Better to mix or multiply

Hi,

 

I am trying to measure the difference in frequency between two closely spaced 6 MHz signals. This is for a sensitive research measurement instrument. Is it better to mix or multiply to achieve highest freq. diff. resolution? Can you recommend an IC? Assume inputs are differential and can be made to any voltage level.

 

Thanks
