First I can't follow the 80% math, on the OpenCL benchmark that they got the 80% number. At best the iMac 2015 has 74% performance of the 2017 iMac at the top end of both. Additionally, when you are still in the same ball park as with the high end of the Mac Pro, from 2013, seems also wrong. A lot has happened in the GPU space in the last 4 years, so this seems odd. Maybe it isn't fair to compare to the Mac Pro, as it isn't clear if that GPU was SLI'd or not, but it's their graph. Of course there is no comparison to other non-apple systems. I'm flagging this story as it's pure fluff, in my eyes.

Perhaps, but there's no denying the GPU updates in this refresh are substantial relative to the old ones, in no small part due to how outdated the GPUs in the previous generation were. Heck just being able to purchase a 21.5 inch model with a discrete GPU is a giant leap forward!
