Hello,
The major difference between the devices is the CPU:
- RUT955: Atheros Wasp, MIPS 74Kc, 550 MHz
- RUT956: Mediatek, MT7628, 580 MHz
Another thing to note is that RUT956 does not contain micro SD card slot, which is available on RUT955.
Other than that, these are Identical devices in their features and capabilities, with RUT956 having a slightly faster CPU, which might improve performance.
Despite that, I would like to inform you, that RUT955 has entered product End of Life, meaning that new orders for RUT955 will not be accepted from 31.07.2023, no more units will be produced from 31.12.2023, no software support provided after 31.12.2025.
With that in mind, I would encourage you to consider switching to RUT956.
Best regards,
