More power in the same small box
Apple’s smallest desktop computer was updated in October 2024 with a smaller chassis, front-mounted USB-C ports, and a choice between the M4 and M4 Pro chips. The base model uses a 10-core CPU and a 10-core GPU, with support for up to 32 GB of shared memory. Choose M4 Pro and you get up to 14 CPU cores, 20 GPU cores, and 64 GB of memory, with more than double the memory bandwidth.
Memory bandwidth and ports
When editing heavy video or working with AI-based image processing, memory bandwidth matters. M4 delivers 120 GB/s, while M4 Pro reaches about 273 GB/s. The more powerful model also switches the rear I/O to Thunderbolt 5 connections that can handle 120 Gb/s in one direction — ideal for external PCIe storage or multi-display setups.

When M4 Pro is the right choice
If you work with code compilation, 3D rendering, or music production with hundreds of tracks, the extra performance cores make a noticeable difference. For web browsing, writing, and hobby-level video work, M4 is more than enough.
Expand your desktop with Satechi Stand & Hub
Whichever model you choose, the port selection up front is modest. Satechi’s Stand & Hub works as both a stand and an expansion hub: SD card reader, three USB-A ports, audio output, and an internal NVMe slot that takes up to 4 TB and delivers up to 10 Gb/s. The design draws heat away from both the computer and the SSD, and its shape follows the lines of the Mac mini, so the whole setup feels like a single unit.

Summary
Choose M4 for silence and value; choose M4 Pro when every second in the export window counts. Add Satechi’s hub for more ports and hidden, fast storage without compromising the look.
FAQ
Which RAM option should I choose?
M4 supports 16–32 GB, and M4 Pro up to 64 GB. For DaVinci Resolve or Xcode projects with more than 20,000 files, at least 32 GB is recommended.
Does the M4 model have Thunderbolt 5?
No. Only M4 Pro gets Thunderbolt 5; M4 keeps Thunderbolt 4, along with convenient front USB-C ports.
Can I replace the SSD later?
The Mac mini’s internal SSD is soldered in place. The Satechi hub, however, lets you replace the NVMe drive yourself.
How big is the performance difference from M2?
CPU performance in M4 is up to 50 percent higher, and the graphics get hardware ray tracing.
