Just wanted to clarify that you have to select advanced map generation in order to see the 16k map option. From the basic screen only 4k and 8k are available.
Or you could use a modlet and have 4096, 6144, 8192, 10240, 12288, 14366, 16384 as options on both menus (New Game and Advanced/Previewer).

Anyway, been doing testing on my own system:
Gigabyte X58A-UD3R v2 BIOS version: FH
Intel Xeon W3680 3.325 GHz (25x133) @ 4.20 GHz (25x168) [6 Cores/12 Logical], QPI x44, Uncore x21
24GB G.Skill DDR3 Triple Channel {F3-14900CL8-4GBXM * 6} @ 1680 MHz (CL 8, tRCD 8, tRP 8, tRAS 20, Command Rate 1T)
Gigabyte GeForce GTX 1070 8GB DDR5 GV-N1070G1
Windows 7 Ultimate 64bit -- InstallDate 2012 (Last Re-install)
Below were all done with the same seed and all same configs/installed mods. Only one-off testing so far to get baselines. Memory is just me eyeballing TaskManager.
Map Size, Amount of memory used to Generate and Full Preview (zoom all the way out to see radiated edges), and the time the logs list for Generation

16k
22GB Map * No Full Preveiw - Attempts to zoom out hit the upper limit of memory on my machine (24GB) and cause out of memory issues.
