Apple’s new family 9 GPU architecture in A17 Pro and the M3 family of chips offers improved performance and power efficiency for various applications. The GPUs use Metal API to run Metal Shading Language programs, which allow for parallel execution and improved app performance. The new shader core architecture, dynamic shader core memory, and flexible on-chip memory are some of the advancements that enhance performance and efficiency. Additionally, hardware-accelerated ray tracing and mesh shading provide new opportunities for advanced rendering effects. The GPUs can execute FP16, FP32, and integer math operations in parallel, resulting in up to 2x ALU performance compared to previous Apple GPUs. Overall, these advancements benefit app developers and users by delivering faster and more immersive experiences.
