Am486DX2-66V8T 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 essentially identical to Am486DX2-66 apart from the process used. The new model name was used to differentiate it from the Am486DX2-66V8B which is a similar model with a Write-Back cache policy. The Am486DX2-66V16T and Am486DX2-66V16B are also similar models with double the cache size.
