XFX Radeon R9 390 Double Dissipation Allegedly Pictured – Features XDMA Crossfire, 8+6 Pin Power Configuration
The first alleged pictures of AMD's upcoming Radeon R9 390 graphics card hace been leaked. Spotted over at Chinese forums, the card which is branded as the XFX Radeon R9 390 was pictured from the front and side section and while no details were revealed, this leak could imply that launch is not too far.

There are no specifications provided by the user who posted the pictures but given the recent rumors, this could either be a full or a cut down variant of the Fiji graphics core which will house the flagship graphics card from AMD in the Radeon R300 series family. As a successor to Hawaii, Fiji will offer better performance along with new technologies such as HBM. It is surprising that the card shown was the Radeon R9 390 (Non-X) which has to be based on the Fiji Pro die while the Radeon R9 390X will be based on the Fiji XT die. Some key details we know from previous leaks indicate 4096 stream processors and 4-8 GB of first generation HBM memory which delivers up to 640 GB/s memory bandwidth to the card.
The card is quite massive since it's definitely making use of a reference designed PCB which means AMD might already have 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.
The design of the XFX double dissipation cooler has got interesting in the latest, upcoming iteration. The shroud makes use of a diamond layer design scheme and the two 100mm fans are surrounded by a gold edge. A Radeon R9 390 label which lits up (LED-backlit) can be seen on the side, however I personally preferred the larger XFX logo on the shroud which was featured on the previous cards. The fans cool off the dense aluminum array underneath the shroud.
No word on the pricing or availability were detailed but we can now expect a launch very soon. Price could be set anywhere crossing the $500 US mark. Since details are limited to just looks of the card, we can't really make up anything else aside from the rumored specifications mentioned in the chart below. You can also see the difference between XFX's double dissipation coolers which were introduced on the Radeon R200 series and now being modified for the Radeon R300 series.
