Hello Marc,
obvious differences between card are memory bandwidth, intel 13 GB/sec
vs. nvidia 29 GB/s, the texture rate, 2 GTexel/s vs. 31 GTexel/s, and
pixel rate, 0.5 GPix/s vs. 15.5 GPix/s. Some of these values result
because of graphics memory differences. There is no difference in energy
consumption. Question is indeed, what do you need for doing
crystallography. If you look at the performance in popular games, the
difference is much less than you would expect looking only at the naked
values. The intel is merely 20% slower than the nvidia in most reference
games.... So, not worth spending the extra money I would say as the
actual graphics performance between cards is similar.
However, if you plan to process a lot of graphical data (video editing,
etc), the nvidia will by far out-perform the intel. Otherwise, the Intel
Iris Pro model is more than fine and you better invest your money by
getting more memory.
Best wishes
Jeroen

Hello,
I would like to buy a MacBook Pro laptop that will allow me among others
to solve structures, build models and visualize electron density maps
using Pymol, Coot or Chimera.
I have the choice between between Intel Iris Pro (5200 series) and
Intel Iris Pro + Nvidia GT 750M for the graphics cards but I don’t know
which one is fine for the programs I want to run.
Can some of you share advices/feedback with me?
Thanks a lot for your answer.
Best wishes,
Marc
