First thanks for article
Very good article, opensource vs privative drivers comparative in all brands its really neccesary for all users on linux
But i suggest if you have test wine in all brands used in opensource vs privative drivers comparative is really neccesary and could give users some information about actual wine state in different brands hardware (AMD/INTEL/NVIDIA)
And you could test games with different engines:
Assasins Creed - Call of Duty - Unreal 3 - Farcry and many others
If you have test actual app state on wine could entry on wineappdb
Thanks for your attention
Well spot. :/

However, Catalyst is doing a really good job for now (apart from the relative performance to older ASICs).
Well, you can *buy* GCN ASICs for more than 1.5 years by now.

Edit: I'm only referring to the Catalyst drivers here.

Are you talking about S3TC/DXTn/BC[1-5]? I believe the patent was filed in 1997 which should bring its expiration date to 2017 (20 years after filing).

What is STC2?
Wow the Radeon open source drivers are actually catching up to the catalyst proprietary drivers. The difference is not so great anymore. Everything above the HD 6870 is still not being fully taken advantage of in Linux, they should be yeilding a much higher FPS all round if you compare them to Windows results.
NVIDIA open source drivers...what a joke! No fault to the programmers, NVIDIA doesn't want to be open it seems... At least with the proprietary drivers, NVIDIA offers the best performance and best bang for the buck. Wish it was open source.... but I can't argue with the highest FPS yield, open or not!
intel opensource works really well for me with s3tc install, video decoding too.
i give up from older laptop woth hybrid amd/intel because the fglrx, i want see amd give up closed source and do like intel.
nvidia closed drivers works really well, only needs official optimus support. bumblebee is a great project but is not the same of windows optimus support
I'm now using Radeon over Catalyst in my E-450 powered netbook, with Fedora 19 (the very latest code, as seen on Phoronix). It's generally faster than Catalyst*, KWin 4.11 works better than ever (with NO TEARING!), the new OpenGL 3.1 compositing engine works like a charm, performance is more than acceptable and the only two things that are lacking (UVD decoding and power management) will be addressed in Linux 3.10 and Linux 3.11. Screen brightness and hardware keys are fully supported and working, something I can't say about Windows 8.
*: Watching movies and playing games is faster with Catalyst. Everything else is faster with Radeon, including max/minimizing windows, desktop effects, surfing the Web, playing Candy Crush, LibreOffice, and whatnot.

The low-end discrepancy continues: for 6450 cat/open average is 1.8, for 5830 and 6870 it's 1.4.
Looking forward to the promised SB tests, to see if that changes the low-end situation.
This post is extremely well put. I couldn't possibly agree with you more. I'm in complete agreement with you.

If you want the fastest GPU with fully Open Source drivers get an HD6870 or HD5870. The 6900 series GPUs are faster but the older VLIW5 GPUs have better support then the newer VLIW4 GPUs. The HD6870 is basically an HD5870 with better tessellation but lacking double precision OpenCL support.
