The SD25TB4 is built upon the Intel Goshen Ridge (JHL8440) controller, providing 40Gbps Thunderbolt 4 bandwidth. It features an integrated wireless module designed for out-of-band management, allowing for remote firmware updates. Network throughput is supported by a 2.5GbE Realtek RTL8156BG chipset, providing an increased data ceiling compared to standard Gigabit Ethernet ports.
Aggregated specification data confirms a 130W Power Delivery capability when paired with compatible ecosystem laptops, though standard Thunderbolt devices are capped at 90W-100W. The unit supports up to quad-4K display configurations on Windows hosts via high-grade re-timers. Thermal management is assisted by an internal fan, which may engage during high-load power delivery or quad-monitor operation.
- Networking: 2.5GbE RJ45, Internal Wi-Fi for management.
- Chipset: Intel Goshen Ridge (TB4).
- Power: 130W proprietary boost / 100W standard PD.
Material analysis identifies a sustainable design architecture. However, macOS users are restricted to mirrored dual displays via MST unless utilizing the downstream Thunderbolt 4 ports. The unit is designed to function as a network-attached endpoint for managed enterprise environments.
Enterprise environments requiring remote IT management and 2.5GbE connectivity should prioritize the Dell SD25TB4 Smart Dock for its out-of-band utility.
This advanced hardware represents a transition toward "managed endpoints" in the dedicated home automation controllers and professional docking space.
