With all my past experience and recent research, I know that the graphics, pixel variations and clock speeds in GHz can be confusing to most. But from what I understand, Intel is 5000 and Iris is 5100, which suggests being of better graphics, however...I have not compared the visual on screen difference, that is where it can get tricky with your screen resolutions and basic hardware that is installed on the system. Iris 5100 could be better, but with a certain combination of hardware it may not be as effective than it normally would in a different configuration. I hope that makes sense, this can loose a person in a minute.
