Product Features
Technical Overview
At the core of the Cubi 5 is the Intel Core i5-1235U, a 12th Gen mobile processor with 10 cores (2 Performance + 8 Efficient) and 12 threads. This CPU provides a balance of single-threaded speed and multi-threaded efficiency, supported by Intel's hybrid architecture. The system supports up to 64 GB of DDR4-2666 memory across two SODIMM slots, allowing for substantial multitasking headroom.
Connectivity is a strong suit, with dual Ethernet (2.5GbE and Gigabit), Wi-Fi, Bluetooth, and a Thunderbolt 4 port for high-speed data transfer and display output. Four USB 3.2 Gen 2 ports ensure ample peripheral connectivity. The integrated Intel UHD Graphics handles display output via HDMI and Thunderbolt, suitable for dual-monitor office setups.
