Phoronix: Intel SNA vs. UXA On Ivy Bridge (July 2012)

Here are some recent benchmarks comparing Intel's SNA and UXA 2D acceleration architectures offered by their open-source Intel Linux graphics driver.

I'm still with UXA because glx-dock (cairo-dock) gets corrupted very quickly with SNA.

Intel are doing awesome work, very impressive.

Some people on different forums reported weird flickering and artefacts with Intel HD 2000/3000 GPUs rendering this new feature useless. Can someone confirm it?

I'm using SNA on my OpenSuse 12.1 under an Ivy Bridge CPU, I don't have any graphical artefact. I noticed that it seems smoother in general.


I'd like to precise that the line to add in xorg.conf is exactly (in the driver section):

Option "AccelMethod" "SNA"

Confirmed. I have an i5-2467M (Sandy Bridge). Using SNA I started getting corruptions as soon as X is started. It usually happens with overlay dialogs with drop shadows. Switching back to UXA, corruptions are all gone.

Great work. Intel rocks.

Thank you Intel.

Do you have a link to this bugreport?

Do you have a link to this bugreport?

No, I was hoping it would go away with 2.20.1 but no luck.

Intel is doing an AMAZING job. Congrats!
