> Even a 2014 macbook pro with amd graphics is sluggish on 4k.

I have a late 2013 MBPR (NVIDIA GT750M) with an external 4K monitor in portrait mode connected via DisplayPort, plus the laptop's display. Both are running at 60Hz. I don't see any sluggishness or mouse lag at all; everything is very smooth.

I mostly run Windows 10 on this machine, but it also works fine when I boot in to OSX.

I thought the macbook with amd was fine on 4k especially after getting the right cable for 60hz. The i5 with intel 530 is better. Maybe it is because graphics cards are designed more for 3d processing than for general 4k performance. I tried playing a 2d shooting game on each and for whatever reason the intel 530 system was less latent and much easier to win. The macbook is as smooth as the intel 530 when on its native screen but not when it drives a 4k screen.

I'm sure he's talking about MBPs with only Intel graphics (which frankly seemed a little underpowered for the Retina display much less a 4k monitor).

Actually not: "a 2014 macbook pro with amd graphics".

A while back I tested a 2014 MBPR with the AMD GPU vs. my late 2013 model with NVIDIA, and the AMD was a bit faster.

Not sure how I missed that...
