The Callaway Rogue X Irons are an extreme distance package.
You will hit them further. Probably at least one club length longer.
The lofts are stronger, but are there implications?

Although the loft of a Rogue X #7 Iron is only 27°, that is no longer the relevant number.
There are a couple of additional data points we need to examine.

The Rogue X is made with lightweight, but strong components.
Discretionary weight is created. Designers can go to work on making it easier to launch the ball higher.

Come and hit your current #8 Iron, and then your current #6 Iron, and let’s record the key data. Then hit a Callaway Rogue ‘X’ #7 Iron.
You’re going to get a surprise. And that surprise will extend beyond the added distance, to the improvement in consistency.
