Am486DX2-66V8B was an 80486-compatible microprocessor introduced by AMD in 1994. This processor had a clock multiplier of 2 having base frequency of 66 MHz with a bus frequency of 33 MHz. This model is a variation of Am486DX2-66V8T (previously Am486DX2-66) with 8 KB Write-Back cache instead of Write-Through. The Am486DX2-66V16T and Am486DX2-66V16B are also similar models with double the cache size.
