Lenovo vs ASUS Mini PC
processor performance
The Lenovo ThinkCentre M720Q uses an Intel Core i5-8400T processor. This is an 8th generation hexa-core chip designed for multitasking and business productivity. It handles web browsing and office apps smoothly. The ASUS Fanless Chromebox 4 relies on an Intel Celeron 5265U. This is a lower-power chip aimed at basic ChromeOS tasks. The i5 provides significantly more processing power for demanding workloads. If you need speed for multiple applications, the Lenovo has the clear advantage. The ASUS is sufficient only for light web use.
memory capacity
Memory determines how many programs you can run at once. The Lenovo ThinkCentre M720Q comes with 16GB of DDR4 RAM. This allows for heavy multitasking without slowing down. The ASUS Fanless Chromebox 4 includes only 4GB of DDR4 RAM. This limit restricts the number of browser tabs and apps you can keep open. For most users, 16GB is the standard for a responsive experience. The Lenovo offers four times the memory of the ASUS. You will notice a difference in smoothness when switching tasks.
storage space
Storage holds your files and operating system. The Lenovo ThinkCentre M720Q features a 500GB NVMe drive. NVMe technology provides fast load times for apps and files. The ASUS Fanless Chromebox 4 has 32GB of eMMC storage. eMMC is slower than NVMe and offers very limited space. You can install few applications on the ASUS before running out of room. The Lenovo provides ample space for documents, media, and software. The difference in capacity and speed favors the Lenovo significantly.
operating system
The operating system defines what software you can run. The Lenovo ThinkCentre M720Q runs Windows 11 Pro. This allows you to install any Windows application, including full desktop versions of Office and specialized business tools. The ASUS Fanless Chromebox 4 runs ChromeOS. This system relies on web apps and Android applications. You cannot run traditional Windows software on the ASUS. If you need specific desktop programs or compatibility with existing Windows workflows, the Lenovo is the only choice.
physical size
Size matters for desk space and mounting. The ASUS Fanless Chromebox 4 is extremely compact. It measures 5.75 inches in length and 4.11 inches in width. It weighs just 2.2 pounds. The Lenovo ThinkCentre M720Q is larger. It measures 19 inches in length and 15 inches in width. It weighs 2.91 pounds. The ASUS is much smaller and lighter. It is easier to hide behind a monitor or mount in tight spaces. The Lenovo is still small compared to desktop towers, but the ASUS is more portable.
