There's a pair of Intel LGA 3647 CPUs on ebay, but seller does not know what they are and is selling them as defective and for parts (for a good price)...

The text on the CPU is

INTEL CONFIDENTIAL
QL5C
J6140520 04
Any idea what they are? Bronze? Platinum? 4C? 22C?

I was curious, just looked them up. Second one (last pic) has at least two capacitors broken off. Look at right edge of caps down at the bottom, and compare with first processor... first shows 8 horizontally, second shows 6 and what look like broken pads.
Also, top center is missing a “big” capacitor.

Are they important ones? No clue. Could you try to repair or bridge? Maybe- but the pads appear gone on the big cap— meaning a full solder bridge may be the only way to try... no thanks! Let us know if you decide to try, you are braver than I am!

I was about to close... chip 1 is missing a big cap at bottom left.
maybe you could reflow/combine them?

QLxx are bad, they are an early, somewhat buggy stepping that only boots on HP servers and Supermicro boards with a pre-3.0 BIOS.
