However the company is also pushing the use of Physically Based Rendering (PBR), a compute-intensive rendering solution that uses far more accurate rendering algorithms to accurately model the physical characteristic of a material, in essence properly capturing how light will interact with that material and reflect off of it rather than using a rough approximation.

However as FP64 compute is not widely used in graphics, this is not something NVIDIA believes will be an issue.

Bald Eagle products “incorporate HSA features, enabling applications to distribute workloads to run on the best compute element—e.g., CPU, GPU, or a specialized accelerator such as video decode—for up to 44 percent more 3D graphics performance and up to 46 percent more compute performance than comparable Intel Haswell Core-i CPUs,” said the company.

Heterogeneous System Architecture (HSA): The 2nd generation AMD Embedded R-series APU is the first embedded processor to incorporate HSA features, enabling applications to distribute workloads to run on the best compute element — e.g., CPU, GPU or a specialized accelerator such as video decode — for up to 44 percent more 3-D graphics performance and up to 46 percent more compute performance than comparable Intel Haswell Core-i CPUs.

Now that it is out, multiple sources are claiming the vendor-supplied benchmarks are exaggerated or simply untrue.

Ironically, the launch of the Radeon R9 295 X2 video card might have lessened that number of benchmarks available for NVIDIA's driver, who knows?

The HIS R7-240 iCooler will round out the list with 1GB of GDDR5.

It appears that the HIS R9-280X iPower IceQ X2 will be at the top of the list and will sport 3GB of GDDR5 Memory.
