This is wrong. The rate of integer and logical instructions that can be run per clock is equal to or higher than floating point instructions. For example, AMD GPUs 5-way VLIW units can execute, per clock: 5 integer/logical op, or 5 single precision flop, or 1 double precision flop. Nvidia GT200 GPU streaming processors can execute, per (shader) clock: 1 integer/logical op, or 1 single precision flop, or 0.5 double precision flop.
