700 devices on 500 controller - Any benefit vs 500?

[anom3]

Simple question:

Does one get any of the benefits of 700 vs 500 when using a 700 device on a 500 controller?

My understanding is between the time 500 and 700 was developed, the EU (where I am) relaxed the max tx power devices can put out a bit and silabs took advantage of this... Will I see slightly better range with 700 devices when connected to a 500 controller?

I am asking because aeotec has 700 series range extenders available. I have 2 of these older ones, 500 series... Will they work a bit better?

I also looked at the FCC images, the internals look very similar (including the antenna).

yes, 700 are better in power consumption. and yes, range will be better even if the controller is 5th gen
