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/60-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 60-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).

As the rack-mountable version of the Apple Silicon-powered Mac Pro, this model condensed phenomenal CPU and GPU performance into a 5U chassis. The M2 Ultra chip demonstrated superior power efficiency and processing capability in many tasks compared to its Intel Xeon predecessors. While it retained PCIe Gen 4 slot expansion, the lack of user-swappable GPU options and the move to onboard unified RAM were significant changes from the previous generation, leading to a divided reception. It was an ideal choice for users seeking pure computational power and I/O expansion in a rack environment, but those who valued broad graphics card flexibility lamented the reduced options.
