Public bug reported: Not much to say here. I can clearly see that during Superkey+W (unity shortcut) or Ctrl+Shift+E in Firefox animations on Intel are smoother. Some time ago I quit using AMD on my system because browser performance was unbearable - see http://askubuntu.com/questions/92080/why-do-i-have- poor-video-performance-in-browsers-with-a-ati-hd3650-gpu for details (video + overall experience).
In 12.04 the difference was much more severe. In 12.10 the difference is less pronounced (Firefox performance on AMD got better), but it's still noticeable (12.10, desktop perf.: Intel vs AMD). I acquired *.apport files from different configurations on my system, so let me know what's needed to move the troubleshooting further.
