very informative. thank you for the review.
i am a photographer and I spend most of the time on lightroom too. I just replaced my late 2013 machine with the new retina one (just received it yesterday). Based on your benchmarking I can see that lihtroom on retina is a little bit responsive than the late 2013 model. do you have any explanation why I cannot sense this? i don't have numbers like yours but based on my experience here I feel the lightroom is not responsive as when it was on the older machine. when I jump between pictures it takes couple or more secs to render correctly (was instant on 2013 model). rotation on crop tool is kind of stuttering.
Am I imagining things? have i read to much negativity on this forum? or is the GPU really not as responsive with this monster screen?
Also i noticed the cooling fan kicks in more with it (while exporting) compared to the previous one.
Any thoughts?
the 2013 model I used to have:
3.5 i7
4GB GPU
16 MB ram
3TB fusion drive
the retina:
4.0 i7
4GB GPU
16 MB Ram
3TB fusion drive
You aren't imagining things re: negativity on this forum. There are many here who should have the term "hardcore whiners" tagged to their names. And it's basic human nature to loudly complain when something goes wrong, drowning out the VAST, VAST majority of users with little or no issues.
To answer your question about LR: Lightroom manages memory, and does a great job. There is only X amount that it can work with, so if you are displaying full resolution images, that memory will fill, especially when viewing at full screen.
Lightroom tries to "plan ahead", and begin fully rendering the images in the folder you are viewing -before- you get to them. But if you do it quickly, you will see that delay before the image "sharpens up".
I have a late 2012 iMac, full bells/whistles along with SSD. It renders a tad slower than the iMac Retina. Which is amazing, considering on the Retina I'm viewing has four times the pixels when compared to earlier iMacs.
Buyer's remorse is a natural occurrence. If it hits you, and you should happen to still have access to your older iMac, try this: After a day or two with the Retina, go back to the old machine. Look at some of those same images on the older machine. It's pretty shocking how flat they look, oft times boring looking. It will cure any doubts you had about this amazing machine.

I thought I read somewhere you cannot calibrate this display and it comes "pre-calibrated" from Apple.
Not true.
Apple claims they do a laser calibration of every iMac that comes off the line. But you can still use your own.
That said... I just got the Retina, and (at least mine) is by far the most accurate iMac I've had, color profile wise, straight out of the box. I haven't had time yet to do a Spyder 4 calibration, but I don't imaging I'll see much difference.
