The AM486DX5-133W16BGC 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.
