Apple unveiled the M1 Ultra, the company’s next big leap forward in terms of silicon and the Mac. Thanks to UltraFusion, Apple’s innovative packaging architecture that interconnects the die of two M1 Max chips to create a system on a chip (SoC) with unprecedented levels of performance and capabilities, M1 Ultra provides breathtaking computing power to the new Mac Studio while maintaining industry-leading performance per watt. The new SoC has 114 billion transistors, which is the most number ever seen on a personal computer device. The M1 Ultra can be configured with up to 128GB of high-bandwidth, low-latency unified memory that the 20-core CPU, 64-core GPU, and 32-core Neural Engine can access, delivering incredible performance for developers compiling code, artists working in massive 3D environments that were previously impossible to render, and more.
Apple’s M1 Ultra is another game-changer that will once again stun the PC market. We’re able to expand Apple silicon to unprecedented new heights by linking two M1 Max die with our UltraFusion packaging design,” said Johny Srouji, Apple’s senior vice president of Hardware Technologies. “The M1 Ultra completes the M1 series as the world’s most powerful and capable SoC for a personal computer, with its powerful CPU, large GPU, amazing Neural Engine, ProRes hardware acceleration, and a massive amount of unified memory.”
UltraFusion Architecture is a ground-breaking design.
The M1 Ultra is built on top of the incredibly powerful and energy-efficient M1, Max. The die of two M1 Max is linked using UltraFusion, Apple’s custom-built packaging architecture, to create M1 Ultra. Connecting two CPUs through a motherboard is the most popular technique to scale performance, although this often comes with substantial trade-offs, such as higher latency, lower bandwidth, and increased power consumption. Apple’s UltraFusion, on the other hand, employs a silicon interposer to connect the chips over more than 10,000 signals, resulting in a whopping 2.5TB/s of low-latency inter-processor bandwidth – more than four times that of the top multi-chip interconnect technology. This allows the M1 Ultra to function and be recognised by software as a single chip, removing the need for developers to modify code to make use of the M1 Ultra.
M1 Ultra Support for macOS and Apps
The Mac experience has always been about the deep synergy between hardware and software. macOS Monterey was built with Apple silicon in mind, making use of the M1 Ultra’s massive boosts in CPU, GPU, and memory bandwidth. Apps can take full use of the new processor thanks to developer tools like Metal, while Core ML optimizations take advantage of the new 32-core Neural Engine, allowing machine learning models to run faster than before.
Users may download the most programmes for Mac ever, including iPhone and iPad apps that can now run on Mac and Universal apps that unleash the full capability of the M1 family of CPUs. Apps that haven’t been upgraded to Universal will continue to work.
Another Step Forward in the Apple Silicon Transition
Apple has put Apple silicon in practically every Mac in its current range, and each additional chip — the M1, M1 Pro, M1 Max, and now the M1 Ultra — gives the Mac incredible new capabilities. The M1 Ultra is the final member of Apple’s M1 series of processors, and it powers the all-new Mac Studio, a high-performance desktop machine with a reinvented compact design made possible by Apple silicon’s industry-leading performance per watt.
The Environment and Apple Silicon
Apple’s proprietary silicon’s energy efficiency allows Mac Studio to consume less power during its lifespan. In fact, over the course of a year, Mac Studio uses up to 1,000 kilowatt-hours less energy than a high-end PC desktop while offering exceptional performance. 5
Apple is now carbon neutral in its worldwide operations, and by 2030, the company expects to have a net-zero climate impact throughout the whole organisation, including manufacturing supply chains and all product life cycles. This means that every chip Apple makes will be carbon neutral from design to production.
