All we know for sure is that the Nest Wifi Points are AC1200 (like the original Google Wifi) and the Nest Wifi Router is AC2200. Consumer AC speed ratings are largely bogus, but this should translate into one 2.4GHz 2x2 radio and one 5GHz 2x2 radio on the Points as well as one 2.4GHz 2x2 radio with two 5GHz 2x2 radios on the Nest Router.
