I think it's a 80386 CPU. I found old thread discussing this chip (scroll to Karolo's question):

It is a 386 for sure. I have the same chip (51F1784) from an IBM PS/2: http://www.cpu-collection.de/?l0=i&i=2263

I have a couple of IBM chips like that - but no information.
Does there exist any kind of list that says 73G14587H1364 (IBM;-) = 386/20MHz or so?

I still have the machine that holds it. I'll be back in town next week. I will check the PS/2's modell number and try to find out. Maybe I can manage to boot it - the bios battery is dead and the system just shows an error number...

Yes, the IBM 51F1784 is a 386 with 20 MHz. The machine I got it from is an IBM PS/2 8570-081 386DX/20.
