but its possible in fact, nvidia are making that move with any card with asynchronous memory controller and asymmetrical memory configurations.. if nvidia can do that, i don't see a reason why AMD can't do it to keep fresh the memory pool.. bigger bus and faster bandwidth allow faster swap of textures which certainly can help, so basically is possible.. also I think not all games are so sensitive to 4GB vRAM so the work in a basis game to game can also work.. but we know slow are AMD in their driver development, don't work as good as nvidia in that aspect..
NVidia cant do it.
The drivers were updated so games end up limited to 3.5GB unless pushed very very hard, and then performance tanks.
And they have a local 0.5GB cache that is used in conjunction with system memory to give a slightly faster cache speed.
Fury has no local cache, it is solely dependent on the speed of system ram once it runs out of its 4GB.
