Wifi speed 1750 vs 1300 =433 max?

[Ztdutxjgxgtu]

I am looking into some pci wifi ac,
Eg
1. Asus pce ac56 2anttena 1300mbps (5g 887 mbps)
2. Asus pce ac68 3anttena 1750mbps (5g 1300 mbps)

So the advertise speed = antenna x 433?
The question comes, what is the max speed from One 5g network ? 433mbps on both? Or will it really add up by number of antenna?

It depends on how the 5Ghz network is configured. You can specify a bandwidth of 20, 40, 80Mhz. The 433Mbit is only possible with the 80Mhz setting. Those numbers are just marketing and "your mileage may vary". This is a pretty good article about WIFI -- https://www.duckware.com/tech/wifi-in-the-us.html

A bit complicated in the link...
Assume normal house router ac1750 Dlink defult config, can it make full use the 2/3 antenna? Or just one at a time?
Coz they used to add up speeds that cant be used at same time , eg 2.4g +5g

How many antennas are used depends on the device connecting to the router. There are not many three antenna devices. Phones, tablets and laptops are generally two antennas. Some desktop WIFI cards are three.

The numbers listed are just marketing. Yes they add all possible bandwidth the router MIGHT support. You will never come close to the numbers listed in the name.
