My experience differs. I have not seen dramatically different performance in practice between coot running on nvidia and the same program version running on Intel HD4000. Yes the OpenGL benchmarks are radically different, but that doesn't seem to reflect what is acheived by programs of interest. I notice more of a difference in Pymol performance, but not such a huge difference as to be a problem. > but with the appearance of HD 5000 series (Iris > HD) the Cinebench OpenGL score increased dramatically and even > challenges many nvidia cards in performance.
