Accelerate graphics and much more

Whether you want to build a graphics-intensive app, a cutting-edge game with beautiful visuals, or target demanding compute workloads like machine learning, Metal puts the advanced capabilities of Apple-designed GPUs at your fingertips. Tap into the incredible performance and efficiency of Apple silicon across iPhone, iPad, Mac, Apple TV, and Apple Vision Pro.

About Metal

Metal is a modern, tightly integrated graphics and compute API coupled with a powerful shading language that is designed and optimized for Apple platforms. Its low-overhead model gives you direct control over each task the GPU performs, enabling you to maximize the efficiency of your graphics and compute software. Metal also includes an unparalleled suite of GPU profiling and debugging tools to help you improve performance and graphics quality.

What’s new

Unified shaders and device initialization

Now you can build your Metal libraries once and deploy across Mac, iPad, and iPhone without having to recompile, saving you valuable iteration time. Metal device initialization has also been simplified, enabling you to target these platforms with the same code.


Game Porting Toolkit 2

Accelerate your timeline, whether you’re bringing an existing game or one that’s currently in development. With the Game Porting Toolkit 2, it’s never been easier to bring advanced games to Mac, iPad, and iPhone — and to deliver great experiences for players.

Now, when you use Metal shader converter to convert your shaders, you can take advantage of Xcode shader debugging tools that now support debugging your original source code. You can also use the GPU binary compiler to build all shader stages, including Mesh shaders, which makes it compatible with all shaders converted through Metal shader converter.

Port advanced games to Apple platforms

Residency sets

Make Apple silicon’s unified memory accessible to the GPU faster than ever with the new Metal Residency Set API. Group related resources into sets and make them resident together.

Ray tracing improvements

Apple silicon supports hardware accelerated ray tracing. New Metal ray tracing support for direct state access unlocks more performance by avoiding extra copies of intersection results. You can also take advantage of row-major matrix layouts when porting shaders.

Metal shading language enhancements

Metal offers you a powerful shading language to take advantage of Apple GPUs. This year, you can take advantage of new global resource bindings to declare your buffers, textures, and samplers at a global scope and use them anywhere in your shaders. You also have more control over memory coherency including support for device coherent operations for cooperative threadgroup algorithms as well as support for os_log to print to the console from within your shaders.

Machine learning

Transformer models with MPS Graph

Integrate machine learning transformer models into your Metal pipelines with new features to improve compute, bandwidth, and quality. Then, visualize your serialized MPSGraph packages using the new MPSGraph Viewer, which lets you analyze opportunities to optimize your networks.

Accelerate machine learning with Metal

ML frameworks

Accelerate the training of machine learning models right on your Mac with TensorFlow, PyTorch, and JAX. With improvements to the Metal backend, you can train the’s top 50 networks and seamlessly deploy PyTorch models with custom Metal operations using new GPU-acceleration for Meta’s ExecuTorch framework. You can also take advantage of mixed precision training using JAX.
