Is openGL 3.0 a chip?
OpenGL is merely an open specification for a graphics API. The software implementation and the OpenGL library is up to the vendor and different OpenGL core versions mandate different capabilities which must be supported by the underlying implementation. Examples: Geometry shaders Tesselation shaders Compute shaders For OpenGL 3.0, this is the list of core requirements: History of OpenGL Speaking of implementation, OpenGL is generally (but not always) implemented in the vendors GPU driver and its capabilities exposed to the operating system. However, it can also be implemented in software such as: llvmpipe (CPU-based) The ANGLE backend (translates OGL calls to DX) SwiftShader (CPU-based) Zink (which runs on-top Vulkan).
