History
After 386 competitors appeared, Intel in 1992 lowered the price of the 25-MHz 80486SX to less than that of the 33-MHz 80386. An industry analyst said that Intel wanted customers to move to the competition-free 486. The strategy was very successful; by 1993 Dell reported that 80486-based computers were 70% of sales. AMD continued to create clones, releasing the first-generation Am486 chip in April 1993 with clock frequencies of 25, 33 and 40 MHz. Second-generation Am486DX2 chips with 50, 66 and 80 MHz clock frequencies were released the following year. The Am486 series was completed with a 120 MHz DX4 chip in 1995.
