M3 Ultra features a 32-core CPU, an 80-core GPU, double the Neural Engine cores, Thunderbolt 5, and support for the most unified memory ever in a personal computer. CUPERTINO, CALIFORNIA Apple today announced M3 Ultra, the highest-performing chip it has ever created, offering the most powerful CPU and GPU in a Mac, double the Neural Engine cores, and the most unified memory ever in a personal computer. M3 Ultra also features Thunderbolt 5 with more than 2x the bandwidth per port for faster connectivity and robust expansion. M3 Ultra is built using Apple's innovative UltraFusion packaging architecture, which links two M3 Max dies over 10,000 high-speed connections that offer low latency and high bandwidth. This allows the system to treat the combined dies as a single, unified chip for massive performance while maintaining Apple's industry-leading power efficiency. UltraFusion brings together a total of 184 billion transistors to take the industry-leading capabilities of the new Mac Studio to new heights. "M3 Ultra is the pinnacle of our scalable system-on-a-chip architecture, aimed specifically at users who run the most heavily threaded and bandwidth-intensive applications," said Johny Srouji, Apple's senior vice president of Hardware Technologies. "Thanks to its 32-core CPU, massive GPU, support for the most unified memory ever in a personal computer, Thunderbolt 5 connectivity, and industry-leading power efficiency, there's no other chip like M3 Ultra." Ultra Performance and Efficiency M3 Ultra provides the most performance of any Mac chip, while maintaining the industry-leading power-efficiency of Apple silicon. It features up to a 32-core CPU with 24 performance cores and eight efficiency cores, delivering up to 1.5x the performance of M2 Ultra, and up to 1.8x that of M1 Ultra. It also has the largest GPU in any Apple chip, with up to 80 graphics cores that bring up to 2x faster performance than M2 Ultra, and up to 2.6x faster than M1 Ultra.^1 The advanced graphics architecture in M3 Ultra features dynamic caching, along with hardware-accelerated mesh shading and ray tracing, so it can fly through the most demanding content creation workloads and games. A powerful 32-core Neural Engine fuels AI and machine learning (ML), and powers Apple Intelligence, the personal intelligence system that puts powerful generative models right at the core of the new Mac Studio. In fact, M3 Ultra is built for AI, including ML accelerators in the CPU, Apple's most powerful GPU, the Neural Engine, and over 800GB/s of memory bandwidth. AI professionals can use Mac Studio with M3 Ultra to run large language models (LLMs) with over 600 billion parameters directly on device, making it the ultimate desktop for AI development.

M3 Ultra delivers the ultimate performance and capabilities of Apple silicon for users running the most extreme pro workflows. Unparalleled Memory The unified memory architecture of M3 Ultra integrates the most high-bandwidth, low-latency memory ever available in a personal computer. Starting at 96GB, it can be configured up to 512GB, or over half a terabyte. This outpaces the memory available in today's most advanced workstation graphics cards, removing limitations for pro workloads that demand large amounts of graphics memory like 3D rendering, visual effects, and AI. Thunderbolt 5 for Next-Generation Connectivity M3 Ultra brings Thunderbolt 5 to Mac Studio for up to 120 Gb/s data transfer speeds -- more than double that of Thunderbolt 4. Each Thunderbolt 5 port is supported by its own custom-designed controller directly on the chip. This provides dedicated bandwidth for each port on Mac Studio, making it the industry's most capable implementation of Thunderbolt 5. Thunderbolt 5 ports on Mac Studio are a game changer for pro users who require faster data transfer speeds for external storage, docking, and hub solutions, and want to be ready for the next generation of expansion chassis. Thunderbolt 5 also enables connecting multiple Mac Studio systems together for workflows that push the limits of content creation and computer science exploration.

Cutting-Edge Technologies Built In In the pursuit of maximizing performance and efficiency, M3 Ultra integrates Apple's advanced technologies right on the chip: * Apple's custom-built UltraFusion packaging technology uses an embedded silicon interposer that connects two M3 Max dies across more than 10,000 signals, providing over 2.5TB/s of low-latency interprocessor bandwidth, and making M3 Ultra appear as a single chip to software. * With 2x the resources of M3 Max, the media engine within M3 Ultra is capable of far more concurrent video processing. The chip offers dedicated, hardware-enabled H.264, HEVC, and four ProRes encode and decode engines, allowing M3 Ultra to play back up to 22 streams of 8K ProRes 422 video. * The display engine supports up to eight Pro Display XDRs, driving more than 160 million pixels. * The Secure Enclave works with hardware-verified secure boot and runtime anti-exploitation technologies to provide state-of-the-art security. M3 Ultra integrates Apple's advanced technologies, including a media engine that offers dedicated, hardware-enabled H.264, HEVC, and four ProRes encode and decode engines. Better for the Environment The power-efficient performance of M3 Ultra helps the new Mac Studio meet Apple's high standards for energy efficiency and reduces the total amount of energy consumed over the product's lifetime. Today, Apple is carbon neutral for global corporate operations and, as part of its ambitious Apple 2030 goal, plans to be carbon neutral across its entire carbon footprint by the end of this decade.
