Geometric Processing Units? The "magic" of this renaissance in GPU processing seems mostly to just be the (maybe unsurprising) versatility of Euclidean Geometry to a wide variety of problem domains.
Parallel Processing Units?
Hyper-Parallel Independent Processing Units?
Standard Hyperparallel Integrated Technology?
I do so love fun with acronyms...
Vector Processing Units
It does a good job of communicating their main functionality.
