Can Macbook Pro 15 inch Late 2013 drive 4K display at 60Hz?

I do not have the Samsung 4k monitor, but I own a Dell P2715Q which is also a 4k 60hz monitor and I can confirm that it works with my 15" MacBook Pro Late 2013 (dedicated graphics) out of the box connected via miniDP -> DP. Furthermore I set the resolution to "looks like 2560x1440". Fans of the MacBook are now constantly running @ 3000-4000rpm, really annoying. Time for a new MacBook Pro with a better graphics card.

 

Opening the application folder looks a little bit sluggish, but even with my old 1080p monitor it never looked really smooth. Furthermore having several apps open and then using spaces or so is just pain in the a*s. Sluggish as f*ck. Still, I do not want to miss my 4k monitor. I just hope for a more powerful MacBook Pro so that I can drive two 4k monitors.

 

Yes it can! I'm using a 4K display with the same MacBook (with Intel Iris Pro Graphics) myself. You just have to use the Thunderbolt port to connect a mini DisplayPort Cable.
