Nema tu nikakvog gimpanja sa VRAM na fiji-ju Tonči je to objasni a i ljudi na OCN na koji način AMD koristi HBM na fiji-ju
"That's in relation to the use of the framebuffer and dynamic memory pools by AMD. It's what I was describing in a prior thread, when I believe it was Serandur whom with I had a mis-understanding (we cleared that misunderstanding), about how AMD uses the 4GB of HBM memory on Fiji. AMD use it as a cache, whereas all of the important data needed to render a given amount of frames is kept in the framebuffer (HBM) and all of the non-pertinent data is kept in system memory (dynamic memory). The PCIe bus is used to transfer/swap data between the two pools. AMD hired two engineers to optimize their DX11 software driver for this task. For DX12, the developers have that responsibility.
This slide explains how 4GB of memory is enough for 4K under DX12"
