Lenovo vs KAMRUI Mini PC Specs
processor performance
The Lenovo ThinkCentre M720Q uses an Intel Core i5-8400T, an 8th-generation hexa-core processor. This older chip is designed for low power consumption, making it suitable for basic office tasks. In contrast, the KAMRUI E3B features the AMD Ryzen 5 7530U. This is a newer Zen 3 architecture chip with a higher boost clock of up to 4.5GHz. The KAMRUI processor offers significantly better single-thread performance, which improves responsiveness for web browsing and document editing. For modern multitasking, the KAMRUI CPU provides a clear advantage in speed and efficiency over the Lenovo's older silicon.
memory type
Both systems come equipped with 16GB of RAM, which is sufficient for everyday productivity and light multitasking. However, the technology differs between the two. The Lenovo ThinkCentre M720Q utilizes standard DDR4 memory, which is widely compatible and generally upgradeable in many mini PC designs. The KAMRUI E3B uses LPDDR4X memory. While this type of RAM is more power-efficient, the KAMRUI specifications explicitly state it is non-upgradeable. If you require the ability to expand your memory later, the Lenovo's DDR4 configuration offers more flexibility. For fixed configurations, both provide equal capacity.
storage capacity
Storage options vary slightly between the two units. The Lenovo ThinkCentre M720Q is configured with a 500GB NVMe M.2 SSD. This provides fast load times for your operating system and applications. The KAMRUI E3B offers a 512GB SSD, which is a marginally larger capacity. More importantly, the KAMRUI includes two M.2 slots, allowing for significant storage expansion up to 2TB per slot. The Lenovo data does not specify additional expansion slots beyond the initial drive. For users who need to store large files or media libraries, the KAMRUI provides more immediate space and future upgrade potential.
wireless connectivity
Networking capabilities differ noticeably between these two mini PCs. The KAMRUI E3B is equipped with WiFi 6, which supports speeds up to 2402 Mbps on the 5GHz band. This newer standard reduces latency and handles network congestion better than previous generations. It also includes Bluetooth 5.2 for efficient peripheral connections. The Lenovo ThinkCentre M720Q lists a WiFi and Bluetooth adapter but does not specify the generation. Given the older processor, it likely uses an earlier WiFi standard. For faster wireless downloads and more stable connections in crowded environments, the KAMRUI's modern networking hardware is superior.
operating system
The software environment is a key differentiator for professional users. The Lenovo ThinkCentre M720Q comes pre-installed with Windows 11 Pro. This edition includes advanced security features, domain joining capabilities, and remote desktop hosting, which are essential for business environments. The KAMRUI E3B specifications do not list a pre-installed operating system. You would need to purchase and install a license separately if you require Windows. For users who want a ready-to-work business machine with professional features out of the box, the Lenovo provides a significant advantage with its included OS.
