I'm not exactly sure myself, though both terms seem to cover both the electrical and software interface involved in inter-processor communications. The A an APIC stands for "Advanced" and is a method patented by Intel. The O in OPIC stands for "Open" and is an open standard that does the same thing without infringing on the patent. However, because of the patent(s?) it can't be totally compatible. This info may be a little fuzzy, as it dates back to the release of the K6, and I can't remember what the "PIC" stands for.
