- : 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 (?)
-
- 603 might not be faster then a 060 mhz per mhz, but defenetly as the
- edge for float operation.
-
- : 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.
-
- That sound better...

-
- : 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.
-
- I didn;t even know the 150mhz pentium was out... already the 133mhz version
- is ~600$, and with intel prices I expect the 200mhz version to be priced
- > 1000$ . The new macs using the 604 are near the 5000$ mark, do you know
- how much of that price goes to the cpu? I hope escom can produce a 604
- class machine for <2000$
