FWIW as someone who’s done a lot of open source work relating to these chipsets, the MR55’s (Hawkeye v1) SoC, in addition to being Draft wifi 6, also had a number of known chipset bugs resulting in a bunch of wifi 5 class features being turned off too (in particular, most forms of beamforming are disabled, which also means things like MU-MIMO effectively don’t work well or at all). So unfortunately in my experience, you will see a performance delta, probably on the order of 20% in the real world, between the MR55 and MR56 simply because of Hawkeye V2 SoC in the MR56 being better and not needing these mitigations.
