Can be everywhere, but it is most likely in north bridge design.

K7VMM is an older motherboard than A7V8X, and it has
similar chipset as A7V8X. From Arne's test, it seems to have
better memory bandwidth than A7V8X.
In past, VIA designed some good chipset. It is behind others now,
but it may have other features we do not know / use.
