you also don't see anything in the ati changelog that happens in the shared code base and benefits both sides. So if AMD tunes fpr a certain opengl app and that influences the linux side too you won't find it in the linux changelog.
Apart from that - what did Phoronix really test? Quake-based stuff, Specviewperf - but there is a lot more stuff.

The general architecture of the ATI cards has been pretty similar since r600 was released, so i'm not surprised that the drivers were already tuned pretty well. The new DX11 features aren't being used in any of these tests, that would be where i would expect driver improvements to show up. The new 6000 series does finally switch to a new architecture, so it would be more interesting to track that and see if the performance picks up there or not. Same has been true of NVidia, using the same architecture for a long time up until a switch occurred with Fermi.

When was the last time you have seen a change log on linux drivers that said something like:
- 17% increase in performance on Nexiuz on XYZ series cards
- 22% increase in performance on GIMP on XYZ series cards
- 37% increase in performance on ET:QW running in multicard setup on XYZ cards.
Quoting the nvidia 260.89 linux driver relnotes (from 18.10.2010):
Performance
* Increases performance for GeForce GTX 400 Series GPUs in several PC games vs. v258.96 WHQL drivers. The following are examples of some of the most significant improvements measured on Windows 7. Results will vary depending on your GPU and system configuration:

Anyway, what I wanted to add was that I noticed the Win7 part, but still felt it worth quoting since it seems to imply that this also applies on linux (for the subset of games that runs there).

User should use the newer Firepro 8.773.1 and Catalyst 10.12 drivers with the newer Y2010-Y2011 cards. I don't think ATI's current drivers are OpenGL 4.1 compliant (just compatible) yet which help advanced developers push demos and graphics to help sell their software.
