The SIMD execution units are also heterogeneous. Recall the SIMD execution units consist of SIMD functional units which perform MUL-ADD operations, special SIMD functional units which perform special operations such as sin/cos and SIMD load/store units.

In fact, there is also a (little-used these days) dedicated physics subsystem in certain Nvidia cards, adopted from the now extinct Ageia Physx board (I believe on newer cards this is just software, however - or it may always have been).
