Summary
Apple’s M6 Mac mini gets put through a battery of real-world benchmarks in this hands-on comparison against the outgoing M4 model. The video covers Geekbench scores, browser speed tests via Speedometer, Python-based Mandelbrot rendering, and Xcode compilation times, showing the M6’s new three-tier CPU design (super cores, performance cores, and efficiency cores), a 12-core GPU with dual neural engines, and upgraded Wi-Fi 7 and Bluetooth 6 connectivity.
A major focus is memory bandwidth, since it directly affects how fast large language models run locally. The M4 delivers roughly 112 GB/s in real-world STREAM testing, while the M6 hits around 143-144 GB/s depending on configuration, with Apple’s official specs citing up to 170 GB/s at 32GB of RAM. The video explains how compute (GPU and neural engine strength) and memory bandwidth together determine both the speed and feasibility of running local AI models, distinguishing bandwidth (‘how fast’) from memory capacity (‘whether it runs at all’).
Developers will find practical comparisons for compilation-heavy workflows, including a head-to-head against the M5 Max and even an M1 Ultra Mac Studio. The reviewer notes Thunderbolt 4 remains unchanged on the base model, reserving Thunderbolt 5 for the Pro tier, and previews deeper dives into the M5 Pro and M5 Ultra coming soon.
