Phoronix: Open-Source Radeon 2D Performance Is Better With Ubuntu 14.10

While we're most often looking at the OpenGL 3D performance of the Linux graphics drivers, in the tests currently being done of Ubuntu 14.04 LTS vs. Ubuntu 14.10 are also a number of 2D graphics benchmarks. In the article today are our 2D benchmarks between Ubuntu 14.04.1 and Ubuntu 14.10 for various AMD Radeon graphics cards and it shows off significant performance improvements.

Those numbers mean CPU is now the bottleneck?

So what about CPU usage stats added to the next such test, Michael?

I was thinking the same thing.

As a Radeon HD 7870 owner it's good to see Glamor is about as fast as EXA.

I as well. Glamour should, potentially, lead to lower CPU usage, but these fairly early implementations may yet have told of draw calls and context switches.
I'm not sure if they've even handled all of the fallbacks yet.

CPU + GPU usage, please.

Michael, why are you always forgetting my Radeon R290 when running these tests?..
Since that's the newest card you have, shouldn't it always be in the tests?

Because it doesn't work out-of-the-box with Ubuntu 14.04 open drivers, so in a comparison against Ubuntu 14.04 vs. 14.10, it doesn't work.

Ah, makes sense. But didn't it work without 3D acceleration?

Mode-setting, yes. But GLAMOR (2D) acceleration depends on 3D acceleration.
