I've had an offer of a batch of older CPUs (486/Pentium era) and in the group are these two that I just can't identify.
They both have non-descript heatsinks on top (just black, plain fins, no fans), and the markings on the bottom don't reveal anything through furious Googling

Anyone have any idea on these two?

The top one must be a 486 DX2, notice the 1992 copyright. That's the release year for that CPU.

I don't know about the other one

That's a good hint! It looks like the SX626 486 DX2-50 has a CPUID of 432, which is on the bottom markings of this one. The bottom of the SX807 looks very similar to this as well!
Maybe the closest I'll get without throwing it in a board and seeing what I can get it to run as.

Thanks!

I got these CPUs and for reference, the top was indeed a 486 DX2-50 and the bottom was a 486 DX2-66. Case closed!
