AMD FirePro S9300 X2 is a Radeon Pro Duo for the HPC set
 

AMD's Radeon Pro Duo combines a pair of Fiji GPUs for 16 TFLOPS of workstation-class computing power on the desktop. Today, the red team is taking similar power to the data center with its FirePro S9300 X2. This card combines two fully-enabled Fiji packages, each with 4GB of non-ECC HBM RAM, in a server-friendly form factor. Each GPU runs at 850 MHz. That's good for 13.9 TFLOPS of theoretical FP32 compute performance in a 300W power envelope, according to AnandTech.

As high-performance computing cards go, the S9300 X2 is targeted at applications that need the highest-possible single-precision (or FP32) performance available. FP32 performance is apparently especially important to modeling applications in the oil-and-gas industry. In a wave-equation modeling performance demonstration, AMD ...
