WCCF Tech got its hands on a pair of photos of what is claimed to be the XFX Radeon R9 390 Double Dissipation graphics card! The images originated somewhere on a Chinese forum but no specifications were provided. The card is believed to feature the Fiji Pro GPU with probably 4GB of HBM memory, it features a custom PCB and a cooling solution with two 100mm fans.
The card is quite massive since it’s definitely making use of a custom designed PCB which means AMD might already has reference boards ready for shipment. Power connectors include an 8 Pin + 6-Pin connector configuration which point out to a TDP of 300W though actual consumption would be a tad bit lower. AMD is once again making use of their XDMA Crossfire technology which has done really good to them in multi-GPU scaling. Display outputs include DVI, HDMI and a mix of display ports though we can’t really confirm since the I/O bracket was not shown. The PCB is similar to a Radeon R9 290X however there are a few changes we can spot, especially the missing memory modules since they have been relocated on the GPU interposer and layered on top of each other.
