Went to the Apple store today and tested the Mac Mini's handling of HD content from the Apple site. It was a dual core mini with 512 meg of ram. Downloaded the wildlife reel from Apple's web site (720p resolution) and ran it in quicktime while I played with iPhoto effects and also previewed a slide show in iPhoto that contained lots of transitions. I also played with expose repeatedly while the quicktime move played. The mini hardly ever dropped blow 29 fps. Very impressive I checked system profiler and checked the graphics card. It showed the Intel GMA950 graphics card with 256 meg of vram? Checked two minis and saw the same thing. What's with that? BTW nothing was open when I did this. I also opened activity monitor and could not see the ram utilized by the graphics card. Not sure about the info in the system profiler but I am impressed with the ability to decode HD content. Much better than my powerbook.
