It's actually a pretty poor fit for almost anything.  I think you're failing
to appreciate just how puny these cores (and their associated infrastructure)
really are.

If you do happen to have an embarrassingly parallel job, nVidia (or more
generally GPGPUs) have had the hardware for that for years now.
