Hello technical wifi experts 

i have deco x60 as per specifications its 2402Mbps on 5GHz band, also x75 is 2402 Mbps on 5Ghz.

however its mentioned as 5 GHz: 2402 Mbps (802.11ax, HE160)

while x60 is mentioned as 5 GHz: 1201 Mbps (802.11ax)

whats the difference in getting this speed, for xe75 does it mean it depends on 160Mhz bandwidth channel to reach this speed  while for x60 its using 80Mhz bandwidth but needs to use 8 spatial streams to get same speed as xe75 ?
