During the PC Gaming Show, which ran for a mammoth two and a half hours at E3 2015 last night, AMD CEO Lisa Su briefly appeared on stage to show off another Radeon graphics card that the company only briefly mentioned during the launch of their Fury line earlier in the day.

The card shown was a dual-GPU Fiji-based card (seen above thanks to PC Gamer), which currently doesn't have a name, or any associated specifications. From the layout of the card you can clearly see four stacks of high-bandwidth memory (HBM) flanking each GPU, as well as two 8-pin PCIe power connectors: curiously the same power delivery system as the single-GPU Radeon R9 Fury.

This dual-GPU card also comes with three DisplayPorts and one HDMI port, judging by the connectors on the left-hand side. The PCB for the card is also fairly short for a dual-GPU card, which is down to the space-saving HBM that also allowed AMD to develop the Radeon R9 Nano.

Also missing at this stage is a cooler that's capable of dissipating heat from two Fiji GPUs, although it's expected that this dual-GPU card will use a modified version of the liquid-cooling solution used on the dual-GPU Radeon R9 295X2.

As the dual-GPU Fiji card shown by AMD was clearly not ready for release, Su didn't mention anything about a release date or a price tag, aside from a vague statement that the card would be available this fall.
