16GB vs 8GB Mini PC Specs
Memory capacity
The Apple Mac mini M6 includes 16GB of unified memory. This configuration offers 170GB/s of memory bandwidth, which Apple states helps accelerate tasks for AI workloads and allows quick access to large media files. In contrast, the Lenovo ThinkCentre M720Q comes with 8GB of DDR4 RAM. While sufficient for basic multitasking and web browsing, this amount is half that of the Mac mini. If you plan to run multiple heavy applications simultaneously or use large language models locally, the 16GB option provides more headroom. The 8GB setup may require closing background apps more frequently to maintain performance.
Processor performance
Apple equips the Mac mini M6 with its custom M6 chip. This processor features a Dual 16-core Neural Engine and next-generation CPU architecture designed for responsive performance and AI capabilities. The Lenovo ThinkCentre M720Q uses an Intel Core i5-8400T, which is an 8th Gen Hexa-Core processor. This Intel chip is older and geared toward standard business productivity and everyday tasks. The M6 chip generally offers higher performance per watt and specialized AI acceleration, whereas the i5-8400T is a conventional consumer processor. Your choice depends on whether you need specialized AI processing or standard desktop computing power.

This version of Windows includes advanced security features and is standard for business environments. If your workflow relies on Windows-specific software or enterprise management tools, the Lenovo is the better fit. If you prefer the macOS ecosystem or Apple-exclusive AI features, the Mac mini is the appropriate choice.
Storage speed
The Apple Mac mini M6 includes a 512GB SSD. Apple notes that this storage is up to 2x faster than previous generations, which helps in quickly accessing large media files and accelerating AI tasks. The Lenovo ThinkCentre M720Q comes with a 250GB NVMe M.2 SSD. NVMe drives are generally fast, but the Mac mini offers double the storage capacity. The 512GB space on the Apple device allows you to store more data locally without relying on external drives. For users who work with large video files or extensive libraries, the larger and faster storage on the Mac mini is advantageous.
Connectivity
The Apple Mac mini M6 features three Thunderbolt 4 ports, an HDMI port, and a 2.5Gb Ethernet port on the back. It also supports Wi-Fi 7 and Bluetooth 6 via the Apple-designed N1 wireless chip. The Lenovo ThinkCentre M720Q includes a WiFi and Bluetooth adapter, though specific generation standards are not detailed in the provided data. The Mac mini offers more high-speed expansion options with Thunderbolt 4 and faster wired networking with 2.5Gb Ethernet. This allows for quicker data transfers and more versatile peripheral connections compared to the standard connectivity found on the Lenovo model.
