At what Xfinity Internet download/upload speed is DOCSIS 3.1 modem useful?

I currently have a Motorola MB7621 DOCSIS 3.0 cable modem that should support up to 600Mbps.  I currently have less than 200Mbps.

Would a DOCSIS 3.1 modem be of any use for Xfinity service with speed less than 1Gbps?  

When would Active Queue Management (AQM) take effect?
Thank you.

DOCSIS 3.1 is only needed for the Gigabit speed tier. It is more expensive overkill for anything else.
