FLOPS stands for for FLoating-point Operations Per Second. For programs that make heavy use of floating point number, such as scientific calculations, this is a better measurement than Instructions Per Second (IPS), as floating-point operations are more complicated and require more instructions.

Floating point operations are implemented by single instructions on essentially all modern processors. In this diagram for the GTX 480, each yellow box can perform a 32-bit floating point multiply-add operation (result = a * b + c) in a single cycle.
It is true that a floating-point ALU certainly more expensive to build than an integer ALU in terms of chip area -- more transistors -- and in terms of power consumption during operation.
What is FLOPS here? anyone could please explain?
