Phoronix published a review on the NVIDIA GeForce GTX 1070 On Linux: Testing With OpenGL, OpenCL, CUDA & Vulkan A quote from the article:

If you were amazed by the GeForce GTX 1080 performance under Linux but its ~$699 USD price-tag is too much to handle, the GeForce GTX 1070 is now shipping for $399~449 USD. NVIDIA sent over a GeForce GTX 1070 and I've been putting it through its paces under Linux with a variety of OpenGL, OpenCL, and Vulkan benchmarks along with CUDA and deep learning benchmarks. Here's the first look at the GeForce GTX 1070 performance under Ubuntu Linux.
