![]() ![]() But with the new Apple family 9 GPUs, we are increasing performance to unprecedented levels thanks to several new exciting advancements.įirst is a brand new shader core architecture that improves the performance and power efficiency of your existing apps, which, right away, benefits the experience you deliver while also meeting the demanding challenges of the next-generation of apps that you will build. And to scale performance even further, a GPU will have many shader cores that can also run in parallel, giving an app tens of thousands of parallel threads of execution.Īlready, the GPUs in today's existing iPhones, iPads, and Macs, have incredible performance.Īs well as a powerful suite of developer tools to allow app developers to maximize the GPU's potential. Each shader core can run thousands of threads in parallel. ![]() It is the GPU, ultimately, which is responsible for executing these shaders in parallel.Īt the heart of every GPU are its shader cores. ![]() This parallelism is achieved by running Metal shader programs many times over in parallel on different inputs such as each vertex in a 3D rendered scene or each pixel of the screen. What all these shaders share in common is massive data parallelism, which is the opportunity to greatly improve the performance of an app by running it in parallel. These shader programs can range from small, simple shaders that execute just a handful of lines of code to large complex shaders that spend hundreds of thousands of lines of code, frameworks, and libraries. The Metal API is used to harness the computing capabilities of Apple's GPUs, and collectively, these apps run a diverse set of Metal Shading Language programs. Whether it be gaming on the go with the new iPhone 15 Pro, delivering silky smooth UI animations for your apps on the new iMac, or leveraging machine learning to perform advanced video and image processing on the new MacBook Pros, the GPU plays a critical role in enabling these apps. I'm excited to tell you about the new Apple family 9 GPU architecture in A17 Pro and the M3 family of chips, which are at the heart of iPhone 15 Pro and the new Macs.Īcross Apple's product line, the GPU powers many of the rich user experiences our customers love. Welcome, my name is Jedd Haberstro, and I'm an Engineer in Apple's GPU, Graphics, and Displays Software Group. ![]()
