I'd say that this response does absolutely nothing to clarify things. Sure, a Pentium is a Pentium, and an AMD5x86 is not. Thanks for pointing that out to us. Now, as far as I know, there are no user level instructions in the Pentium that are not found in the 486. So, an AMD5x86 can do *essentially* everything a Pentium can. It should more or less be just a question of how the AMD performs on specific applications.
Can anyone shed some light on the relative performance of an AMD5x86?
