Best open source graphic hardware
 
Hi,

I am currently using a NVidia Geforce GTX 550 Ti under Archlinux.
I plan to use Parabola GNU Linux instead of Archlinux.
In order to achieve this, I need the best open source graphical hardware option.

NVidia support with Nouveau is not perfect especially in 3D. I experienced some lag and display bug.
I read AMD/ATI support is not perfect too.
I know this problem is due to the closed source and the politic of both NVidia and AMD.
I read good feedback regarding Intel. So why not buying a processor which support HD4000 like a Core i3 3225.

Which one is the best ? Intel ? NVidia ? ATI ?
What is the involvement of each company in open source drivers ?
Which one have the best performances ?

Thanks in advance
Regards

  • Nvidia - none.
  • ATI/AMD - they make OSS drivers for their cards. These drivers aren't yet feature complete (eg. no video decoding, not very good power saving), and have limited support for their most recent hardware (HD7xxx). Performance-wise it's nothing to be extremely proud of (50% of catalyst for high end cards). But all in all, those drivers work. They don't spare any resources for upstream development (the team is about 5 people, so that is understandable)
  • Intel - They write their own drivers, recently implemented OpenGL 3 into mesa (when their hardware started supporting it). Their drivers mostly have feature parity with their windows counterpart. Performance-wise, it's slightly worse than on windows, but nothing too dramatic.

ATM I mostly have ATI/AMD cards, and the OSS driver works well. Gaming isn't a priority though.
On the only intel card I have, I experience some weird issues (mostly related ro RandR), but it's a pretty old GMA4500, so you should be fine with their HD4000 series.

Personally I like ATI, but pragmatically Intel is a better choice if you want to go full OSS.

ATI/AMD have the most potential for performance, Intel make the most of their hardware. For benchmarks see OpenBenchmarking

Some small corrections: AMD does not make OSS drivers for their cards. They release documentation for their chips and support the driver development with paying a few developers. Not all work of these developers will be released, they have to work that out with AMD's legal department. That for one is the reason why the OSS drivers never will be feature complete (means they will never support the UVD video decoding units and power-saving will never be up to par with the proprietary drivers). But at least they are making some effort to release documentation, Nvidia refuses to do that at all, they are only supporting Linux with proprietary drivers. regarding performance, it is heavily based on the application, some applications run with a whopping 30% of the Catalyst driver's performance, some run at 80%.

If gaming is to be supported on your machine I wouldn't consider the Intel video devices an option, unless you restrict yourself to older games or low video settings. That hardware is nowhere even near the performance region of your Geforce card.

Thanks to your feedback.
Really appreciated.
I consider I have my answer.
