It looks like a re-post of the original pic. If you could flip the processor over and send in a pic that would tell us more about it.
If you look at the circuit board on the right hand side .... look at where the screw went through at the very bottom. It looks like that board might have a gold trace. ( They're more often copper. ) It's like a very thin foil made into the layers of the green board. It's about like gold leaf. There's not a lot of gold there, but, it is more likely a higher grade of board.
The eight pointed thing underneath ? No idea what it is or what it does. The metal pointy things might have a thin gold plating on the outside. You can tell if it's plated by taking a grinder or file to it. You'll be able to see the base metal underneath.
