    Tossing up between the 455 and 460. Just wondering if anyone could comment on the performance of 455 driving an external 5K monitor(extended mode).

    I used to own the first 13" retina 2012, the HD4000 was so choppy just driving its OWN screen, I got migraine headaches.

    On that note, how's the battery life for the 460? I'm leaning on the 455 for the better battery life on the road, only if it's good at driving a 5K when docked.

    I will use it mainly for PS and light video editing amongst other light office work. Thx!

    Edited for clarity

    If you are driving an external display you don't beef to worry about battery life?

    Well, considering the LG UltraFine 5K display, you won't need to worry about your battery life because it will charge itself just by being plugged in. Other unsupported display, I'm less sure.

    You must have practical expectations. Quartz is tough to render at retina resolutions so even higher is going to have some jerkiness depending on the app.

    The cost of upgrade is so low compared to the benefit you get. 460 is a no brainer.

    I already got a 15" MBP but didn't upgrade to 460, so I have a 455.

    I plan on getting the 5K Ultrafine display. I don't do any heavy graphics stuff - I only want the big display because of its screen real estate to run different (mainly office-related) apps next to each other. And I want it to be retina resolution.

    Is jerkiness expected in such a setup? I don't have much experience with graphic cards (as I never did any graphic intensive things), but when reading this, it's making me wonder if I should get the 4K Ultrafine instead.


    I think his question is whether the 460 uses more battery while on the road (ie. not connected to the 5K display) than the 455.

    I don't know that, although you can just use the integrated GPU instead of the dGPU while you're mobile, so the battery will surely last a lot longer. Try gfxCardStatus for that.

    Yeah, it's the tradeoff subtlety I'm trying to distinguish with everyones help here. If the 455 drives macOS UI fine on 5K, then i'm all for it.

    I actually upgraded to a 15" late 2013 with the geforce 750m (using right now). It's a bummer that every time I fire up PS, it uses the dGPU regardless of the actual workload. No way to force it to use the iGPU. Same thing with other slightly more intensive programs. It's hard to get this machine through a good days work whilst I'm out.

    gfxCardStatus stopped working for later revisions of macOS. =(

    Bootcamp kills battery life it as well. About 2hrs on the machine I'm using. =/

    Ok, personally recommend to upgrade to 460 purely due to GPU is always being a bottleneck for laptops

    even the 450 will drives the 5K display just fine, since its just a UI size, if try to gaming or some other real time 3D rendering at 5K resolution, good luck lol, but PS and video editing performance should having nothing or very little to do with UI size, so if stay at 455, it should, or very likely to serve its purpose.

    battery life, your talking about battery life on 2016 MBP? XDXD think you already know what I mean. while theres no intensive load, under idle there should be no noticeable power consumption different between 455 and 460, in theory. I personally using a 460, 2.7 and locked to iGPU by using system command, and the battery goes to around 15% after around 5.5 hours of Youtube video + 30~ tabs opened at background.

    So even though the monitor is very likely to charge your computer, but if still talking about battery life regardless, since the external monitor will result in dGPU kick in, the battery life, is going to be, just simply bad. And for the previous module, like the ones with GT750M, the iGPU is physically not connecting to the external display, so if you force the computer to lock on iGPU to prolong battery life, without disabling the graphic restriction when you connecting to the monitor, you will get nothing but a total blank, and for the 2016 module, did not try yet, but very likely to be the same, so don't even want to expect battery life while using a external monitor

    What are you doing that eats up the battery so fast? Brightness up high or something? Even with 30 tabs open, you should be getting better battery life than that when just streaming video.

    brightness up to around 3/4 or full brightness, I already starting to assume that this is how this gen's battery is really like, alone with all the other complains at some other Mac forums, of course I am planning to have a full wipe and reinstall, I hope it can get better after that, but I'm only hoping, not really looking forward to that.

    and I am also planning to run a full-to-empty drain test by simply play some 10 hour video on youtube, after I get hands on another 15', but not now.
