Speed runs in the family.
Apple silicon has transformed our Mac lineup, bringing unbelievable performance and power efficiency with its breakthrough system on a chip (SoC) architecture. Combining the CPU, GPU, I/O, Neural Engine, and more into a single SoC with unified memory, this architecture means all Mac computers are way faster, cooler, and more power efficient. To complete the M1 family, we took another giant leap with Apple Silicon to bring even more extreme levels of performance for the desktop. The challenge is that there are physical limits to creating a larger die than M1 Max. Enter UltraFusion.
Joining forces.
The incredible M1 Ultra chip actually starts with M1 Max. From its inception, M1 Max has held the ability to connect to another M1 Max die using a custom-built packaging architecture called UltraFusion. With twice the connection density of any technology available, UltraFusion provides a massive 2.5TB/s of low-latency interprocessor bandwidth between the two dies using very little power.
The final member of the M1 family, M1 Ultra joins two M1 Max dies — yet it looks like a single piece of silicon to software, so apps benefit from its extraordinary capabilities without requiring any additional work from developers. The result is the most powerful chip ever in a personal computer.

At the core of it all. M1 Max and M1 Ultra CPUs leverage high-performance cores and high-efficiency cores — up to 20 CPU cores total — to deliver industry-leading performance per watt. Up to 64 GPU cores deliver massive amounts of graphics performance. And up to 32 Neural Engine cores execute up to 22 trillion operations per second for accelerated machine learning tasks.

Mind-blowing performance meets cutting-edge power efficiency. It’s a lot to process.
In both CPU and GPU processing power and performance per watt, M1 Max and M1 Ultra take Apple silicon further than ever.
M1 Max CPU Performance vs. Power
M1 Max delivers similar multithreaded CPU performance to the latest 10-core PC desktop chip while using 65 percent less power.
M1 Ultra CPU Performance vs. Power
Compared with the fastest 16-core PC desktop chip, M1 Ultra delivers up to 90 percent higher performance in the same power envelope. And M1 Ultra can deliver the PC chip’s peak performance while using 100 watts less power.
M1 Max GPU Performance vs. Power
At its peak, M1 Max delivers similar performance to one of the most popular discrete GPUs while using one-third the power.
M1 Ultra GPU Performance vs. Power
At its peak, M1 Ultra delivers faster performance than the highest-end GPU available while using 200 watts less power.
