> Is it theoretically possible with PC motherboards and GPUs that sit in card slots of some form? As far as I'm aware, not with the speed that unified memory gets. The trace and path lengths alone put hard caps on what can be done in terms of signalling speed. But I'm not an expert, I'm recounting what I was told when I asked the same question! Perhaps the state of the art has improved in this space?
