During AMD’s presentation yesterday they mentioned a dual Fiji card, although they didn’t show it. Later that night they showed it at a presentation at the PC Gaming Show and I do have to say it is quite impressive!
The prototype board of the card was shown and I do have to say wow. The fact that AMD is able to fit two extremely powerful GPUs so close together on a PCB is extremely impressive. The prototype board also only has two 8pin PCI-Express connectors, which is the same as the single-GPU Fury X card. This means that the card will not need more than 375W of power.
We are to assume that this card is based off of two Fiji XT chips so that would give it 8192 Stream Cores, 512 TMUs, 128 ROPs, 8GB of HBM1 memory running across the 8192-bit memory bus. This will give the card a memory bandwidth of 1024 GB/s.
The two Fiji XT chips communicate to each other by the PLX chipset, which you can see between the two.
Based on previous naming we can assume AMD will be calling this card the AMD Radeon R9 Fury X2, but the naming has not been confirmed. The card is expected in Autumn of this year.
