It's a P2 400 but the white data label is empty. Is there a way to find the original s-spec number?

There is an Intel matrix mark in the upper left segment of the cpu which should be similar to the one on the (missing) plastic cover and contain all details. The problem is finding a reader for that type of mark.

Get your QR reader on your best cell phone with very good macro focus and try to scan and see what it says?

As alternative you can use Intel's cpu ID tool but that does only produce info on stepping & cpu ID if I remember correctly:
dA1 // 0651h
dB0 // 0652h
dB1 // 0653h

Well, a 48 MP phone (Redmi Note 8T) just isn't enough to scan this and I don't have macro lens. Tried it with a few magnifying glasses and a bunch of apps but it didn't help.

Well it predated common QR use, so might be an internal intel encoding scheme that nobody else used. You could try rubbing ink or pencil in it to improve contrast if that's the problem.

You can rule out the SECC2 S-Specs as otherwise the core would be packaged different and have a label on it.

Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.

I'm guessing it is an internal scheme, but in case it helps I coloured it in (may need to be checked for correctness).

[tried running it through a couple of readers, both as is and with the colours inverted, but no joy]

Just curious... why is it important to determine the right S-Spec ? CPUID / stepping should do, or ?

Well, I tried it too but couldn't read either. I appreciate everyone's effort though.
I collect CPUs and I'm going for a complete set that includes all the different production models. Getting a new piece of the puzzle is always exciting and this CPU could be missing from my collection. I'll send Intel customer support this image and ask them if they can help. Who knows?

This is 19x19 DataMatrix ECC0 - DataMatrix ECC140.
Online scanners and Android apps don't support this legacy format.
The AI ​​is lazy, doesn't decode, and doesn't want to study ISO/IEC 16022:2006, and only gives links to something random related to the word "DataMatrix".
So, it's not yet known what information this code contains and whether it can be useful for identifying the processor.
