Is the transmission rate of MU-MIMO faster?

MU-MIMO is a multi-user technology, so in the scenario where both the terminal and the AP are both spatial streams, the maximum transmission rates of SU-MIMO and MU-MIMO are the same.
MU-MIMO mainly affects transmission efficiency, because the spatial streams supported by the terminal are mostly 1 and 2. When the AP supports 4 spatial streams, space flow is wasted. MU MIMO can communicate with multiple terminals at the same time, so that it can be fully utilized. Its spatial stream, so in a multi-user scenario, for APs, its transmission rate can be considered faster.
