256bit interface 7600GT AGP??

Newegg is currently listing two xfx 7600gt classes one of which is listed as having a 256 memory interface.

Now this is probably an error but afte googling the part number, I found a couple other sites (they don't seem as reputable as newegg to me but oh well) that have this product listed; mostly out of stock. They also list it as having a 256bit memory interface.

The part number PVT73AUDE3 yields no results from the XFX site so far. The stats are all the same as the xxx edition 7600GT AGP except for the 256bit interface.

This is probably just some big confusion or someone in marketing entering something wrong or something. However do you guys think this could be a real product? I wonder if anyone out there knows anything about this at all.
