M6 Mac mini vs M4 Mac mini: Compact powerhouses compared

Apple has introduced the M6 Mac mini, a compact powerhouse that replaces the M4 version in an unusual update just before the company's main iPhone event. The primary difference lies in the internal specification improvements, maintaining the Mac mini's compact design and footprint. Both models share identical dimensions of 5 inches by 5 inches and a height of 2 inches, with the front-facing ports remaining the same. Notably, the M6 Mac mini retains the same 1.5-pound weight as the M4 model.

The M4 chip in the previous Mac mini boasted a 10-core CPU, a 10-core GPU, and a 16-core Neural Engine. In contrast, the M6 Mac mini features a 2-nanometer M6 chip, marking a significant shift in the compact computer's core architecture. It comes equipped with a 12-core CPU, comprising two super cores, four performance cores, and six efficiency cores.

This new chip is claimed to deliver the world's fastest single-threaded performance. Additionally, the M6 sports a 12-core GPU, and a more powerful Neural Engine featuring Dual 16-core Neural Engines, resulting in a 4.8x speed improvement in LLM prompt processing and twice the performance over the M4. Memory capacity has also been updated, with the M6 offering a base 16GB, 24GB, and 32GB options, similar to the M4.

However, the memory bandwidth has increased from 120GB/s on the M4 to 170GB/s on the M6, which benefits large local AI models and on-device inference. Connectivity for both models remains largely unchanged, with HDMI, three Thunderbolt 4 ports, two front USB-C ports, and a front headphone jack.
