I'm trying to source a used Xeon processor (Broadwell generation) for an old machine, and boy either A) There were multiple packaging plants resulting in lots of different printing styles or B) There's fucktons of weird reprinted cpus out there. But since the unlocked multiplier 'counterfeit' cpus are pretty much not a thing anymore, what would be the point of shipping a relabeled CPU? It's obviously not going to show up in the BIOS/CPU-Z correctly, so you might as well ship them a rock if you're going to scam them, no? I guess that's an argument for, there's probably just weird variations on printing, in particular between retail and OEM server CPUs, which there are tons of in the used market. It has printing of this style (not this exact image/model):

Any way to tell after you fire it up? From cpuid output or similar. Presumably I'd need to find sources for exact stepping information for shipped CPUs, including OEM versions if it's one of those. That seems... unlikely. I could only find https://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/xeon-e3-1200v4-spec-update.pdf which refers only to steppings "G - 0" (the number zero) as a collective. No idea how to interpret that if I get a CPU that has some particular stepping value. Presumably steppings A-F would be pre-production then? But I have no clue.
