Actually our initial implementations are 1 Gb/s per pin (500 MHz DDR)
and 8 bits wide in each direction.  I usually call that 1 GB/s, but if you
count the way the RapidIO and Infiniband folks do, it would be 2 GB/s.

The link is scalable in both frequency and width giving an aggregate
bandwidth of 12+ GB/s at 800 MHz by 32 bits wide.
