Floating point in TiBook?

The tech specs for the current G4 Power Macs include "Powerful floating-point unit supporting single-cycle, double-precision calculations." The specs for the G4 TiBooks do not mention this.



Is the G4 used in the current TiBooks lacking a floating point processor?

    The CPUs in the Power Mac and PowerBook are essentially the same (except for L3 cache IIRC).

    You can't get a modern computer that doesn't have full floating-point support in hardware. There are multiple pipes in a G4, but I don't know the details. When I was majoring in CS we were platform agnostic, and the G3 had only just been introduced. I know the Apple site claims AltiVec operates parallel to the main integer and floating units of the chip for a maximum of 16 operations per cycle of various kinds, though obviously one can't sustain that over every cycle.
