RB433GL and RB433AH differences

With regards to new products launched and apart of the differences illustrated below from the official brochure, another major point is the architecture:

RB433GL → AR7161
RB433AH → MIPS-BE

Which are the the differences between these architectures?
Any pros/cons?

the processor is the same, AR7161, the switch chip is no longer ICplus now is a new atheros switch chip

the processor is the same, AR7161, the switch chip is no longer ICplus now is a new atheros switch chip

Is that switch chip the same as in RB435G (Atheros-8316) ?

RB433GL → AR7161
RB433AH → MIPS-BE

that’s wrong, both of them are same architecture (MIPS-BE). Both of them have same CPU (AR7161).

In the brochure there is an extra called “reset switch”.
How is it working? Should we expect the switch to stop function and under what circumstances?
Please give some more info.

all routerboards have a reset button. hold the button while booting to either run Netinstall mode, or just reset RouterOS settings to defaults.

OK, my misunderstanding.

What is MTU on Ethernet ports on RB433GL?
