Only if you really have a point to make about rendering differences product of something like a bug or overall testing for regressions for example . Of course, the comparison is legit as long as you take care that the renderings are THE SAME (same shaders, textures, and such) ... maybe apitrace could help with that?
Otherwise than that, this entire article is simply a waste of time for readers (if no point is made)
