As per the Eurogamer leak so likely they were right about 1ghz for both portable and docked modes. Something like 18,000 mips I think.

4.6x1000x4 = 18,400mips
About 2x that of the wii u at 9,000 but a bit less than 360 and ps3.
However later architecture with a gpu less reliant on cpu assistance should give the Switch a small cpu advantage at least over 360. Also about 3x Vita cpu performance.
Roughly just under half of ps4/xbox one cpu performance.
