Read it well, an announcement, don't expect any reviews. We do have some photo's and some perf numbers though. The Dual Fiji GPU based AMD Radeon Pro Duo has been announced. Imagine two Fury X cards and well, there you go! 

The design is more or less the same albeit it has a longer PCB with the two GPUs tied towards a thick 120mm liquid cooling solution. The AMD Radeon Pro Duo is announced alongside the GDC Liquid VR announcements. The product will offer 16 teraflops of performance, indicating two fully enabled Fiji XT GPUs. If you look at the photos you're going to notice three 8-pin power connectors and thus could use up-to 525 Watt. We do expect some refined tuning in power consumtion though, say 2x 200 Watt. The card's display output configuration four DisplayPort 1.2 connectors.

AMD Radeon Pro Duo dual-GPU Fiji was developed under code-name Gemini would have 8 GB HBM1 graphics memory with a whopping 8192 stream processors. The earlier photos however indicated two 8-pin PCI Express power connectors, this now is three. The specs below are not final yet based up-on assumptions (they should be pretty conclusive though). The AMD Radeon Pro Duo is planned for availability in early Q2 2016 at an anticipated SEP of $1499 USD.
 

One Radeon Fury X pushes close to 8.6 TFLOPS of performance, the  dual-GPU version offers over 16 TFLOPs of single precision performance. And yes a dual-GPU Fiji would have 8 GB HBM1 graphics memory with 8192 stream processors. 

Some quick numbers (testing conducted by AMD Performance Labs as of March 7, 2016). The AMD Radeon Pro Duo, AMD Radeon R9 295X2 and Nvidia’s Titan Z, all dual GPU cards, on a test system comprising Intel i7 5960X CPU, 16GB memory, Nvidia driver 361.91, AMD driver 15.301 and Windows 10 using 3DMark Fire Strike benchmark test to simulate GPU performance.

PC Manufacturers may vary configurations, yielding different results. At 1080p, 1440p, and 2160P, AMD Radeon R9 295X2 scored 16717, 9250, and 5121, respectively; Titan Z scored 14945, 7740, and 4099, respectively; and AMD Radeon Pro Duo scored 20150, 11466, and 6211, respectively, outperforming both AMD Radeon R9 295X2 and Titan Z.

Let me clearly stipulate that the Titan Z is still kepler based as there is no dual-GPU Maxwell based product released.

AMD (NASDAQ: AMD) today introduced the world's most powerful platform for virtual reality (VR) , capable of both creating and consuming VR content. AMD's Radeon™ Pro Duo with its LiquidVR SDK is a platform aimed at most all aspects of VR content creation: from entertainment to education, journalism, medicine and cinema. With an astonishing 16 teraflops of compute performance, AMD offers a complete degree solution aimed at all aspects of the VR developer lifestyle: developing content more rapidly for tomorrow's killer VR experiences while at work, and playing the latest DirectX 12 experiences at maximum fidelity while off work.

AMD continues to solve major problems developers face by reducing latency and accelerating the VR pipeline through close collaboration with the content development community and with AMD LiquidVR technology. AMD's next step in advancing VR is with the new AMD Radeon Pro Duo, an incredibly advanced and powerful dual-GPU board that delivers the horsepower needed by VR designers, content creators, and for VR content consumers.
"More powerful computing platforms are rapidly leading to greater immersive experiences, said Raja Koduri, senior vice president and chief architect, Radeon Technologies Group, AMD. "This is most evident with VR which demands ever higher compute performance with rock solid consistency. Our new AMD Radeon Pro Duo with our LiquidVR SDK is the world's fastest platform for both content creation and consumption1, enabling a world class graphics and VR experience."

AMD Radeon Pro Duo is the initial product of the AMD VR Ready Creator line. The AMD Radeon Pro Duo with the LiquidVR SDK is also the platform of choice for Crytek's VR First initiative for nurturing new talent in the field of virtual reality development by powering virtual reality labs in colleges and universities worldwide.

"As a state of the art platform, the AMD Radeon Pro Duo with the LiquidVR SDK is the perfect choice as the graphics standard for Crytek's VR First initiative," said Cevat Yerli, CEO, Crytek. "As a graphics card that bridges the needs of both VR content creators and content consumers, it's extremely fitting hardware to supply to the brightest up-and-coming developers, who will surely shape the future of virtual reality and immersive computing."
