With a faster CPU and GPU, plus support for even more unified memory, M2 Ultra takes Mac performance further than ever
Apple today announced M2 Ultra, a new system on a chip (SoC) that delivers huge performance increases to the Mac and completes the M2 family. M2 Ultra is the largest and most capable chip Apple has ever created, and it makes the new Mac Studio and Mac Pro the most powerful Mac desktops ever made. M2 Ultra is built using a second-generation 5-nanometer process and uses Apple’s groundbreaking UltraFusion technology to connect the die of two M2 Max chips, doubling the performance.
M2 Ultra consists of 134 billion transistors — 20 billion more than M1 Ultra. Its unified memory architecture supports up to a breakthrough 192GB of memory capacity, which is 50 percent more than M1 Ultra, and features 800GB/s of memory bandwidth — twice that of M2 Max. M2 Ultra features a more powerful CPU that’s 20 percent faster than M1 Ultra, a larger GPU that’s up to 30 percent faster, and a Neural Engine that’s up to 40 percent faster.1 It also features a media engine with twice the capabilities of M2 Max for blazing ProRes acceleration. With all these advancements, M2 Ultra takes Mac performance to a whole new level yet again.
Industry-Leading UltraFusion Technology
M2 Ultra is built from two M2 Max dies connected through UltraFusion, Apple’s industry-leading, custom-built packaging technology. UltraFusion uses a silicon interposer that connects the dies with more than 10,000 signals, providing over 2.5TB/s of low-latency interprocessor bandwidth.
UltraFusion’s architecture enables M2 Ultra to appear as a single chip to software. This means code doesn’t need to be rewritten to utilize the extreme performance of M2 Ultra and makes UltraFusion unlike anything else in the industry.
Advanced Custom Technologies Supercharge Machine Learning, Video, and More
M2 Ultra integrates Apple’s latest custom technologies right on the chip, maximizing performance and efficiency:
- M2 Ultra features a 32-core Neural Engine, delivering 31.6 trillion operations per second, which is 40 percent faster performance than M1 Ultra.
- The powerful media engine has twice the capabilities of M2 Max, further accelerating video processing. It has dedicated, hardware-enabled H.264, HEVC, and ProRes encode and decode, allowing M2 Ultra to play back up to 22 streams of 8K ProRes 422 video — far more than any PC chip can do.
- The display engine supports up to six Pro Display XDRs, driving more than 100 million pixels.
- The latest Secure Enclave, along with hardware-verified secure boot and runtime anti-exploitation technologies, provides best-in-class security.
