Mac Pro M2 Ultra 2023

The Rack-Mountable Mac Pro "M2 Ultra" models share identical internal components to their tower counterparts, but feature a different chassis design (designed to be slid into a 5U rack), have different identifiers, and are more expensive.

This particular configuration, the Mac Pro "M2 Ultra" 24-Core CPU/76-Core GPU (Rack-Mountable) -- features a 3.68 GHz Apple M2 Ultra processor with twenty four cores (sixteen performance cores and eight efficiency cores), a 76-core GPU, a 32-core Neural Engine, a "Media Engine" that provides hardware acceleration for video encoding and decoding, 64 GB of "unified" onboard RAM, and a 1TB SSD that officially can be upgraded later.

External connectivity options include two Thunderbolt 4 ports on the front and four Thunderbolt 4 ports on the back along with two USB-A ports, two HDMI ports, two 10-Gigabit Ethernet ports, and a 3.5 mm headphone jack. It has 802.11ax (Wi-Fi 6E) and Bluetooth 5.3, too.

Internal connectivity options include one USB-A port and two Serial ATA ports too as one half length x4 PCI Express Gen 3 slot occupied by an Apple I/O card and six full-length PCI Express Gen 4 slots (two x16 slots and four x8 slots).

Featuring the top-tier configuration of the M2 Ultra chip, this rack-mountable model embodied the pinnacle of Apple Silicon's performance capabilities. [27, 28, 29] The 76-core GPU was specifically designed for the most graphically demanding workflows, such as 3D rendering, machine learning, and 8K video editing. [27] Its staggering performance truly met enterprise-class demands. [27, 29] While it maintained the legacy of PCIe expandability from the Intel era, the inability for users to swap GPUs or upgrade RAM sparked considerable debate. [8] Nonetheless, its raw processing power, energy efficiency, and the convenience of a rack-mountable form factor offered unparalleled value in specific professional environments. [8, 20, 28]
