The MikroTik RB5009 series is a compact, fanless routing platform designed for high-performance networks. 

With 10G, 2.5G, PoE options, and indoor or outdoor models, it fits studios, offices, ISPs, and field deployments.

MikroTik refreshed its most popular wired router without changing the price. This post compares the classic hEX (RB750Gr3) with the new hEX Refresh (E50UG), focusing on hardware changes, real performance gains, and which one actually makes sense to deploy today.

Side-by-side comparison of the legacy MikroTik hEX S and the new hEX S (2025) — CPU, RAM, storage, SFP, PoE, block diagrams, and real test results to help you choose the right router.
