Don't get me wrong its not unusable or horrific by any means but its there from what 'I' can see. However when I render a 1:1 preview zoom in and out under the develop module I can see some stutter. I have a 500gb lightroom library on an external hd with previews on my internal SSD. How many files you have, if they are on an external drive, if you are not using an ssd and etc. There are factors that contribute to the lag. Portability is not an issue for me as it will be used to run 2 monitors as a desktop, replacing a 2009 iMac for portability needs, I have an Air. I have the unit with the discrete graphics because of my growing interest in video.

The larger MBP had Iris Pro graphics, although I'm not sure of the extent of the difference. On another note.I haven't read all of the specs on the latest MBP revision, but with the late '13 models (of which my 15" is one), there was a difference in the level of Iris graphics between the 13" and 15" machines. Probably something local on OP's machine. I've haven't been reading of such a problem anywhere. There are a lot of different Retina MBPs now, so not sure why OP would just write that they have a lag in LR. Essentially one of two things has to happen, lightroom needs to be more efficient or we need faster GPUs. The dedicated GPU does reduce this UI lag a 'bit' in Lightroom but it still present. SIDE NOTE: Lightroom will run in the low res mode when you use an external monitor. This causes lightroom not to run in the Retina resolution but it looks pixelated but its darn fast. The other way to rid of completely is to run Lightroom is 'LOW-RES' mode. Its not unusable by any means it just annoying to see it.
You can reduce it greatly by rendering 1:1 previews but it still lags. Oh, and just as a side note, Lightroom's UI is somewhat laggy with the Retina Macbooks still unfortunately. Though if I get a 13" later I will most likely get a 27 or 30" monitor when I need the extra screen real estate. The only benefit with the 15" 'for me' is the bigger screen. Also I use an app called GFXcardstatus to use only my integrated GPU and not the GT650m in my machine so I can get extra battery life and less heat. It nothing to do with the savings but more with the portability. When I replace my 2012 retina macbook pro at some point in time I will seriously consider the 13" model. If you're doing video editing then a dedicated gpu is going to render faster for sure but if you're doing photo editing I don't think it helps that much in my opinion. Honestly I don't care about a dedicated GPU anymore now that Intel Iris is good enough for my uses. The are certainly times I really wish I had the 13". I shoot with a Canon 5D and a Sony NEX 5. I have a 2012 15" Retina Macbook Pro and use it for my personal photography.

But other than the advantage of the larger screen size (and disadvantage of larger size and weight), are there any other advantages to the 15 inch pro? For example, I see that the 13 inch pro only comes with Intel Iris graphics, and the higher end 15 in models have graphics cards - will that make any difference, when using things like Lightroom and Photoshop? Also, the 15 inch macbook pros all come with core i7 chips, and most of the 13 inch pros come with i5 (or the cost of upgrade to i7 makes it almost as much as the 15 in version) - again, for what I want to use it for, would the i7 make any difference over the i5? The advantage of the 13 in macbook pro is that the money I save (over the 15 in version) can almost pay for the external monitor. Dell U2413), leaving it in clamshell mode and using external keyboard and mouse/trackpad. I understand I can attach the macbook pro to an external monitor (eg. Also, I plan to eventually get a good 24 or 27 in external monitor, for photo editing primarily.
I am debating between the new 13 vs 15 in macbook pros, either way I would max them out with 16 GB RAM and a 1 TB SSD. I want to replace my 4 year old 15 in Macbook pro (non-retina).
