ASUS vs Protectli: Key Specs
Processor speed
The ASUS Fanless Chromebox 4 uses an Intel Celeron 5265U processor. This chip is part of the newer Apollo Lake refresh and offers better single-core performance and power efficiency than older designs. In contrast, the Protectli Vault FW4B relies on the Intel Celeron J3160. While this is a quad-core chip, it is an older architecture with lower clock speeds. For general desktop tasks and multitasking, the ASUS processor provides a noticeable speed advantage. The Protectli chip is sufficient for basic networking duties but lags in computational power.
Operating system
The ASUS unit comes pre-installed with ChromeOS. This operating system is designed for web-based applications and offers a simple, secure interface out of the box. You do not need to configure the software to start using it for browsing or office tasks. The Protectli Vault arrives with no operating system installed. It is designed for users who want to install open-source firewall software like pfSense or OPNsense. This makes the Protectli ideal for network security roles but requires technical knowledge to set up. The ASUS is ready for immediate general use.
Networking ports
Networking capabilities differ significantly between these two mini PCs. The Protectli Vault FW4B features four Intel Gigabit Ethernet ports. This configuration is essential for firewall appliances that need to manage multiple network zones, such as LAN, WAN, and DMZ connections. The ASUS Chromebox 4 does not list multiple Ethernet ports in its specifications. It focuses on connectivity via USB-C, HDMI, and legacy RS232 interfaces. If you need to route traffic through multiple network segments, the Protectli hardware is the only viable option.
Memory type
Both systems include 4GB of installed RAM, but the memory technology varies. The ASUS Fanless Chromebox 4 uses DDR4 memory. This newer standard offers higher bandwidth and better energy efficiency compared to its predecessor. The Protectli Vault uses DDR3L memory. While 4GB is adequate for lightweight tasks on either machine, the DDR4 in the ASUS unit supports faster data transfer rates. This difference is more relevant for the desktop environment of the Chromebox. For the firewall role of the Protectli, the memory speed difference is less critical but still favors the ASUS architecture.
Storage interface
Storage technology impacts longevity and speed. The ASUS Chromebox 4 utilizes 32GB of eMMC storage. eMMC is a flash storage standard commonly found in mobile devices and entry-level laptops, offering decent speed for booting an operating system and loading apps. The Protectli Vault uses 32GB of mSATA SSD storage. The mSATA interface connects directly to the PCIe bus, typically providing faster read and write speeds than eMMC. This makes the Protectli slightly quicker at handling small file operations, which can benefit firewall logging and configuration tasks.
Physical dimensions
Size matters when mounting these devices. The ASUS Chromebox 4 measures 5.75 inches in length, 4.11 inches in width, and 0.89 inches in height. It is a low-profile slab designed for VESA mounting behind monitors. The Protectli Vault is slightly taller at 1.5 inches but shorter in length at 4.5 inches. Both are compact, but the ASUS form factor is optimized for display attachment. The Protectli’s taller chassis may offer slightly better airflow distribution in confined spaces, though both are fanless. The ASUS is more discreet for desktop setups.
Which Mini PC Fits Your Needs
Office workers needing a simple desktop
Choose the ASUS Fanless Chromebox 4 for everyday computing. It runs ChromeOS, which provides a familiar interface for web browsing and document editing. The Intel Celeron 5265U processor handles light multitasking efficiently. You get WiFi 6 for stable connectivity and USB-C ports for modern peripherals. This device is ready to use out of the box without extra configuration.
Network administrators building a firewall
Select the Protectli Vault FW4B if you need to secure your network. It features four Intel Gigabit Ethernet ports, allowing you to segment traffic between WAN and LAN connections. The unit supports open-source firewall software like pfSense or OPNsense. Its compact fanless design ensures silent operation in a server rack or home office. You install the OS yourself for maximum control.
Users requiring legacy serial connections
The ASUS Chromebox 4 includes an RS232 port via RJ50 interface. This allows you to connect to older industrial monitors or legacy devices that require serial communication. The fanless aluminum chassis helps maintain stable thermal performance in enclosed spaces. You can also mount it behind a display using VESA mounting holes. This versatility makes it suitable for specialized commercial environments.
