Processor, Ports, and Storage Comparison
Processor performance
Product A uses the Intel J4105 quad-core processor, which runs up to 2.5GHz with a 10W TDP. Product B features the newer Intel Core 6006U, which is a dual-core chip with a 15W TDP. The J4105 offers more physical cores, which can help with multitasking in virtualized firewall environments. The Core 6006U is a newer architecture, potentially offering better single-thread performance. Both chips support AES-NI for hardware-accelerated encryption, a critical feature for firewall throughput. You should choose based on whether you prioritize core count or newer architecture efficiency.
Ethernet connectivity
Product A provides four Intel 2.5GbE LAN ports using the i226-V controller. Product B offers six Intel i226 LAN ports, also supporting up to 2.5GbE speeds. The additional two ports on Product B allow for more complex network topologies, such as separate WAN, LAN, and DMZ interfaces without needing external switches. This extra connectivity is valuable for users managing multiple network segments or requiring higher aggregate bandwidth. Both units ensure stable connections for soft routing and firewall applications. If you need more physical interfaces, Product B is the clear choice.
Storage expansion
Both devices come with 240GB mSATA SSDs and 8GB of DDR4 RAM. However, their expansion capabilities differ significantly. Product A supports up to 512GB on the mSATA slot and does not support HDD expansion. Product B supports up to 2TB on the mSATA slot and explicitly supports HDD expansion via its internal slots. This means Product B can handle larger datasets, extensive logs, or hypervisor virtual machines more easily. If you anticipate needing substantial local storage for network security logs or virtualization, Product B provides much greater flexibility and capacity.
Physical dimensions
Product A measures approximately 5.27 by 4.98 by 1.43 inches and weighs 500g. Product B is larger, measuring 5.4 by 5.1 by 2.2 inches and weighing 1.62kg. The smaller footprint of Product A makes it easier to mount behind a monitor using the included VESA mount. Product B’s larger chassis accommodates more ports and expansion slots, resulting in a heavier build. If space is limited or you prefer a compact setup for your network rack, Product A is more suitable. The larger size of Product B is a trade-off for its extra features.
Power input options
Product A uses a standard DC power port for connectivity. Product B offers dual power input options: a default DC-IN 12V port and an optional Phoenix Terminal power connector. The Phoenix Terminal option allows for more secure and professional wiring, which is often preferred in server or industrial environments. You must purchase the specific power cord separately for the Phoenix Terminal. This flexibility makes Product B more adaptable for custom installations or permanent mounting where vibration resistance is important. Product A remains simpler with its single power interface.
Which firewall mini pc suits you best
Users needing maximum port density
Product B provides six Intel i226 LAN ports, offering significantly more connectivity than Product A's four ports. This extra bandwidth supports complex network topologies and advanced soft routing setups without requiring additional hardware. The increased port count allows for better traffic segmentation and dedicated links for different network segments.
Those requiring higher storage expansion
Product B supports up to 2TB of storage and allows HDD expansion, whereas Product A is limited to 512GB mSATA SSDs. This flexibility is crucial for running hypervisors or storing extensive logs. The dual SO-DIMM slots also allow upgrading RAM to 32GB, providing greater headroom for virtualization tasks.
Users prioritizing processing cores
Product A uses the Intel J4105 quad-core processor, which offers four threads compared to Product B's dual-core configuration. For tasks heavily reliant on multi-threaded performance, such as complex firewall rules or packet inspection, the additional cores provide better throughput. This makes it a stronger choice for pure compute-intensive network security workloads.
