I've only done the CUDA side (and not professionally), so I've always wondered how much those skills transfer either way myself. I imagine some of the specific techniques employed are fairly different, but a lot of it is just your mental model for programming, which can be a bit of a shift if you're not used to it.
I'd think things like optimizing for occupancy/memory throughput, ensuring coalesced memory accesses, tuning block sizes, using fast math alternatives, writing parallel algorithms, working with profiling tools like nsight, and things like that are fairly transferable?
