The PS2 was where this peaked. It has a weird multi CPU architecture with multiple CPUs and coprocessors, but was popular enough (dominant, really) that devs really invested in some cases. Shadow of the Colossus is a good example. They tried the same playbook again with the PS3, but paniced when they realized how hard the cell SPEs would be to program to execute shaders effectively and added an Nvidia GPU. The PS3 was not sufficiently more popular than the Xbox 360 to justify the level of investment to really capitalize on the unusual architecture.
