ROCm supports AMD GPUs like the RX 460 for OpenCL development. The document provides steps to install ROCm on Ubuntu 16.04 including downloading ROCm packages, installing the ROCm DKMS driver, and adding the user to the video group. Basic OpenCL code is then compiled and run successfully on the RX 460 showing ROCm with an AMD discrete GPU works.
