What's The Difference Between AX20 & AX23 ? While they both have everything same then why they have different model names & numbers?

@terziyski Thank You Very Much For Your Help. Have A Fantastic Day :)

@terziyski Thank you for your answer. I hope this is true as nothing about MU-MIMO is mentioned on their website in my region as well as on box there is nothing mentioning MU-MIMO. Is there any way...

Does it Support 1200Mbps Download & Upload Stream Because In EU Version It Doesn't Have MU-MIMO. So How Can A Single Stream WI-Fi 6 Router Will Deliver 1200 Mbps To One Device? Because All 1200Mbps...
