Compared to the M1, the M2 is up to 1.4x faster, and it features 24GB of unified memory and 100GB/s memory bandwidth. The M2 Pro chip has up to a 12-core CPU with four high-performance cores and eight high-efficiency cores, plus up to a 19-core GPU. The M2 chip in the Mac mini has an 8-core CPU with four high-efficiency cores and four high-performance cores along with an integrated GPU that has 10 cores. The M2 and M2 Pro chips in the Mac mini integrate the GPU, CPU, RAM, and other components.

Everything new is internal, and primarily the result of the M2 chip update. This is the first notable update Apple has made to the Mac mini since the 2020 launch of the M1 model, but there have been no major external design changes to the machine. The new Mac mini models use M2 and M2 Pro chips, with Apple eliminating Intel processors from the Mac mini lineup. For this, you’ll need the same parts and tools above, plus, you’ll need to add in the Optical Bay SATA HDD/SSD Enclosure.Apple in January 2023 introduced two new Mac mini models to replace the previous-generation models with M1 and Intel chips.
