I could not find any documentation about compatibility between two different cards connected by NVlink. This is from the context of using cuda.
Can we connect the same model but from different manufacturers (eg., EVGA Palit) or with different clock settings GPU or VRAM ?
Can we connect different cards within the same generation ? eg., 2080ti Titan RTX. Are there any limitation ?
Can we connect different cards with different generation ? eg., 2080ti 3090. Again, what are the contraints and limitations ? I’m thinking in particular in terms of compute calpabilities: I would expect both cards to provide their highest compute calpability, only one card can talk to the memory of the other.
Please reference official sources or actual experiments.
