The 1800 likely is boosting with xfr as well, those will be old figures they must have got for previous reviews.
The 2xxx chips are on a naff board so prob no xfr and god knows what effect on boost.
So.. we know... nothing
Except they put up a chart with their tested boost results, when you look at it and actually study it their numbers don't add up, you overclock an 1800X by 10% you get a lot more than 3% extra gaming performance, its not 1:1 scaling but its not far off, even the memory scaling on Ryzen is 0.6:1
