After lots of teasers it seems like now wait for the AMD’s R9 300 Series Graphics cards is coming to an end, according to latest news the R9 300 series GPUs will make their debut in the COMPUTEX TAIPEI 2015, will be started from June. Today Chinese forums leaked some pictures of AMD’s upcoming Radeon R9 390 graphics card, according to the source it is XFX Radeon R9 390. They have not revealed any information regarding to the specifications.
XFX Radeon R9 390 Double Dissipation Graphics Card Allegedly Pictured
This could either be a full or a cut down variant  of the Fiji graphics core, which will house the lead Graphics card from AMD in the Radeon R300 arrangement family. As a successor to Hawaii, Fiji will offer best execution alongside new advances, for example, HBM. It is astounding that the card demonstrated was the Radeon R9 390 (Non-X) which must be taking into account the Fiji Pro die while Radeon R9 390X will be based on the Fiji XT die. Some key subtle elements we know from past holes show 4096 stream processors and 4-8 GB of original HBM memory which conveys up to 640 GB/s memory data transfer capacity.
The card is looking great without a doubt making utilization of a hand crafted PCB which implies AMD may as of now has reference boards ready for shipment. Power connectors incorporate a 8 Pin + 6-Pin connector arrangement which call attention to a TDP of 300W however genuine utilization would be a slight bit lower. The PCB is like a Radeon R9 290X however, there are a couple of changes we can spot, particularly the missing memory modules since they have been moved on the GPU interposer and layered on top of one another.
The configuration of the  XFX double dissipation cooler has got fascinating in the most recent, forthcoming cycle. The cover makes utilization of a diamond layer configuration plan and the two 100mm fans are encompassed by a gold edge. A Radeon R9 390 mark LED-illuminated can be seen as an afterthought, in any case, I favored the bigger XFX logo on the cover which was offered on the previous cards. The fans chill the thick aluminum cluster underneath the cover.
We can estimate that the card price be set anywhere crossing the $500 US mark.
