Apple Mac Pro “M2 Ultra” 24 CPU/76 GPU (Rack) Specs

About this Mac Pro

The Apple Mac Pro “M2 Ultra” 24 CPU/76 GPU (Rack) was introduced in 2023. The M2 Ultra chip, which is essentially dual M2 Max processors on a single die, is the centerpiece of this Mac Pro. It boasts 134 billion transistors and offers configurations with a 24-core CPU and a choice between a 60-core or 76-core GPU. This immense processing power is capable of handling up to 22 streams of uncompressed 8K video simultaneously, or multitasking between demanding applications that would typically require separate machines.   

In terms of memory and storage, the Mac Pro “M2 Ultra” comes with up to 192GB of unified memory and up to 8TB of solid-state storage. Unlike other Mac desktops, such as the Mac Studio, the storage in this model can be upgraded post-purchase, thanks to SSD slots on the motherboard’s back side. However, it’s important to note that these are proprietary SSDs, and third-party SSDs are not compatible due to SOC encryption.   

The Mac Pro also features extensive expansion capabilities, with six full-length PCI Express 4 slots available for a range of professional hardware needs, from audio recording to studio-grade video gear. An additional half-length PCIe slot can be freed up by removing the standard I/O card.     

For external connectivity, the Mac Pro supports up to eight 4K displays at 60Hz or up to three 8K panels at the same refresh rate. It includes eight Thunderbolt 4 connections, two USB Type-A ports, two HDMI ports, two 10Gbps Ethernet ports, and a 3.5mm headphone jack. Internally, there’s an additional USB-A port and what appear to be two 6Gbps SATA ports, though their specific use wasn’t clarified.   

The Mac Pro also features the latest in wireless connectivity with Wi-Fi 6E and Bluetooth 5.3. It comes with an Apple Magic Keyboard and Magic Mouse.   

The design of the Mac Pro remains largely unchanged from the previous Intel model from 2019, retaining the distinctive “cheese grater” lattice across the front and the slide-off case for easy access to internals. Additionally, there’s an option for a server rackmount setup, and for added mobility, the desktop can be equipped with wheels.
