Intel Sandy Bridge Linux Graphics? It's A Challenge

Agree, it didn't seem like a valid test. Still wondering where the proper benchmark is. The phoronix test suite documentation link doesn't give a clue.

well can we even really advocate using the phoronix test suite until Michael changes the board software to finally allow a longer edit time

we could then come back and edit our posts and add that info and recommendations

(just pulling your leg Michael , but consider that a continually repeated request from several users)


i guess you could give http://unigine.com/products/heaven/ benchmark a try, it says it has Support of DirectX 9, DirectX 10, DirectX 11 and OpenGL 4.0 hardware
and lists a Linux version (233 Mb): download so i assume you will get some form of consistent result at least

Out of the open source stuff used for benchmarking within the suite, Warsow is one that I personally think is fun to play. It should be in Redhat's package manager. ~400MB download. Once you start, use ` to bring up a console and type /set cg_showfps 1 (if I'm remembering correctly). You would probably need to go into the advanced graphical settings and raise your max FPS value. To make it easier for us to get an idea of what kind of performance you're getting I would suggest using the predefined quality settings (low, medium, high).

Running any one of the gaming benchmarks would be a good start with pts.

GLXgears is not a benchmark. The only thing that the numbers are useful for is to tell you if you have hardware acceleration or not.

Hmm, you probably have glxgears on your system. It doesn't really tell a whole lot outside of very basic 3d throughput.

*** NOTE: Don't use glxgears as a benchmark.
OpenGL implementations are not optimized for frame rates >> 60fps,
thus these numbers are meaningless when compared between vendors.

Well glxgears is horribly slow on my core i7-2600k. Looks reminiscent of glxgears on a system that is melting down with full I/O load, yet the system is idle:

% glxgears
Xlib:  extension "NV-GLX" missing on display "unix:0.0".
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
361 frames in 5.3 seconds = 68.130 FPS
300 frames in 5.0 seconds = 59.994 FPS
300 frames in 5.0 seconds = 59.994 FPS
300 frames in 5.0 seconds = 59.994 FPS
300 frames in 5.0 seconds = 59.994 FPS

As measured with what? I don't use any 3d apps under linux so I don't know offhand. I could fire up a benchmark if I was pointed in the right direction.

How's the 3D performance?

There's a fedora rpm for the 2.14 X server now, so a:
yum --enablerepo=rawhide update xorg-x11-drv-intel
should eliminate the need to compile it from source.
