Specs: Processor and Memory
processor
The WEIDIAN model uses an Intel Core i5-8350U processor, which is an eighth-generation chip designed for higher performance in industrial and office environments. The UDPTCP unit relies on a dual-core Celeron N2840 with a maximum turbo frequency of 2.58 GHz. The i5-8350U offers significantly more computational power than the N2840, making it better suited for multitasking and demanding applications. The Celeron is sufficient for basic routing or lightweight tasks, but the i5 provides a clear advantage in raw processing speed and efficiency for complex workloads.
memory
Memory configurations differ significantly between the two units. The WEIDIAN Mini PC comes with 8 GB of RAM pre-installed, ready for immediate use with Windows 11 Pro. The UDPTCP model is sold without RAM in its base configuration, requiring you to purchase and install DDR3L 1333MHz memory separately. While the UDPTCP supports expansion, the WEIDIAN offers a complete out-of-the-box experience with modern memory standards. If you need a system that works immediately without additional hardware purchases, the WEIDIAN configuration is more practical.
storage
Storage options also highlight a major difference. The WEIDIAN includes a 512 GB SSD, providing ample space for the operating system and applications. The UDPTCP is listed with no SSD in its base spec, requiring you to add storage via its MSATA socket or SATA interface. The WEIDIAN also supports dual storage expansion with an M.2 slot and a 2.5-inch bay. For users who want a ready-to-use system with fast storage, the WEIDIAN is the superior choice, whereas the UDPTCP requires extra investment in drives.
networking
Both mini PCs feature dual gigabit Ethernet ports, making them suitable for soft router or firewall applications. The UDPTCP uses Realtek RTL8106E/RTL8111H chips for its 1000M LAN connections. The WEIDIAN also provides two RJ45 Gigabit Ethernet ports. Both units support Wake on LAN and PXE boot, which are essential for network management tasks. Since both offer identical dual-gigabit connectivity and similar network features, there is no significant performance difference in their networking capabilities for standard industrial or home lab use.
form factor
Physical dimensions and weight vary between the two models. The WEIDIAN is compact, measuring 6.69 x 4.96 x 2.28 inches and weighing 2.43 pounds. It supports VESA mounting for space-saving setups. The UDPTCP weighs 4 pounds, making it noticeably heavier. The UDPTCP does not list specific external dimensions in the provided data, but its higher weight suggests a more substantial build. For users prioritizing lightweight portability or easy VESA mounting behind displays, the smaller and lighter WEIDIAN offers a clear practical advantage.
Choose the right mini PC for your needs
Users needing immediate Windows 11 and storage
The WEIDIAN unit includes 8 GB of RAM and a 512 GB SSD, ready for immediate use with Windows 11 Pro. This configuration saves you from purchasing separate components. The Core i5-8350U processor offers more processing power than the N2840, making it better for multitasking in office or light industrial environments without additional setup.
Users building custom firewalls or Linux systems
The UDPTCP model is ideal if you plan to install Linux, OPNsense, or ESXI yourself. It comes without RAM or SSD, allowing you to select specific memory and storage types. The dual gigabit Ethernet ports and RS232 COM ports support industrial networking and legacy device connectivity, providing a flexible base for custom software deployments.
Users prioritizing compact size and lightweight design
The WEIDIAN PC weighs 2.43 pounds and measures 6.69 x 4.96 x 2.28 inches. This compact form factor allows for VESA mounting behind monitors, saving desk space. The UDPTCP unit is heavier at 4 pounds. If you need a smaller, lighter device that is ready to run out of the box, the WEIDIAN is the practical choice.
