Interesting to see there are some great performance wins for radeon in Xonotic High test when compared with fglrx from january . Seems like 7850 and 6870 with radeon there has nearly double performance
I wasn't able to find any benchmarks with the 260X and 3.14 kernel, so this must have been something Michael encountered at some other point. Could be a red herring, I guess, or maybe he's talking about the performance regressions (HyperZ ?) he covered recently, although if that were the case then 260X would still be much much faster than what we see here..
Assuming Ubuntu 14.04 didn't pick up the CI dpm fixes from the 3.14 kernel the performance in this article isn't out of line, so all we're talking about is Michael's comment about seeing similar issues with the 3.14 kernel. That's the part that doesn't sound right, without more details we're really just all guessing at the moment.
We know from the Kaveri benchmarks that enabling dpm on CI makes the expected difference in performance.

"CIK" stands for the Sea Islands series? Why this name?
I guess the "CI" is for "Sea Islands" and because "SI" was already used for "Southern Islands". What does the "K" means?
