This is not a radeon improvement, it's a radeonSI improvement, because seems to be r600 it's not affected.

Originally posted by kaprikawn View PostStock coolers have been fine for me up until now. But a while back my fan was making a very loud sound as it spun, so I ordered a Zalman cooler. By the time it arrived the loud noise had disappeared so I never bothered installing it (little did I know that the reason the sound disappeared was because it crapped out).
Then, this weekend, I started playing Watch_Dogs, and was getting 10-20 fps on low settings on a 770 GTX. So I googled 'Diagnose poor gaming performance' or something like that. A forum post I came across said about the CPU fan not spinning, but I didn't take it seriously because I assumed that if the fan didn't spin then it would overheat and cut out, which is what happened years ago when I was running an Athlon. But I installed the monitoring software just to be sure, and to see if there was anything else it could tell me. And sure enough, my CPU temp was at 90 degrees on a light load. I checked my fan and it was static.
The Zalman was a complete PITA to install, but I got it in eventually and now I'm getting 35 degrees under light load. I haven't tested my game again yet, but I'm expecting it to have sorted my issues.
Lesson learned.

But basically you are correct not all AMD's current & legacy (around 600+ chips) are affected by this , only radeonsi 3d driver see performance improvments here (by improvment in kernel), nor r600, nor r300, nor r200 and nor radeon 3d drivers .
