MIPS provides highly scalable RISC processor IP

I agree, Mikrotik have largely moved onto the IPQ4000 series for their wireless products and their many of their advanced switches use the switch ASIC's onboard arm core(s) (CRS305, CRS309, CRS317, CRS328, etc) without an external management SoC.

However, some of their advanced switches (CRS312 12 10GbE RJ45, CRS354 48 GbE 4 SFP+ 2 QSFP+, CRS504 4 QSFP28, CRS326 variant with 24 SFP+ 2 QSFP+, etc) will often use a QCA9531 MIPS SoC as their management chip.

I was surprised to see their latest switch, the new CRS504 (4x 100GbE) [0] used a very advanced Marvell switch chip, with a QCA9531 attached to it. MIPS lives!

Huh, I stand corrected :)

I did not realise that the CRS line was using MIPS so much still! The CRS switches I have handy are all using the integrated dual ARM cores.

edit: I assume those switch chip variants don't have integrated ARM cores, and the older Qualcomm MIPS SoCs are presumably ridiculously cheap.
