GPUs for certain workloads are much more powerful than CPUs, meaning you can get stuff done much quicker. Machine Learning is one such field, batch-rendering for CG studios etc is another. You could throw 100 CPUs at something that perhaps 1 GPU might do in the same time (made up numbers but it gives you an idea of why people want it)
