The M1 Ultra is the most powerful Apple chip to date and is used in the Mac Studio.

Everything you need to know about the Ultra is covered in this guide.

M1 Ultra Detailed

The Ultra is Apple's fourth system on a chip, and it puts the company one step closer to ending the use of Intel chips in Macs.

It is a new feat of engineering from Apple that makes the ‌M1‌ Ultra special. The M1 Max and Ultra chips are connected together through an Apple-developed method, so they offer double the performance of the.

Ultra is a system on a chip that integrates several different components.

Traditional Intel-based Macs used multiple chips for the processor, graphics, I/O, and security, but integrating multiple components onto one chip allows Apple Silicon chips to operate faster and more efficiently than Intel chips.

114 billion transistors are the most ever in a personal computer chip, and it is the largest Apple chip to date.

M1 Max + M1 Max

Apple has given the name UltraFusion to its packaging architecture. The dies of two chips are connected to create a single system on a single chip.

It is possible to scale performance by connecting two chips on a board, but that comes with tradeoffs like increased latency, reduced bandwidth, and more power consumption.

Apple is using a Silicon interposer that is designed to connect the two chips across more than 10,000 signals, offering 2.5 terabytes of low-latency inter-processor bandwidth. Developers don't have to take any steps to take advantage of the full capabilities of the ‌M1Ȁ Ultra because it behaves as a single chip.

M1 Ultra vs. Intel Chips

The A-series chips that have been used in the iPad and iPhone have an Arm-based architecture.

Apple has decided to move away from the x86 architecture that Intel is built on. Taiwan Semiconductor Manufacturing Company (TSMC) builds all of Apple's A-series and M-series chips.

CPU and GPU

The M1 Ultra has a 20-core chip that has 16 high performance cores and four high efficiency cores, which is equivalent to two 10-core chips.

The Neural Engine is capable of running 22 trillion operations per second.

The Ultra is faster and more powerful than any other chip that Apple offers. The best graphics card Apple has used to date is not the best performing graphics card.

Apple says that the Ultra can offer 90 percent higher performance than the fastest 16-core PC CPU within the same power envelope. It offers the same performance as one of the most popular graphics cards while using 1/3 as much power, and it uses 200W less power.

Memory

Apple uses a unified memory architecture that lets the processor components use the same data pool rather than having to swap between different pools of memory. It is a technique that makes the M-series chips very efficient.

The Ultra supports up to 128GB of unified memory. The memory bandwidth is 2x more than the M1 Max.

The Media Engine in the Ultra is designed to accelerate video processing without impacting battery life. The Ultra has double the media engine capabilities of the M1 and has more video decode throughput.

It can play back up to 18 streams of 8K video, double the capabilities of the M1 Max.

Other Chip Features

The Ultra has several built-in technologies.

  • 32-core Neural Engine for machine learning.
  • A display engine that drives external displays.
  • Integrated Thunderbolt 4 controllers that offer more I/O bandwidth than before.
  • A custom image signal processor used to enhance the camera's image quality.
  • Secure Enclave with hardware-verified secure boot and runtime anti-exploitation technology.

Macs With an M1 Ultra Chip

The high-end Mac Studio is only available with the ‌M1 Max‌ chip.

M1 Ultra Security Features

With the M-series chips, the security and other features on the Macs are built right in, unlike the built-in T2 chip on the Intel Macs.

The Ultra has a built-in secure enclave that manages Touch ID and a storage controller with a AES encryption hardware for faster and more secure performance.

Running Apps on the M1 Ultra

The M-series chips use different architecture than Intel chips, so Apple has designed tools that allow developers to create Universal app binaries that run on both Apple Silicon and Intel chips, plus there is a translation layer that lets x86 apps operate on machines with Apple Silicon.

The apps designed for Intel machines will continue to run on Macs with limited performance compromises. The performance enhancements added by the M1 Pro and M1 Max chips make the apps run the same on both Apple and Intel.

Almost all popular Mac apps will be built to run on the Macs over the course of a few years, and everything should function as normal.

There is one significant compromise when choosing an Apple Macintosh, and that is Windows support.

There is no Boot Camp for Macs with Apple chips, and the machines are not officially able to run Windows, although some users are figuring out ways to make it work. Microsoft licensing its Arm-based version of Windows to consumers is the only thing that could bring official support in the future.

If app developers make them available, Ultra Macs can run apps for the iPad, as well as Mac apps.
