Template:mpu i486SX2-66 was a fourth-generation x86 microprocessor introduced by Intel in the early 1990s. This chip, which is based on the 80486 microarchitecture, had a clock doubler operating at 66 MHz, twice the bus speed. In contrast to the i486DX chips, the i486SX line had no functional FPU on-die.
