How fast is the AC wi-fi in new iMac 5k?

[jordanz]

Trying to decide between two AC wi-fi routers for the refreshed iMac 5k, does anyone know what spec / how fast the AC speed in the iMac is?

I can either get an AC1900 or AC2400 type router, wondering if there will be a speed difference between the two on the iMac (even if it's just relevant to local network transfer speeds).

the max iMac supports is 1300mbps. so AC1900 is enough, it won't be able to take advantage of wave 2 routers.

ac68/time capsule are two top choices.
