16-Way OpenCL Compute Comparison Of The Latest Polaris & Pascal GPUs

With JuliaGPU and MandelbulbGPU, the current AMDGPU-PRO OpenCL driver stack failed to run. The NVIDIA results are shown for reference.

Here's a look at the AC system power consumption monitoring throughout all of the OpenCL compute benchmarks completed.

Well, these OpenCL Linux compute tests were certainly interesting to say the least. With the AMDGPU-PRO driver stack, the OpenCL performance with the RX 480 and R9 Fury was much more competitive than we found under the OpenGL (and Vulkan) graphics testing with either AMDGPU-PRO or the RadeonSI Gallium3D driver. In a number of these OpenCL tests (particularly LuxMark), the AMD OpenCL Linux performance showing was very strong when using this closed-source CL implementation. However, in other OpenCL workloads the AMDGPU-PRO performance wasn't as good and in some cases the tests didn't even run on AMDGPU-PRO.

The NVIDIA Linux OpenCL results were pretty much as expected for their proprietary driver except for the GTX 1080 performance oddity affecting LuxMark.
