PyPy doesn't include a "JIT for NumPy": it includes a JIT for the
whole Python language, which can also work for Python programs that
use NumPy.  As far as I know you cannot run with reasonable
performance a complete, unrestricted Python program on a GPGPU.

Whether PyPy's NumPy will, over time, be extended to also support
GPGPU operations --- and whether this would then benefit from changes
to the JIT subcomponent itself --- only time and volunteers can say.


A bient=F4t,

Armin.
