Looks like someone may have dropped the ball over at Newegg, judging by one of the banner slides on the main page:
Do you see what we see? The Galaxy Nexus, now with 800MHz moar processor! It's clearly a typo, but it's pretty lulz all the same. Fortunately, the actual cell phone landing page has the correct specs, so hopefully no one out there will be picking up the good old GN thinking they're going to be clocking the fastest speeds known to man in a mobile device.
