Boasting an impressive 134 billion transistors, the M2 Ultra surpasses its predecessor, the M1 Ultra, by an additional 20 billion transistors. Moreover, its unified memory architecture supports an extraordinary memory capacity of up to 192GB, a groundbreaking 50 percent increase compared to the M1 Ultra, and features an exceptional memory bandwidth of 800GB/s—twice as fast as the M2 Max. Notably, the M2 Ultra offers a 20 percent faster CPU, a larger GPU with up to 30 percent improved performance, and a Neural Engine that achieves a 40 percent speed boost. The media engine of the M2 Ultra also presents double the capabilities of the M2 Max, enabling accelerated ProRes processing. These groundbreaking advancements solidify the M2 Ultra's position as a game-changer in Mac performance.

Johny Srouji, Apple's senior vice president of Hardware Technologies, expressed enthusiasm for the M2 Ultra's capabilities, highlighting its remarkable performance and efficiency, specifically tailored for professional users' demanding workflows. With significant enhancements in CPU, GPU, and Neural Engine performance, coupled with extensive memory bandwidth in a single SoC, the M2 Ultra claims the title of the world's most powerful chip ever developed for personal computers.

At the core of the M2 Ultra lies UltraFusion, a proprietary packaging architecture by Apple that seamlessly connects two M2 Max dies. Employing a silicon interposer, UltraFusion establishes over 10,000 interprocessor signals, enabling exceptional low-latency interprocessor bandwidth exceeding 2.5TB/s. This breakthrough architecture allows the M2 Ultra to appear as a unified chip to software, eliminating the need for code adaptation to harness its extraordinary performance. UltraFusion represents a unique and unparalleled solution within the industry.

The M2 Ultra's performance and power efficiency remain unmatched. Its 24-core CPU consists of 16 next-generation high-performance cores and eight high-efficiency cores, offering an impressive 20 percent increase in performance compared to the M1 Ultra. Mac Studio users will experience up to 50 percent faster video processing when equipped with the M2 Ultra, significantly enhancing their workflow efficiency. Additionally, the M2 Ultra's GPU configuration can be customized with either 60 or 76 next-generation cores, presenting up to 12 additional cores and up to 30 percent improved performance over the already powerful GPU of the M1 Ultra. Users can expect remarkable rendering speeds for 3D effects when utilizing Octane on the M2 Ultra, offering up to three times faster rendering than the M1 Ultra.

Apple's unified memory architecture, a defining characteristic of its silicon technology, plays a pivotal role in delivering exceptional bandwidth, low latency, and unparalleled power efficiency. The M2 Ultra boasts an outstanding system memory bandwidth of 800GB/s, surpassing anything found in traditional PCs. Furthermore, it supports a massive 192GB of unified memory, enabling workflows that were previously unattainable on PC platforms. The M2 Ultra's capabilities allow for the training of large-scale machine learning workloads on a single system, surpassing the processing potential of even the most powerful discrete GPUs.

The M2 Ultra integrates Apple's latest custom technologies, maximizing both performance and efficiency. Featuring a 32-core Neural Engine, it achieves an impressive 31.6 trillion operations per second—40 percent faster than the M1 Ultra. The media engine offers twice the capabilities of the M2 Max, resulting in accelerated video processing. It incorporates dedicated hardware-enabled H.264, HEVC, and ProRes encode and decode, enabling the M2 Ultra to effortlessly play back up to 22 streams of 8K ProRes 422 video—an accomplishment unmatched by any PC chip. The display engine of the M2 Ultra supports up to six Pro Display XDRs, effortlessly driving over 100 million pixels. Apple ensures best-in-class security with its latest Secure Enclave, coupled with hardware-verified secure boot and runtime anti-exploitation technologies.

Apple's commitment to environmental responsibility remains unwavering. The power-efficient performance of the M2 Ultra allows for exceptional capabilities without compromising environmental sustainability. Apple has achieved carbon neutrality for its global corporate operations, and by 2030, aims to achieve net-zero climate impact across all aspects of its business, including manufacturing supply chains and product life cycles. As a result, every chip created by Apple, from design to manufacturing, will be 100 percent carbon neutral.

With the incorporation of the M2 Ultra into the new Mac Pro, Apple has successfully completed its transition to Apple silicon, revolutionizing the laptop and desktop experience. The Mac enters a new era of performance and innovation, driven by the continued advancement of Apple's silicon technology.
