Santa Clara Valley (Cupertino), California, United States
Software and Services


Role Number:200178052
Apple’s GPU Software team provides the graphics software foundation across all of Apple's innovative products, including iPhone, iPad, Apple TV, Mac, and Apple Watch. Our responsibilities encompass the frameworks, developer tools, and device drivers for the GPU and Display on all Apple hardware. Metal 2 provides near-direct access to the graphics processing unit (GPU), enabling you to improve the graphics and compute potential of apps on iOS, macOS, watchOS, and tvOS. Building upon an efficient low-overhead architecture with precompiled shaders, fine-grained resource control, and multithreading support, Metal 2 further boosts performance by enabling the GPU to take more control of the rendering pipeline. Moving beyond just graphics, Metal 2's deep support for GPU-accelerated machine learning and improved developer tools make it even easier to debug, optimize, and deploy Metal apps. On Mac, Metal 2 adds support for virtual reality (VR) rendering and external GPUs and provides new APIs and optimizations to help developers adopt these new technologies within their apps.
