The rumour mill is going into overdrive with the possible release of AMD’s new flagship GPU. The Radeon R9 380X is rumoured to have 4096 cores and 4GB of the next-gen HBM (High bandwidth memory). This card has been codenamed Fiji XT and is set to replace the current high-end R9 290X. It will be interesting to see just how much of a difference, if any the change in architecture and new, super fast HBM RAM makes on this card. It has a theoretical computational power rate that is approximately 45% over the 290X.
Other source reveal that this card is the first in the world with stacked memories (2.5D interposer stacking), where the memory chips are placed at the side of the graphics processor on the same substrate. The idea behind this is to streamline communication between both parts and provide both a higher efficiency and a significantly higher bandwidth when compared to GDDR5.
Another interesting detail (if true) is that the card will have a closed water cooling system much like the R9 295X2 has.
We can’t wait to get our hands on this! Stay tuned for more details as they arise.
