On AMD's you mean? It's not the case. A load micro-op on AMD's also results in an address generation and the load operation itself. So, Intel's (unfused) micro-ops and AMD's micro-ops are indeed quite similar... It's not really the appels and oranges case, then.

Moreover, an AMD-ish macro-op consists of up to two micro-op, f.ex. an integer operation (executed by an ALU), and a load/store/load-store(same address) that results in an address generation by an AGU, and a load-store unit loading/storing the data.
