AMD Radeon Gallium3D Starting To Out-Run Catalyst In Some Cases
Phoronix: AMD Radeon Gallium3D Starting To Out-Run Catalyst In Some Cases
In this article are benchmarks of the past two Ubuntu Long-Term Support releases (Ubuntu 12.04.1 LTS and Ubuntu 10.04.4 LTS) compared to the latest Ubuntu 13.04 development state. Being looked at specifically for this round of testing is the AMD Radeon Linux graphics performance with the latest open-source driver compared to an older Catalyst driver. For an AMD Radeon HD 4800 series graphics card, the current state of the open-source graphics driver on Linux is beginning to outperform an old AMD Catalyst driver from 2010 for select Linux OpenGL games.
Quite impressive. Great job by those involved!
Michael you have overdone yourself :P
48xx can only support OpenGL 3.3. So when r600g supports geometry it will have OpenGL support on pair with Catalyst drivers (and do not know if Catalyst support OpenGL ES 3.0!).
Fix that in your article.
Btw. ETA on geometry shaders anyone?
Well done radeon team!
ETA for smooth on-demand power management? Currently I still have to manually switch profiles, and dynpm (?) flickers a lot.
Thanks for all your great work!
I was talking in more broad terms at the end than just specific to the lone graphics card used for this article.

No, it shouldn't be, because when s3tc extension is missing a texture just aren't filled by data, so texture will be just blank and nothing more. If these games have support for both compressed and non compressed textures (when s3tc ext is missing) some small performance drop may be visible, but for mid-end cards like a tested HD4830 it shouldn't be a visible difference in performance (of course it depend on textures count, but I think that these games doesn't need too much bandwith for a textures).

Now my R700 card is used for videos only, but even here it's very impressive - full HD content is shown on screen without any stuttering, even when the card is set on the low profile (which it is pretty much permanently for me now, as there is no more reason to go any higher).
Well, you might want to clarify that in the article, then. I wanted to make the same comment...

Also, I'd be curious how much, if at all, the catalyst performance has gone up for that card over the last few years. I'd imagine some, but not much, and possibly has gone down as they would be focusing on newer cards.
Lastly, we'd need to know if the image quality settings were identical for each benchmark.
Regardless, fantastic job to all the radeon crew!
As I understand from you statements ,you are using your video card for video acceleration. Now my question is: how are you doing that? With Catalyst or with Gallium driver? I have a HD 4570 and now with Ubuntu 12.04.2 which uses a 3.5 kernel, Catalyst no longer support my card. For now I'm pleased with the graphics performance, but when it comes to video acceleration... everything sucks. And it seems that my Dual Core Pentium T4300 can't handle Full HD decoding.
