AMD's "486" was a 386-based design and came out almost 2 years after the i486DX33.
The AMD DX2-100 (actually called the DX4-100) also came out 2 years after the Pentium 60/66. Intel was shipping the Pentium 133 by that time.
Neither of those 2 examples was in any way competitive with what Intel was shipping at the same time. The Athlon was the first time AMD took an overall lead from Intel. Otherwise, AMD had always played the value card before that, or didn't even try to compete with mid to higher end x86 chips.
Exactly.
