The benefit is that GPUs can give you far more floating point operations
per buck and second than CPUs.

The drawback is, that's only true as long as you're performing the same
sequence of operations on a vast number of data points in parallel. As
soon as any data points need special treatment, the other data points'
computations need to be stalled. So programs need to be written in a
matter that minimizes such special handling.
