AMD marketed this chip as Pentium-75-comparable performance. Due to this processor's high operating temperature rating, it became a favorite among computer enthusiasts who often overclocked it to 160 MHz (with a bus of 40 MHz). Some AMD-X5-133ADZ were remarked and sold as fake AMD-X5-160; other systems advertised "160 MHz" 5x86 which simply used an overclocked 133ADZ as well.
