Can base 15" 2015 rMBP output 4k 60hz?

A little confused on this one. DisplayPort 1.2 supports 4k 60hz, however Apple states 4k 60hz is only supported on the 2015 dGPU model. Is the iGPU in the base 2015 holding it back from achieving 4k 60hz?

This model supports a simultaneous maximum resolution up to 3840x2160 on two external displays via Thunderbolt 2. Alternately, it can support a single display up to 3840x2160 via Thunderbolt 2 and a single 1080p display at up to 60 Hz, 3840x2160 at 30 Hz, or 4096x2160 at 24 Hz via HDMI.

Nope! My base 2015 15 retina is running off my Dell P2715Q 4k monitor @60hz with no problems. Im using a cheap mini displayport to displayport cable from amazon. I also can run my 15 inch off my vizio 4k tv @ 60hz with a display port to HDMI 2.0 cable from amazon. You shouldn't have any issues.

Awesome! I'm currently using a 43" Sony x800D as my monitor for W10. Can't wait to try it!
