Thanks for the response Lawrence. The Broadcom BCM16K KBP has a clock speed of 1.2Ghz, so I expect the J2 to have something similar (as someone already mentioned, most chips I've seen are in the 1-1.5Ghz range), so in this case "only" 2 pipelines would be needed to maintain the headline 2Bpps rate of the J2, or even just 1 if they have managed to squeeze out two packets per cycle through parallelisation within the pipeline. Cheers, James.
