I run 2 instances per card on each of my Radeon VIIs for 2 reasons:

1. Gives an total throughput boost in the 7-10% range;

2. If one job hangs or crashes - infrequent, but it does happen - one minimizes the total throughput hit.

Even if one has a GPU model where 2-instances is slightly slower in total-throughput terms - say no more that 5% - [2] makes it worth doing, IMO.

On the R7 I found negative benefit from > 2 instances.
