Apple M1 Ultra: All you need to know about this powerful chip

Disruptive Ultrafusion Technology

Apple has finally unveiled the much-awaited M1 Ultra. The new chipset surpasses the already powerful M1, M1 Pro and M1 Max chips. In addition, it delivers industry-leading performance per watt. Apple announced its latest silicon chips alongside the iPhone SE 2022, the new iPad Air 5, Mac Studio, and Studio Display.

The M1 Ultra sets the benchmark with 128GB of unified memory, 20-core CPU, 64-core GPU and 32-core Neural Engine. The combination provides unparalleled exposure for developers, 3D artists and other professionals. Let’s take a look at what the M1 Ultra has to offer.

UltraFusion involves connecting two M1 Mac dies. In other words, the M1 Ultra is made by slapping two M1 Maxes together. This has helped propel the M1 Ultra to an unprecedented level.

Generally, such arrangement is not preferred by chipmakers. Connecting chips increases latency, reduces bandwidth and consumes more power. Apple has overcome this limitation by using a silicon interposer that routes connections from one socket to another.

The innovative technology helps achieve 2.5TB/s low latency and 4x interprocessor bandwidth. Thanks to the arrangement, macOS treats the M1 Ultra as a single chip. All profit without any loss.

M1 Ultra CPU Performance

The M1 Ultra performance level differs from the chart. Apple claims that the M1 Ultra delivers 8x performance as compared to the M1 Ultra. You get 20 CPU cores, 16 of which are high-performance cores.

Apple claims the M1 Ultra crushes the fastest available 16-core PC desktops with 90 percent more multi-threaded performance. The best part is that the M1 Ultra achieves peak performance at 100W low power. Very impressive, isn’t it?

The M1 Ultra has a 64 core GPU that uses 200 watts less power at maximum output. Apple has enhanced the integrated memory architecture.

The result is 800GB/s memory bandwidth with up to 128GB of RAM. Unified memory is a specific architecture in which the entire system uses a single RAM. Typically, different parts of the system use different RAM pools.

The Magic of the 32-Core Neural Engine

A neural engine is hardware that can process billions of operations every second. It enables features like Face ID and other machine learning requirements. Apple designates Neural Networks and Machine Learning for Neural Engine instead of Silicon CPU/GPU.

With the M1 Ultra, you can expect faster ProRes video encoding. The Mac Studio 18 powered by the M1 Ultra claims to support 8K ProRes playback streams. Other highlights include the Thunderbolt 4 controller, Secure Enclave, and runtime anti-exploit technology.

macOS apps support

macOS app developers are rapidly transitioning to universal apps. macOS Monterey is designed to accommodate exponential growth in memory bandwidth, CPU and GPU. Developers can now take advantage of the M1 Ultra’s processing prowess. Meanwhile, the iPhone and iPad apps will be available on the Mac.


The Apple M1 Ultra will debut with the Mac Studio, a performance-oriented machine built for professionals. In all likelihood, the new chipset will soon be available on all MacBooks and iMacs in the coming months. Apple has already moved to the M1 for its MacBook lineup.

durable and eco-friendly

Apple is known for its use of durable materials. The M1 Ultra consumes 1000 kWh less than the high-end PC. It saves on electricity bills and contributes to a greener environment.

Additionally, Apple aims to become carbon neutral by 2030. In other words, all Apple chips will be 100 percent carbon neutral.

The M1 Ultra is on par with one of the most powerful GPUs commercially available. It is said to offer 2.5x performance unlike the range-topping Intel Core i9 desktop. Needless to say, Intel has a lot to do.
