Possibly a stupid question, but does AMD lift such restrictions on models with its unified memory, by allowing the GPU to "page out" chunks of vram to system ram?

My guess is it would be much slower, because GPU processor would wait for data. Compare bandwidth - system RAM to GPU memory (PCIe): 16GBps vs GPU memory to GPU processor: 900GBps.
No idea how modeling works on AMD. (most discussions are about NVidia/CUDA)
