If you have been watching the GPU market closely, this card was expected in the Q3 2016 but it was delayed to align it better with the Virtual Reality Oculus and HTC Vive launch. This is a dual water-cooled GPU card and it is not easy to make and manufacture. This is probably a more realistic reason for the two quarter delay of the $1,499 card.
According to AMD the card is up to two times faster than the Titan X, and 1.3 times faster than Radeon R9 295X2. Liquid VR is an important part of this launch as AMD claims that this is "the world’s first platform for VR content creation and consumption."
The card is aimed at all aspects of VR content creation; including, entertainment, education, journalism, medicine and cinema, in other words it is not just a gaming card.
Radeon Pro Duo card is a dual GPU card with two Fiji GPUs where each has its own 4GB HBM 1 memory. If you combined the total available memory you will come up with 8GB of HBM on a 350W card that has three DisplayPorts and a HDMI.
The GPU's are cooled with two Cooler Master water-cooling solutions, one per GPU. These are attached to a 120 mm Nidac premium fan powered radiator. The card looks sexy with its multi-piece aluminium construction and soft touch finish modular faceplate. It comes with a LED illuminated Radeon sign and Dual BIOS Switch.
You will need a three 8-pin power connectors to run the 350W card, but since this looks like the fastest card around, it should not be a problem for enthusiast PCs with 1000+ Watt power supplies.
Here is the spec: The Radeon Pro Duo is based on two Fiji 28nm HBM powered cards. Combined these two Fiji GPUs have 8192 stream processors. It has 128 compute units (2x64 Compute Units) with a 1000 MHz engine clock. The compute performance of the card is 16.38 Teraflops and the card has total of 512 texture units, with 512 GT/s texture fill rate. It has 128 ROPs and pixel rate of 128 GP/and 512 Z/stencil.
Memory interface has a dual 4096 bit capable of addressing two times 4GB HBM at 500 MHz. the memory has up to 1024GB/s bandwidth and 1.0 Gbps speed data rate.
The card's three 8-pin power connectors provide a typical board power of 350 W. It uses PCIe 3.0.
Some 4K resolution benchmarks provided by AMD claim that you can expect around 48 FPS in Rise of the Tomb Raider from the Radeon Pro Duo. The Titan X has 38FPS. In GTA V Radeon Pro Duo scores more than 80 FPS while Titan X scores around 50. That is a huge difference.
In Battlefield 4 Titan X scores around 50 while Radeon Pro Duo scores around 80 FPS, again a significantly better. Radeon R9 295 X2 in both GTA V and Battlefield 4 scores better than Titan X and stay around 60 FPS.
Assessin's Creed Syndicate is a demanding game and at 4K Geforce Titan X scores less than 30 FPS, R9 295 X2 scores 35-ish while Radeon Pro Duo scores around 40 FPS. AMD is faster in both Far Cry Primal and Ashes of the Singularity by a significant margin.
This card should do well with Virtual Reality content. Matthew Lewis President of Practical Magic VR and Director of VR Experiences claims that the Radeon Pro Duo, "isn't just a fast video card, it's engineered from the bottom up with VR in mind” and the card targets professional VR developers and not only gamers.
