Apple Silicon Mac Pro Has Seven PCIe Expansion Slots, But None Of Them Can Support AMD Radeon GPUs
Omar Sohail
1 hour ago

Apple reused the same chassis for its M2 Ultra-powered Mac Pro, meaning that the workstation would ship with the same seven PCIe expansion slots as the previous model, which featured Intel’s Xeon processors. Unfortunately, suppose you want to connect any AMD Radeon GPUs to the latest machine. In that case, Apple has placed certain limitations that prevent you from doing so, removing one important aspect of having a PCIe expansion slot in the first place.

Apple likely believes that the Mac Pro featuring the 60-core or 76-core GPU options will be more than plentiful
The Mac Pro is currently available to order with the M2 Ultra SoC sporting the 60-core or 76-core GPU configurations. AppleInsider reports that if power users wish to add something more powerful, such as an AMD Radeon GPU, to improve their workflow, they will not be able to. It is worth noting that Apple has incorporated the PCIe Gen 4 standard into its latest model, so accommodating such GPUs should not be a problem. It is likely that the company has enabled a software lock to add expansion cards such as this.

One reason for this limitation is that Apple probably wants to deliver this perception that its M2 Ultra with either the 60-core or 76-core GPU will be more than plentiful to handle whatever graphically demanding task is thrown in its way. Luckily, it is possible to add PCIe-based SSD kits, and Apple is also selling some on its online store. One major benefit of purchasing an Apple Silicon Mac Pro is that customers will not be required to purchase an Afterburner card, so they can save some money in the long run.

The lack of GPU expansion possibilities on the Mac Pro might annoy some potential buyers
This is because the M2 Ultra’s GPU should be powerful enough to get the job done. It may be possible that other expansion cards will be compatible with the Mac Pro, such as networking, but if you have a spare AMD Radeon GPU lying around, you are better off installing it in your Intel-powered Mac Pro if you still own it, or a Windows desktop.
