We rely on you, the community, to help maintain this list of OpenCL implementations and the short descriptions used alongside each implementation are from the vendors own sites.  If you have any updates please share them with us via our General Enquiry form.

The Khronos Group maintains a list of the products that have passed OpenCL Conformance testing at: https://www.khronos.org/conformance/adopters/conformant-products/opencl
