Here is the problem with his test. It is an Apples to Orange test due to the card. ATI 5870 is optimized for Motion.
That card is not optimized for After Effects. Here is the list: https://helpx.adobe.com/x-productkb/policy-pricing/system-requirements-effects.html
I used both After Effects and Motion. And the card makes a big difference. After Effects was slow for me when I did most of my work in Motion. After FCPX I switch to a Premiere and AE workflow. A matter of fact, Premiere’s real time playback was sluggish at best. When I switched over to a NVIDIA Quadro 4000 card I saw dramatic improvement in playback in AE and Premiere. Now when I jump back into Motion for a legacy project to make changes I can tell that it is sluggish. Some crazy big projects won’t even render and I have to take it into a different edit bay that has a card Motion likes.
It is not about the program but what the artist can do with the program.
