Apple unveils M1 Ultra, the world’s most powerful chip for a personal computer
Apple today announced M1 Ultra, the next giant leap for Apple silicon and the Mac. Featuring 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
Unprecedented Performance and Power Efficiency
M1 Ultra features an extraordinarily powerful 20-core CPU with 16 high-performance cores and four high-efficiency cores. It delivers 90 percent higher multi-threaded performance than the fastest available 16-core PC desktop chip in the same power envelope. Additionally, M1 Ultra reaches the PC chip’s peak performance using 100 fewer watts.2 That astounding efficiency means less energy is consumed and fans run quietly, even as apps like Logic Pro rip through demanding workflows, such as processing massive amounts of virtual instruments, audio plug-ins, and effects.
For the most graphics-intensive needs, like 3D rendering and complex image processing, M1 Ultra has a 64-core GPU — 8x the size of M1 — delivering faster performance than even the highest-end PC GPU available while using 200 fewer watts of power.

Apple’s unified memory architecture has also scaled up with M1 Ultra. Memory bandwidth is increased to 800GB/s, more than 10x the latest PC desktop chip, and M1 Ultra can be configured with 128GB of unified memory. Compared with the most powerful PC graphics cards that max out at 48GB, nothing comes close to M1 Ultra for graphics memory to support enormous GPU-intensive workloads like working with extreme 3D geometry and rendering massive scenes.
The 32-core Neural Engine in M1 Ultra runs up to 22 trillion operations per second, speeding through the most challenging machine learning tasks. And, with double the media engine capabilities of M1 Max, M1 Ultra offers unprecedented ProRes video encode and decode throughput. In fact, the new Mac Studio with M1 Ultra can play back up to 18 streams of 8K ProRes 422 video — a feat no other chip can accomplish.4 M1 Ultra also integrates custom Apple technologies, such as a display engine capable of driving multiple external displays, integrated Thunderbolt 4 controllers, and best-in-class security, including Apple’s latest Secure Enclave, hardware-verified secure boot, and runtime anti-exploitation technologies.
