refering to BYTE), that is faster than the 200 MHz
- Pentium Pro.
