Second, most of the functionality of OpenGL does run on the GPU, so the capabilities of CPUs do not have much impact on the performance. The fact that integers are faster than floats does heavily depend on the hardware.

WebFor this reason, floating-point arithmetic is often used to allow very small and very large real numbers that require fast processing times. The result of this dynamic range is that the numbers that can be represented are not uniformly spaced; the difference between two consecutive representable numbers varies with their exponent. [1]

Some floating-point hardware only supports the simplest operations: addition, subtraction, and multiplication. But even the most complex floating-point hardware has a finite number of operations it can support – for example, no FPUs directly support arbitrary-precision arithmetic.
