ReBAR may make things bit more efficient, but you still need to move data back and forth to VRAM over the slow PCIe bus.
This is not a huge problem for games, as it’s mostly sending data to VRAM that stays there for a long time, but it is a major bottleneck for many GPGPU tasks.
Since even Nvidia doesn’t seem to care about games anymore (and consoles have always used unified memory) I expect the discrete GPU to go the way of the dodo.


Even if a small ship rotates fast that would ‘t work. If you have a small diameter then there would a huge difference between the perceived ‘gravity’ at your head vs at your feet.
