The IBM 386DX looks different because it has an aluminum top instead of plastic or ceramic. The chip inside is still the same as in the Intel 386 processors.

I pulled this chip from an IBM-PC that stopped working. Because I have no motherboard with a 40MHz oscillator crystal (needed for 20MHz operation) I can't benchmark it. However, the CPU runs fine with turbo-off in an 33MHz motherboard but then it'll run at only 8MHz.
