With millions of transistors there will be errors. The error hunt can start early on in the chip design libraries. Eliminate these early errors and they do not reach the final stage masks. AMD might have better tools than Intel. Intel might be house-tool bound and AMD selects the best tools on the open market? Then test exhaustively in emulation, with an emulator that has fewer errors and finally make a part, test that to death, fix all you find and test some more. Ideally there is a large degree of parralellism so it can proceed rapidly.

I'm afraid you totally missed my point. With chips as complex as the PIII and Athlon, there will be errata.

It doesn't matter what testing tools and methodologies you use. The chips themselves (not to mention their environment) are too complex to ensure absolute perfection.
