 It seems a switching chip is Marvell 98DX8332. This switch might also support 2.5GbE and 5GbE although MikroTik doesn't clearly say, because the chip support them and there are their check boxes on the switch's config screen...
-The switch supports dual boot of RouterOS and SwOS, so it can do L3 processing to some extent. Having said that, the processes which aren't handled by the chip are processed by CPU, and what is worse, an internal bandwidth between them is only 1Gbps. Therefore, we had better use it as plain L2 switch, or should keep lightweight L3 usage such as connecting to WAN with simple packet filtering. Otherwise its valuable performance will be completely dead. Fortunately it has enough 10GbE ports, so I think fit to pass on the L3 processes to a superior router with a LAG. AT-x510-28GTX which is a L3 switch I got some time ago will have tears of joy for this application.
