The Radxa X4L, also known as the Palmshell SLiM X4L, is a compact device powered by Intel’s quad-core N100 processor. With features like a 2.5GbE LAN port, Wi-Fi 6E, and dual 4K@30Hz display support, it’s well-suited for multimedia and general-purpose use.

Unlike the Palmshell SLiM X2L released this year, the X4L integrates the Intel Alder Lake-N N100 processor, which offers the following specifications:

• N100 — 4C/4T, (up to 3.40 GHz); 6 MB Cache, 24 EU, Intel UHD Graphics (up to 750 MHz), 6W TDP

Memory options for the X4L range from 8GB to 32GB LPDDR5 at 4800 MT/s. For storage, it includes an NVMe SSD available in configurations from 128GB to 1TB, along with a 32GB eMMC option for OS installation.

Networking features include a 2.5 Gigabit Ethernet port, Intel AX210 Wi-Fi 6E, and Bluetooth 5.3, providing an upgrade from the 1 Gigabit Ethernet and Wi-Fi 5 capabilities on the X2L model. This setup supports faster connection speeds and improved compatibility with newer devices.

Peripheral connectivity is handled by three USB 3.0 ports, one USB 2.0 port, and dual HDMI 2.0 ports, enabling dual 4K displays at 30Hz.

Performance testing by Bret.dk shows that the X4L maintains competitive results among Intel N100-based devices, performing similarly to the Radxa X4 in single-core benchmarks. Multi-core tests indicate a slight advantage for the X4L.

Graphics tests further highlight the benefits of the 64-bit memory bus, with the X4L scoring 15% higher than the X4 at lower resolutions and over 30% higher at 1080p.

Real-world tests demonstrate quicker boot times and a more responsive experience overall. The active cooling system effectively manages heat, though temperatures reached 93°C under intensive loads, which may impact sustained performance.
