It's probably one of the easiest programming languages for devs to learn and use. It's also worth noting as well that Metal is based on C++. I have a sneaking suspicion as things go multi-platform that this is one of the ways that things will get 'ported' to macOS. There is very little overhead and MoltenVK has been shown in fact to be faster than OpenGL running natively. Catalina has officially depreciated OpenCL with Catalina and it's likely that OpenCL support will officially be removed in the next major version of macOS.įinally and perhaps most importantly there is MoltenVK which is a translation layer, which maps Vulkan (which is the new common language combining relevant parts of OpenGL and OpenCL as well as being a low-level API amongst other things) to Metal. The third thing is that technically even in Catalina, macOS continues to support OpenCL v1.2, which as mentioned before hand is from 2011. The second major thing to note is that OpenCL has more or less been depreciated by Apple since 2011, when Apple stopped updating it in macOS, more or less signaling to devs to not code anything for macOS in OpenCL. Every update to OpenCL since version 1 was not directly done by Apple engineers, much like anything after v1 of Vulkan wasn't done by AMD engineers. While Apple created OpenCL, they gave the source code to Khronos group at version 1, which is similar to what AMD did with Vulkan. Click to expand.While your history of OpenCL is 'technically' true, it's not a complete picture.
