NVIDIA Is Better For Closed-Source Linux GPU Drivers, AMD Wins For Open-Source 185

Posted by Soulskill from the best-of-different-worlds dept.
An anonymous reader writes "Phoronix last week tested 65 graphics cards on open source drivers under Linux and the best result was generally with the open source AMD Radeon drivers. This week they put out a 35-graphics-card comparison using the proprietary AMD/NVIDIA drivers (with the other 30 cards being too old for the latest main drivers) under Ubuntu 14.04. The winner for proprietary GPU driver support on Linux was NVIDIA, which shouldn't come as much of a surprise given that Valve and other Linux game developers are frequently recommending NVIDIA graphics for their game titles while AMD Catalyst support doesn't usually come to games until later. The Radeon OpenGL performance with Catalyst had some problems, but at least its performance per Watt was respectable. Open-source fans are encouraged to use AMD hardware on Linux while those just wanting the best performance and overall experience should see NVIDIA with their binary driver."

      Not that odd. AMD and NVidia are both trying to find ways to tweak the standards for tiny increases in framerate, Intel is honoring the standards and improving performance by boosting the power of the hardware underneath. That means Intel will continue to lag when it comes to all the different GPU metrics (but they did close the gap a lot recently), but since they're not trying to do shortcuts with the OpenGL and DirectX standards, they are much more straightforward to use.

          The moment you go into games, game development, image processing, rendering and modeling, perhaps HD video playback (and processing?), or working with very high resolutions, your video card sure does matter, so does the quality of the drivers and its acceptance of standards (specially OpenGL).

        With Intel graphics, it just works, because the open source driver code is integrated into Linux.

      CURRENT open source drivers should work well on that card, get a more update distro or manually update the kernel, libdrm, mesa and possibly the xorg-ati driver. Also, this open drivers status is for Linux, for BSD the open status may not be as good due the missing/incomplete lower level support in the kernel

      If it is failing on a recent distro, with recent kernel and mesa , you should open a bug (sometime fixing a bug on new cards can create another on older cards due the different features available)

    In last week's testing of 65 GPUs on the open-source Linux drivers, the winner overall was the AMD Radeon graphics cards: they were the least problematic (though several Radeon GPUs still ran into different problems) and they delivered the best performance (including generally the performance-per-Watt).

    Can confirm. The open source Radeon driver has been improving greatly. A bit surprisingly, Radeon hardware is actually starting to become a quite good choice for a Linux user.

  • Yeah, as long as you ignore "NVidia Optimus". I have a AMD-A6 based desktop, it works fine with the occasional glitches, but the only thing that is truly stable and works for everything is called "Intel". There simply is no contest.

    • Depends on what you're willing to compromise. I have Nvidia Optimus, everything works perfectly for me. I had to use bumblebee and not Nvidia's own hacks, since NV's don't work yet, and bumblebee does, but it's pretty close to the Windows experience. While it doesn't auto-detect apps and select Intel/Nvidia automatically for me, it does allow me to manually force Nvidia usage much more simply, so I score that a wash.

      If we are going to be honest about things, we should also look at why: neither vendor is enthusiastic about providing complete documentation on the products.

      We should also be clear about some of the consequences. Better open source drivers provide a better long term solution under Linux. Yes, this is because Linux developers are somewhat hostile to closed source drivers. On the other hand, it is something that you should consider if you are using Linux.

    The Truth on OpenGL Driver Quality [blogspot.hu]

    TL:DR;
    Vendor A nVidia - driver errs on the side of "make it work" vs GL spec
    Vendor B AMD - conforms to the OpenGL spec, but is buggy, inconsistent performance
    Vendor C Intel - best open source driver, but performance doesn't compete with nVidia or AMD

    Vendor A

    What most devs use because this vendor has the most capable GL devs in the industry and the best testing process. It's the "standard" driver, it's pretty fast, and when given the choice this vendor's driver devs choose sanity (to make things work) vs. absolute GL spec purity. Devs playing at home use this driver because it has the sexiest, most fun to play with extensions and GL support. Most of what you hear about the amazing things GL will be able to do in order to compete against D3D12/Mantle are by devs playing with this driver. Unfortunately, we can't just target this driver or we miss out on large amounts of market share.

    Even so, until Source1 was ported to Linux and Valve devs totally held the hands of this driver's devs they couldn't even update a buffer (via a Map or BufferSubData) the D3D9/11-style way without it constantly stalling the pipeline. We're talking "driver perf 101" stuff here, so it's not without its historical faults. Also, when you hit a bug in this driver it tends to just fall flat on its face and either crash the GPU or (on Windows) TDR your system. Still, it's a very reliable/solid driver.

    Vendor A supports a zillion extensions (some of them quite state of the art) that more or less work, but as soon as you start to use some of the most important ones you're off the driver's safe path and in a no man's land of crashing systems or TDR'ing at the slightest hickup.

    This vendor's tools historically completely suck, or only work for some period of time and then stop working, or only work if you beg the tools team for direct assistance. They have enormous, perhaps Dilbert-esque tools teams that do who knows what. Of course, these tools only work (when they do work) on their driver.

    This vendor is extremely savvy and strategic about embedding its devs directly into key game teams to make things happen. This is a double edged sword, because these devs will refuse to debug issues on other vendor's drivers, and they view GL only through the lens of how it's implemented by their driver. These embedded devs will purposely do things that they know are performant on their driver, with no idea how these things impact other drivers.

    Historically, this vendor will do things like internally replace entire shaders for key titles to make them perform better (sometimes much better). Most drivers probably do stuff like this occasionally, but this vendor will stop at nothing for performance. What does this mean to the PC game industry or graphics devs? It means you, as "Joe Graphics Developer", have little chance of achieving the same technical feats in your title (even if you use the exact same algorithms!) because you don't have an embedded vendor driver engineer working specifically on your title making sure the driver does exactly the right thing (using low-level optimized shaders) when your specific game or engine is running. It also means that, historically, some of the PC graphics legends you know about aren't quite as smart or capable as history paints them to be, because they had a lot of help.

    Vendor A is also jokingly known as the "Graphics Mafia". Be very careful if a dev from Vendor A gets embedded into your team. These guys are serious business.

    Vendor B

    A complete hodgepodge, inconsistent performance, very buggy, inconsistent regression testing, dysfunctional driver threading that is completely outside of the dev's official control. Unfortunately this vendor's GPU is pretty much standard and is quite capable hardware wise, so you can't ignore these guys even though as an organization they are i
