What does "impossible to run" here mean?

I've certainly run xbmc on my panda boards and on both video, audio
etc was fine. The interface was displaying at 1080p as would be
expected and not unusable. Sure lots of CPU might be in use, but it's
not like one is going to be running xbmc and compiling kernels at -j16
or something.

I mean on hardware without 3D support, XBMC runs very very slow.
AFAIK, the majority of platforms for STBs will not have 3D hardware support.

But platforms for Smart-TVs, theire hardwares are good, for example, 4-core SXG. On these platforms, XBMC can run well, I think.
