Differences between 13'' and 15'' rMBP for 4K output?

[evrard]

While I know the 15'' rMBP can output 60 Hz 4K via Thunderbolt 1.2, but can the 13'' rMBP? I am trying to decide if I should purchase the 13'' or 15'' - prefer the compactness and lightness of the 13''. Thanks for the help guys.

Wrong forum, but the 13 can only run 4k @ 30hz officially. You can get it up to 52 hz with a program like Switchresx. The Broadwell chipset for the 13 should be able to run @ 60hz. No one knows when that will get released.

You're right - wrong forum, my bad. Thanks for the response none the less. Wish I had the money to just get a Mac Pro! Would make running data analysis for my thesis so much faster.
