Key Considerations When Choosing
- Built-in Port vs. Adapter: Always prioritize built-in RJ-45 (like ThinkBooks/Legion) for reliability. USB-C docks or dongles add cost and bulk.
- Speed: Business/Pro models (e.g., ThinkBook 16p) may offer faster 2.5GbE ports; standard 1GbE suffices for most.
- Use Case: For heavy multitasking, simulation, or video editing, prioritize Ryzen 9/Ultra 9 + RTX GPU (ThinkBook 16p/Legion). For mobility and office work, opt for thinner models (ThinkBook 14+).
- Expandability: ThinkBooks stand out with dual RAM slots and dual SSD slots – vital for future upgrades.
Conclusion
For professionals needing balance: ThinkBook 16p offers top-tier processing, graphics, a large color-accurate screen, and essential RJ-45 in a durable chassis.
For max portability and connectivity: ThinkBook 14+ 2025 is unmatched with its RJ-45, Thunderbolt, MIL-STD toughness, and lightweight design.

For low-latency gaming: High-end Lenovo Legion models provide powerful specs and dedicated gaming Ethernet.
Always verify port presence in specifications – "Ultrabooks" like many Acer Swift/Slim models often omit RJ-45.
