Internal differences between 6400 & 6600?

Looking at it from a 10,000 ft overview, what are the differences in circuit internals between the 6600 & 6400? Is it mostly software differences or does one have a different bill of materials? (Ie, more & better goodies). Thanks!

    6600 has two spectral capture units and can do 4 receiver slices

    They're based on a modular design. The contest grade preselectors plus the additional SCU in the 6600 are the main differences. They may have additional modules (MARS etc) to add on in the future.
