Quad-LAN vs Dual LAN Specs
Processor performance
The Glovary Fanless Quad-LAN Mini PC uses an Intel Celeron J4125 processor with four cores and four threads, running up to 2.7 GHz. This quad-core design handles multiple virtual machines and complex routing tasks more efficiently. The Glovary Fanless Dual LAN Industrial Mini PC relies on a Celeron N2840 processor with only two cores and two threads, clocked at 2.58 GHz. The N2840 has a lower thermal design power of 7.5W, which reduces heat output but limits multitasking capability. For heavy industrial workloads, the J4125 offers superior processing power and thread count.
Networking ports
Network connectivity is a primary differentiator between these two units. The Quad-LAN model provides four Intel i211 Gigabit Ethernet ports, enabling advanced multi-LAN routing, firewall rules, and virtualization setups. This allows you to segment networks easily without needing external switches. The Dual LAN model offers only two Gigabit Ethernet ports. While sufficient for basic routing or simple firewall applications, it lacks the redundancy and segmentation options of the four-port version. If your project requires multiple isolated network interfaces, the Quad-LAN unit is the clear choice.
Memory technology
Both systems come with 8GB of installed RAM, but they use different memory standards. The Quad-LAN Mini PC utilizes DDR4 SO-DIMM memory, which supports speeds up to 32GB of expansion. DDR4 is generally faster and more energy-efficient than older standards. The Dual LAN Industrial Mini PC uses DDR3L memory, with a maximum capacity of 8GB. DDR3L is an older, low-voltage standard that may offer slightly higher latency. For future-proofing and bandwidth, the DDR4 slot in the Quad-LAN model is the superior option.
Display outputs
Video output capabilities differ significantly between the two chassis. The Quad-LAN Mini PC features integrated UHD Graphics 600, supporting 4K display output at 60Hz. This allows for high-resolution monitoring on a single screen. The Dual LAN Industrial Mini PC provides HD and VGA outputs. These older interfaces are suitable for basic monitoring but lack the resolution and modern connectivity of HDMI or DisplayPort. If you need to connect a modern high-resolution monitor for management tasks, the Quad-LAN model provides better visual clarity.
Physical dimensions
Both units are compact and fanless, but their footprints vary. The Quad-LAN Mini PC measures 6.97 inches in length, 4.92 inches in width, and 2.17 inches in height, weighing 1.2 kg. The Dual LAN Industrial Mini PC is slightly shorter at 6.1 inches in length, with the same width but a taller profile at 2.56 inches in height, weighing 2.65 pounds. The Quad-LAN model is lighter and flatter, making it easier to mount in tight spaces. The Dual LAN model is taller, which may affect clearance in certain industrial enclosures.
Which Mini PC Suits Your Network Needs
Users needing four network interfaces
You should choose the Quad-LAN model if your setup requires four Gigabit Ethernet ports. The Intel Celeron J4125 processor provides four cores for handling multiple virtual machines or complex routing tasks. This configuration supports higher network speeds and smoother data transfer for demanding industrial or firewall applications.
Users preferring dual display output
Choose the Dual LAN model if you need to connect two monitors simultaneously. It features both HD and VGA ports for dual display output. While it has only two Ethernet ports, the Intel Celeron N2840 processor handles basic industrial tasks efficiently, making it suitable for simpler edge computing or monitoring roles.
Users prioritizing raw processing power
The Quad-LAN Mini PC offers superior processing power with its quad-core J4125 CPU. This processor runs up to 2.7 GHz, providing better performance for multi-VM workloads compared to the dual-core N2840 in the other model. If your network security or virtualization tasks are intensive, this extra core count matters.
