[AMBER-Developers] difference between arch=compute_60 and arch=compute_70?

I asked this question on gitlab a week ago, but everyone is pretty busy.
I'm hoping someone in the wider audience here might know the answer:

The proposed MR ("support_ampere") to create an update for the released
version does this:

- set(SM70FLAGS -gencode arch=compute_70,code=sm_70)
+ set(SM70FLAGS -gencode arch=compute_60,code=sm_70)

SM70 covers TitanV and V100. The proposed change is in master but I'd
like to understand what is going on, and what the implications might
be. Our users are compiling now with arch=compute_70, and they would
be changing to arch=compute_60. What does this change do? Should we
expect people to have issues with the current code (that just haven't been
reported yet)? Or with the proposed change?
