Power to change everything. Say hello to a Mac that is extreme in every way. With the greatest performance, expansion, and configurability yet, it is a system created to let a wide range of professionals push the limits of what is possible. All-New Design Function defines form. Every aspect of Mac Pro is designed in pursuit of performance. Built around a stainless steel space frame, an aluminum housing lifts off, allowing 360-degree access to every component and vast configuration. From there anything is possible. Processor And Memory 8-cores of power. Create without constraint. Mac Pro is designed for pros who need the ultimate in CPU performance. From production rendering to playing hundreds of virtual instruments to simulating an iOS app on multiple devices at once, it's exceedingly capable. At the heart of the system is an Intel Xeon processor with 8-cores - the most ever in a Mac. In addition, large L2 and shared L3 caches and 64 PCI Express lanes provide massive bandwidth in and out of the processor. Engineered to go all out. All the time. Squeezing every possible ounce of performance out of the processor means giving it a lot of power. In this case, over 300 watts. A massive heat sink keeps the system cool, enabling it to run fully unconstrained. Heat pipes move heat away from the chip, dispersing it along aluminum fin stacks. While three axial fans move air through the system. Forget everything you know about memory. A multicore workstation processor needs lots of memory to feed it. Featuring six channels of superfast ECC memory and 12 physical DIMM slots, Mac Pro allows for 48GB of memory. So pros working with large projects, analyzing huge data sets, or running multiple pro applications can make fast work out of all kinds of work. And while typical towers cram memory into hard-to-reach places, Mac Pro utilizes a two-sided logic board, making it easy to access. Up to 2933MHz DDR4 ECC memory Up to 140GB/s memory bandwidth Six-channel memory system 8-Core 16 threads 3.5GHz base 4.0GHz turbo boost 24.5MB cache Expansion Eight PCI Express expansion slots. Go configure. Mac Pro is designed for pros who need to build high-bandwidth capabilities into their systems. With four double-wide slots, three single-wide slots, and one half-length slot preconfigured with the Apple I/O card, it has twice as many slots as the previous Mac tower. Now you can customize and expand in ways never before possible in a single workstation. Graphics Extreme performance. By design. For many pros, a high-performance graphics architecture is critical to their workflows. Especially for tasks like animating 3D film assets, compositing 8K scenes, and building lifelike gaming environments. To give them the highest possible performance and take graphics capabilities to a new level, something groundbreaking was required. Introducing the Mac Pro Expansion Module, or MPX Module. A second connector. An industry first. The MPX Module starts with an industry-standard PCI Express connector. Then more PCIe lanes integrate Thunderbolt and additional power provided to increase capability. With up to 500 watts, the MPX Module has power capacity equivalent to that of the entire previous-generation Mac Pro. Cool. Quiet. Capable. Most GPUs aren't conceived as part of an overall system, so they require their own cooling. The MPX Module is designed as an integrated component of Mac Pro. Its form factor enables a larger heat sink, which works in concert with the machine's internal airflow to quietly dissipate heat. Without a noisy bolted-on fan, heat and decibel levels are kept remarkably low. Radeon Pro W5500X A next-generation graphics card that pairs performance with power efficiency. 5.6 teraflops single precision 11.2 teraflops half precision 8GB of GDDR6 memory 224GB/s memory bandwidth Security and Storage Security taken to new heights. Mac Pro is the most secure tower we've ever built. A Secure Enclave coprocessor provides the foundation for encrypted storage and secure boot capabilities. So you can worry less about protecting your work, code, and intellectual property. And focus more on doing your best thinking. Apple T2 Security Chip. Data on Mac Pro is protected by the Apple T2 Security Chip. It integrates a Secure Enclave coprocessor and discrete controllers into a single chip. It also ensures that the lowest levels of software aren't tampered with and that only operating system software trusted by Apple loads at startup. 1TB Storage. To deliver the fastest possible performance, Mac Pro is built on an all-flash storage architecture. High-Speed Connections Powerful I/O at hand. Mac Pro has extremely high-performance I/O, and lots of it. It begins with four Thunderbolt 3 ports, two USB-A ports, and two 10Gb Ethernet ports. And with every MPX Module you add you get more capability. Connect up to 12 4K displays or up to six Pro Display XDRs from Apple and see your work with over 120 million pixels. It's now easy to expand at will. Rear expansion. With up to 12 Thunderbolt 3 ports, Mac Pro doesn't just have room for more ports than any Mac, it integrates them elegantly with each new module added. Top case. Two convenient ports on the top allow quick and easy connections to your Thunderbolt 3-compatible devices.
