Metal (API)

Metal is a low-level, low-overhead hardware-accelerated graphics and compute application programming interface (API) that debuted in iOS 8. It combines functionality similar to OpenGL and OpenCL under one API. It is intended to bring to iOS some of the performance benefits of similar APIs on other platforms, such as Khronos Group's cross-platform Vulkan and Microsoft's Direct3D 12 for Windows. Since June 8, 2015, Metal is available for iOS devices using the Apple A7 or later, as well as Macs (2012 models or later) running OS X El Capitan. Metal also further improves the capabilities of GPGPU programming by introducing compute shaders.

Metal uses a new shading language based on C++11; this is implemented using Clang and LLVM.

Support for Metal on OS X was announced at WWDC 2015.

Performance

Metal should have better performance than OpenGL, for several reasons:

Metal (Wu Xing)

Metal (Chinese: 金; pinyin: jīn), the fourth phase of the Chinese philosophy of Wu Xing, is the decline of the matter, or the matter's decline stage. Metal is yin in character, its motion is inwards and its energy is contracting. It is associated with the autumn, the west, old age, the planet Venus, the color white, dry weather, and the White Tiger (Bai Hu) in Four Symbols. The archetypal metals are silver and gold.

Attributes

In Chinese Taoist thought, Metal attributes are considered to be firmness, rigidity, persistence, strength, and determination. The metal person is controlling, ambitious, forceful, and set in their ways as metal is very strong. They are self-reliant and prefer to handle their problems alone. The metal person is also wise, business-oriented, and good at organization and stability. However, the metal person can also appreciate luxury and enjoy the good things in life. Just as metal can conduct electricity, the metal person has strong impulses and generative powers and can bring about changes and transformations for those who come into contact with them. The metal person is patient, as well as a good person with a strong will.
