Am486DX2-66V16B - AMD
Template:mpu Am486DX2-66V16B was an Enhanced Am486 microprocessor introduced by AMD in 1997. This processor had a clock multiplier of 2 having base frequency of 100 MHz with a bus frequency of 50 MHz. This model had a write-back cache and double the size of L1 of previous models (16 KB). The Am486DX2-66V8T is an 8 KB version similar to this model. This "Enhanced" Am486 includes some other features such as SMM.
