In 2019, Apple introduced the Mac Pro with an expandable module design, delighting macOS enthusiasts. Sporting up to 24-core Xeon processors, users could upgrade this PC with up to 64 PCI Express lanes and a maximum of 1.5 TB RAM. Additionally, it featured APX modules configurable with 6 different GPUs and 8 PCIe expansion slots.
However, this design seems unlikely to feature in the rumored 2023 Mac Pro. Earlier this month, Bloomberg's Mark Gurman revealed information stating that the next-generation Mac Pro won't support RAM upgrades. Unlike the 2019 Mac Pro, the new model will have soldered RAM on the M2 Ultra chip's motherboard.
Now, Gurman has reported another potential limitation as Apple integrates Silicon M-series chips into the new-generation Mac Pro. Specifically, he indicates that the upcoming Apple desktop PC also won't support PCIe GPUs.

Since current Apple Silicon Macs lack external GPU support, users are stuck with whatever configuration they purchase from Apple. Nevertheless, Gurman believes that the GPU of the new Mac Pro will be very powerful, with up to 76 cores. Let's anticipate the strength of the new-generation Mac Pro!
