Am486DX4-100SV8B was an Enhanced Am486 microprocessor introduced by AMD in 1996. This processor had a clock multiplier of 3 having a frequency of 100 MHz with a bus frequency of 33 MHz. This "Enhanced" Am486 includes some other features such as SMM, stop-clock control, and write-back cache. AMD later introduced the Am486DX4-100SV16B which was identical but had its L1$ doubled to 16 KB.
