Why did you forget the 1MB L2 cache? 1.4MB vs 1.125MB is just 12% more.

They don't have to score identically to be bandwidth limited, if they are limited in part of the benchmark the score will increase much less than the core count, which is exactly what happens.

No, I am claiming that official results and Anandtech results are not comparable because of compiler flags.
