The AMD-X5-133ADZ was a high-performance 486-based microprocessor introduced by AMD in 1996 as part of their Am5x86 family. This processor had a clock multiplier of 4x, operating at 133 MHz with a bus speed of 33 MHz. This MPU had all the features offered by AMD's Enhanced Am486 such as a large 16 KB L1$ and various power management features. AMD marketed this chip as Pentium-75-comparable performance. 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.
