Computer technology site WCCFTech has published what it claims to be the first teaser image of the graphics card likely to be known as the AMD Radeon R9 390X. It is the same Fiji XT powered flagship Radeon that AMD teased at GDC, says the site.

Looking at the picture above you can see that the card is rather short in length. This is because the pictured example is a water cooled card with what appears to be a 120mm radiator in its construction. TechPowerUp says that this is one of a pair of Radeon R9 390X graphics card SKUs that will be produced, the other will be air cooled and just a little shorter than the R9 290X. Concerning the shorter card, as teased in the picture, TPU explains that AMD's HBM implementation with 8GB of RAM on the GPU package facilitates a compact card with the heatsink covering everything. AMD promised such compact form factor cards during its recent Financial Analyst Day.

Key specifications of the AMD Radeon R9 390X are expected to be as follows:

  • 4,096 GCN 1.2 stream processors
  • GPU clock speed of 1.05GHz
  • 256 TMUs
  • 128 ROPs
  • 8GB of HBM
  • 4096-bit wide HBM interface
  • 1.25 GHz memory clock
  • memory bandwidth of 640GB/s
  • compute performance of 8.5TFLOPs

The AMD reference card as pictured at the top of the page includes three DisplayPort 1.2a and one HDMI 2.0a connectors. Adding to their report WCCF Tech has another shot, below, which is purported to show a closeup of the Fiji XT chip and HBM interposer on the graphics card.

The official launch of the AMD R 300 series graphics cards will be at E3 and/or Computex this summer.

Exciting! Not that I'll be buying one. My R9 280x is more than adequate unless something spectacular happens in the gaming world pretty sharpish.. Though I will admit, my GPU is hugely bottlenecked by my Phenom II 955 (standard clock) but unless someone is feeling generous, an upgrade is not in the pipeline until AM4 is released.

Having said this, my rig still manages Skyrim with a bucket full of mods and ENB acceptably as well as playing games such as Crisis II and Ghosts (sorry guys) at maximum settings.
There doesn't appear to be a fan on the GPU body itself. Does that mean the VRM is cooled via the AIO?

Either way, very interesting. Hope it comes out very soon.
I dunno, there's just something nice about having a physically large GPU, from the unboxing to the fitting.
If they start getting smaller I'll shed a little tear.

Isn't the HBM memory basically on the GPU package? As such its cooled by the same heat sink as the gpu and doesn't need a fan on the body.

Although if you take the R9 295X2 for reference the fan on that card is for a little bit of VRAM cooling but mostly for the VRM's benefits. I would have thought that for safety they would still require some active cooling over the VRM's of the 390X.

Yeah, the VRAM is on package now. Put I was referring to the Voltage Regulator Modules (VRM). I agree, they got very hot on the 290X. Some of the aftermarket watercooling with AIO kits really struggled to cool them. Perhaps the waterblock has been designed to cool them to ?

Guess we'll find out eventually.
