AMD Fiji XT Reference PCB as Short as GTX 970 Reference, R9 295X2 Performance
AMD's upcoming Radeon R9 390X graphics cards will ship in two SKUs - an air-cooled one, with a moderately long reference design board (though not as long as the R9 290X), and a new Water-Cooled Edition (WCE) SKU, which will feature a very compact PCB - one that could be no bigger than that of the GeForce GTX 970 reference. This is possible because of AMD's HBM implementation. The 8 GB of memory on this card is present on the GPU package, as bare 3D-stacked DRAM dies, surrounding the GPU die, with an IHS covering everything; rather than the GPU package being surrounded by memory chips. Below is a mock-up of the card by ChipHell. It's not a picture. The radiator is off-proportions, the Radeon logo is misaligned, and the PCIe I/O is misaligned, etc. It should still give you a good idea of what the card looks like, particularly its length. Other specs on hand so far, include 4,096 GCN 1.2 stream processors, 256 TMUs, 128 ROPs, and a 4096-bit wide HBM interface, which at 1.25 GHz memory clock, will offer memory bandwidth of 640 GB/s.
While Fiji package will be bigger than that of, say, "Hawaii," overall the setup is more space-efficient, and conserves PCB real-estate. The PCB hence only has the GPU package and the VRM. AMD is doing away with the DVI connector on its reference PCB. It will only feature three DisplayPort 1.2a and one HDMI 2.0a. The WCE variant will feature a pump+block covering the GPU package, which will come factory-fitted to a 120 x 120 mm radiator. The air-cooled R9 390X will be longer, but only to house a heatsink and lateral blower. The single-GPU card could offer performance comparable to the dual-GPU R9 295X2, which is faster than the GeForce GTX TITAN-X. AMD CEO Lisa Su, speaking at the Investor Day event, in New York, on 6th May, hinted that the product could launch on the sidelines of either Computex 2015 (early-June) or E3 (mid-June).

It'll be weird though (with HBM) having memory on chip and smaller cards with more power.
No more behemoths. Almost a sad day for open cases!
Truckloads of salt.
edit: I removed the racist word he was using from his quote in my post.
Although you cite them that is illegal so I suggest you place the original image on you article immediately as I am ready to take this one step further
The fact this site took an image and doctored it is discusting.
Using an image is one thing, and legal. Doctoring other peoples property is no and is illegal.
WCCftech are the most honest site around who sound out rumours when they are.
They do not hold favouritism either which is why they got the image in the first place.

You need to understand that
using images is one thing if cited. Doctoring it is illegal without authorisation.
If the image was given by AMD, WCCFTECH should cite AMD as source. If not, its not a legal image in the first place.
Best part is, I don't care. And please follow TPU forum rules and stop double/triple posting.
