8-16 port switch - that would put Mikrotik right in the nose of extremely high end switches
i love MikroTik but we have to look at the big picture, i think we are very far from high end, in high end we are seing about 32 x 100g in 1 rack unit in a standalone switch, in modular chassis there are 32 x 100g interface in 1 rack unit slot + 32 x 100g towards the back plane
In hig end there are chassis with 200+ tbps
MikroTik serves us very well but Big Players are 100-200 times ahead
Yeah, the really big players make their own silicon, though merchant silicon is quite good nowadays. I suspect that the best merchant silicon is defacto tied to certain large customers, leaving only older silicon for the rest.
Probably not a coincidence this switch showed up shortly after Qnap's M5216-1T (16 port 25GbE + 1 10GbE, also from Marvell). The 16 port SFP28 silicon group probably got cheaper and more available around now. Looking at it, probably internally similar to a line card setup. That's just a guess from me, though.
