Tests show that the RB 433 is 2-3 times faster than the previous high-end MikroTik RouterBoard model RB/532. The unit is equipped with three LAN ports and three miniPCI slots, that can support three high-power R52H 802.11a/b/g (~350mW) & UBNT XR / SR cards without any power supply problems that one would get on cheaper boards available from other manufacturers. RB/433 is ideal for medium-load routing tasks, and is optimized for Dual Nstreme.
