  I know that there are some very early CUDA implementations for AMD GPUs
exist (maybe still only prototype?), but to my knowledge no implementation
is far enough along to allow complex CUDA algorithms like what is in
VMD and NAMD to run on AMD GPUs yet. Last I heard from someone working on
one of those implementations, there are a few things that existing
AMD GPU hardware doesn't implement that we use in NAMD, for example.

In principle the hardware features I refer to are things one could
live without, but they would impact performance.

Before I would advise someone to spend any time on looking for this or trying
it, I would expect to see AMD making much more noise about this themselves.
The last thing I heard that was public information was their announcement
last year at SC'15:

The only thing I have really heard since then was from someone working
on one of the prototype implementations asking about how to get around
CUDA features that weren't yet implemented so that they could start testing
our software. We responded, but I haven't heard anything since, so I would
guess we're probably still a ways out before something useful comes of this.
