Metal

Apple’s low-overhead graphics and compute API designed to maximize hardware performance on Apple silicon.

Metal gives developers direct, near-to-the-metal access to the GPU on iOS, macOS, and visionOS. By eliminating CPU bottlenecks and streamlining command submission, it allows applications to render complex 3D scenes and execute massive parallel compute workloads with minimal overhead. The framework integrates a unified shading language (based on C++14 and C++17) with a suite of profiling tools in Xcode: giving developers the precise control needed to squeeze maximum throughput from Apple silicon.
