Gears numbers are higher with shadowfb because it's running entirely with software rendering, and the software renderer can draw much more quickly into the system-memory FB used by shadowfb than it can draw into video memory (with EXA the master copy of the screen is in video memory rather than system memory).
I haven't found any good benchmarks for the kind of UI activities where HW acceleration really helps (scrolling etc..), so it's kinda hard to show an improvement in a benchmark today. Generally, though, small things are faster with shadowfb and big things are faster with EXA.Last edited by bridgman; 14 March 2009, 04:29 PM.

I was thinking of upgrading from my 9250 to a 780 IGP (probably) in the near future, but after a horrible experience with intel-2.6.1 I'm a bit more cautious about leaving that comfort zone where everything works perfectly...

drm-next is needed to compile xf86-video-ati 6.12.0 and can be obtained from git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6 (http version http://git.kernel.org/?p=linux/kerne...log;h=drm-next).
drm-next is also in Zen-Sources kernel already (http://zen-sources.org/content/gitby-hand-based-setup).

This is great news. How much of a difference does the EXA make in real apps though? Is 2D compositing usable with 6.12?

Slower than ShadowFB
Hi,
I made small benchmark.
Intel(R) Core(TM)2 Duo CPU T5750 @ 2.00GHz
ATI Mobility Radeon? HD 3470
Now is slower than Shadowfb
